Crypto for everyone - libsodium in PHP 7.2 - Marcus Bointon
 
56:25
PHP 7.2 includes the libsodium cryptography library by default in the base language - the first time that a popular language has shipped with strong, modern crypto support as standard. Everyone can build secure apps without the risks of rolling your own crypto or using outdated libraries. So what's in libsodium? What kind of things can you do? What risks remain? You'll get a tour of cryptographic functions, how they have been done in the past (and what was wrong with them), and how to switch to libsodium to give you a security edge.

Bitcoin Q&A: Passphrases and seed storage
 
14:14
Do passphrases protect against leaks or compromises of mnemonic seed words? Why are brain wallets usually insecure? Why should you not "roll your own crypto" and promote creative schemes that deviate from the standards (like BIP39), without at least getting peer review and testing from other developers, cryptographers, or security researchers?

Security vs. Complexity
 
29:54
In this talk, Andreas reflects on the audacity of "be your own bank," but also the difficulties we will face in translating what that means to people who still have no idea what a bank (let alone the centralised power of the banking cartel) does. We all suffer from the Dunning-Kruger effect, but in security it can be fatal. We need to be better at accurately calculating, conceptualising, prioritising and defending against risks faced by a diverse, global user base. We need to design interfaces that are intuitively secure. Or we will lose the safeguards of decentralisation to "crypto banks" -- same business as usual, but new names on the letterhead.

Cryptography: Crash Course Computer Science #33
 
12:33
Today we’re going to talk about how to keep information secret, and this isn’t a new goal. From as early as Julius Caesar’s Caesar cipher to Mary, Queen of Scots, encrypted messages to kill Queen Elizabeth in 1587, theres has long been a need to encrypt and decrypt private correspondence. This proved especially critical during World War II as Allan Turing and his team at Bletchley Park attempted to decrypt messages from Nazi Enigma machines, and this need has only grown as more and more information sensitive tasks are completed on our computers. So today, we’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard (AES), Diffie-Hellman Key Exchange, and RSA which are employed to keep your information safe, private, and secure. Note: In October of 2017, researchers released a viable hack against WPA2, known as KRACK Attack, which uses AES to ensure secure communication between computers and network routers. The problem isn't with AES, which is provably secure, but with the communication protocol between router and computer. In order to set up secure communication, the computer and router have to agree through what's called a "handshake". If this handshake is interrupted in just the right way, an attacker can cause the handshake to fault to an insecure state and reveal critical information which makes the connection insecure. As is often the case with these situations, the problem is with an implementation, not the secure algorithm itself. Our friends over at Computerphile have a great video on the topic: https://www.youtube.com/watch?v=mYtvjijATa4 Produced in collaboration with PBS Digital Studios: http://youtube.com/pbsdigitalstudios Want to know more about Carrie Anne? https://about.me/carrieannephilbin The Latest from PBS Digital Studios: https://www.youtube.com/playlist?list=PL1mtdjDVOoOqJzeaJAV15Tq0tZ1vKj7ZV Want to find Crash Course elsewhere on the internet?

#1 KnowKnowledge | WiFi Hacking ? | Authentication Explained | TechFeast India
 
14:47
****************** FOR EDUCATION PURPOSES *********************** Hey! Guys, what's up? This is the first video of #KnowKnowledge And I Priyansh is going to explain some of the Authentication Story! And are you keeping your wifi secure by using WPS in your router! Given Below are some of the history of WiFi Authentication! :- Wired Equivalent Privacy (WEP) Wired Equivalent Privacy (WEP) is the most widely used Wi-Fi security algorithm in the world. This is a function of age, backwards compatibility, and the fact that it appears first in the encryption type selection menus in many router control panels. WEP was ratified as a Wi-Fi security standard in September of 1999. The first versions of WEP weren’t particularly strong, even for the time they were released, because U.S. restrictions on the export of various cryptographic technology led to manufacturers restricting their devices to only 64-bit encryption. When the restrictions were lifted, it was increased to 128-bit. Despite the introduction of 256-bit WEP encryption, 128-bit remains one of the most common implementations. Despite revisions to the algorithm and an increased key size, over time numerous security flaws were discovered in the WEP standard and, as computing power increased, it became easier and easier to exploit them. As early as 2001 proof-of-concept exploits were floating around and by 2005 the FBI gave a public demonstration (in an effort to increase awareness of WEP’s weaknesses) where they cracked WEP passwords in minutes using freely available software. Despite various improvements, work-arounds, and other attempts to shore up the WEP system, it remains highly vulnerable and systems that rely on WEP should be upgraded or, if security upgrades are not an option, replaced. The Wi-Fi Alliance officially retired WEP in 2004. Wi-Fi Protected Access (WPA) Wi-Fi Protected Access was the Wi-Fi Alliance’s direct response and replacement to the increasingly apparent vulnerabilities of the WEP standard. It was formally adopted in 2003, a year before WEP was officially retired. The most common WPA configuration is WPA-PSK (Pre-Shared Key). The keys used by WPA are 256-bit, a significant increase over the 64-bit and 128-bit keys used in the WEP system. Some of the significant changes implemented with WPA included message integrity checks (to determine if an attacker had captured or altered packets passed between the access point and client) and the Temporal Key Integrity Protocol (TKIP). TKIP employs a per-packet key system that was radically more secure than fixed key used in the WEP system. TKIP was later superseded by Advanced Encryption Standard (AES). Despite what a significant improvement WPA was over WEP, the ghost of WEP haunted WPA. TKIP, a core component of WPA, was designed to be easily rolled out via firmware upgrades onto existing WEP-enabled devices. As such it had to recycle certain elements used in the WEP system which, ultimately, were also exploited. WPA, like its predecessor WEP, has been shown via both proof-of-concept and applied public demonstrations to be vulnerable to intrusion. Interestingly the process by which WPA is usually breached is not a direct attack on the WPA algorithm (although such attacks have been successfully demonstrated) but by attacks on a supplementary system that was rolled out with WPA, Wi-Fi Protected Setup (WPS), designed to make it easy to link devices to modern access points. Wi-Fi Protected Access II (WPA2) WPA has, as of 2006, been officially superseded by WPA2. One of the most significant changes between WPA and WPA2 was the mandatory use of AES algorithms and the introduction of CCMP (Counter Cipher Mode with Block Chaining Message Authentication Code Protocol) as a replacement for TKIP (still preserved in WPA2 as a fallback system and for interoperability with WPA). Currently, the primary security vulnerability to the actual WPA2 system is an obscure one (and requires the attacker to already have access to the secured Wi-Fi network in order to gain access to certain keys and then perpetuate an attack against other devices on the network). As such, the security implications of the known WPA2 vulnerabilities are limited almost entirely to enterprise level networks and deserve little to no practical consideration in regard to home network security. Unfortunately, the same vulnerability that is the biggest hole in the WPA armor, the attack vector through the Wi-Fi Protected Setup (WPS), remains in modern WPA2-capable access points. Although breaking into a WPA/WPA2 secured network using this vulnerability requires anywhere from 2-14 hours of sustained effort with a modern computer, it is still a legitimate security concern and WPS should be disabled (and, if possible, the firmware of the access point should be flashed to a distribution that doesn’t even support WPS so the attack vector is entirely removed).

#deskofladyada LIVE SAMD51 @microchipmakes @adafruit #adafruit
 
48:41
https://blog.adafruit.com/2017/08/01/the-atsamd51-is-here-adafruit-microchipmakes-atsamd51/ Wow some awesome release news from Microchip about a fancy new chip that just dropped. If you know us (and you’re reading this blog so yeah you probably do) you know we just luuuuv the ATSAMD21 – featured in our M0 Feathers, Metro M0 and even the new Gemma M0 we just put in the shop. The ATSAMD21 has always felt to us like the next evolution for fans of the 8-bit AVRs like the ATmega and ATtiny series – with 256 KB of flash, 32 KB of RAM, 48 MHz Cortex M0+ chipset, USB, tons of timers, peripherals, ADC, DAC, up to 6 SPI/I2C/UART devices… using the SAMD21 feels so roomy and comfortable. Adafruit 2132 One of the most fun projects we’ve had over the last year is porting MicroPython to the ATSAMD21 (which we call CircuitPython since the API deviated a bit). Now, MicroPython works just fine on the SAMD21 and you can build many projects quickly, using the built in Python 3 interpretter. And while we absolutely adore it, it’s just a *little bit* sluggish on the ATSAMD21 as its only a Cortex M0 at 48MHz, and doesn’t have any hardware floating point support. And 32KB of RAM is huge for Arduino but CircuitPython can run out of memory if you’re doing a lot. As we started exploring CircuitPython more and more it became clear we could really use an upgrade path. So we asked Microchip “heyyyy so is there like an upgrade to the atsamd21 that’s maybe a cortex m3 or m4, with more RAM and maybe 100 MHz?” and they were all like “maaaybeeee….plz sign this NDA” and we were like “sweet!” and we got a bunch of ATSAMD51 chips and a datasheet! You can check out the no-longer-sekret datasheet here (PDF). The ATSAMD51 is to the ATSAMD21 as it was in turn to the ATMega328. More! Better! Faster! Here are some quick specs: Cortex M4 core running at 120 MHz Hardware DSP and floating point support Up to 1 MByte flash, 192 KB RAM Sizes ranging from 48-QFN to 128-TQFP (the 48 QFN is *nearly* pin compatible with the ATSAMD21 but it isnt 100% drop in compatible) Some neat new peripherals/upgrades: Built in 1.8V buck for lower power uses (needs an external inductor) Dual 1MSPS DAC Dual 1MSPS ADC Parallel capture controller (for camera/video in) Built in crypto engines with AES (256 bit), true RNG, Pubkey controller Ethernet MAC on the SAME5 series QSPI for fast SPI transfers CAN Bus SD/MMC controller “configurable custom logic” – this one is particularly interesting/weird, you get latches and LUT you can link up PDEC – rotary encoder hardware support The speed, and extra space makes it excellent for our next generation of CircuitPython boards, and the price is pretty good too – only about $3 each for the ATSAMD51G19 in reel qty. Considering its the same list price as an ATmega32u4 it’s an easy choice for us! We also like that the pricing is so competitive with other Cortex M4 suppliers, e.g. STM32F405RGT6 is ~$6.50/1K pcs and the similar ATSAMD51J20A is $3.70 (the STM is faster, the SAM has more RAM, it was hard to find a perfect 1:1 comparison) compared to the Kinetis K20 series (famous for being used in the Teensy 3.2) the MK20DX256 has 25% of the Flash size, 25% as much RAM, 60% of the speed, but costs $1-1.25 more. Competition is heating up! Ambahlahdolnogpf Any how, the Atmel ATSAMD51 series looks really awesome to me, and its now public and you can order some chips even from microchip direct. Some chips are in stock now, such as the ATSAMD51N20A-AU, ATSAMD51P19A-AU, others will be shipping in late October. We’ve already started designing a Feather M4 and Metro M4 and we’ve even gotten it going with Arduino core with some tweaks to the current SAMD core. Img 7279 Excited to try out this chip? We don’t have hardware for sale quite yet (and likely won’t until chips are shipping in larger qty in November) but if you have early hardware access for some reason you can check out our forked Arduino SAMD codebase at https://github.com/adafruit/ArduinoCore-samd/tree/samd51 for our latest code – full 120MHz clocking, GPIO, ADC, DAC, I2C/SPI/UART, USB all basically work but there’s a few tweaks and bugfixes still. The BOSSA bootloader working here: https://github.com/adafruit/ArduinoCore-samd/tree/samd51/bootloaders/x1 and the software bootloader tool here: https://github.com/adafruit/BOSSA_x1/tree/arduino We hope to get these all merged into mainline soon, and also a CircuitPython port that can take advantage of the awesome power that can be unleashed! ----------------------------------------- Visit the Adafruit shop online - http://www.adafruit.com Subscribe to Adafruit on YouTube: http://adafru.it/subscribe Join our weekly Show & Tell on G+ Hangouts On Air: http://adafru.it/showtell Watch our latest project videos: http://adafru.it/latest New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ Music by bartlebeats: http://soundcloud.com/bartlebeats -----------------------------------------

Tricks to hack hashed passwords
 
06:53
As we know, hash function/algorithm is used to generate digest/checksum of data. Hash function is not reversible. However, it can be hacked, and it is easy. In this video, I will use some websites to crack hashed passwords manually. You can see how easy to hack hashed passwords if hackers use powerful computer or clusters of computers to hack our passwords. They would crack millions every second. Do not assume your passwords are safe as long as they are hashed into non-reversible digests.

hardwear.io 2017:- TEMPEST Attacks Against AES by Craig Ramsay
 
44:42
Side-channel attacks can recover secret keys from cryptographic algorithms (including the pervasive AES) using measurements such as power use. However, these previously-known attacks on AES tend to require unrestricted, physical access to the device. Using improved antenna and signal processing, Fox-IT and Riscure show how to covertly recover the encryption key from two realistic AES-256 implementations while: 1. Attacking at a distance of up to 1 m (30 cm in realistic conditions; "TEMPEST"), 2. Using minimal equipment (fits in a jacket pocket, costs less than €200) and 3. Needing only a few minutes (5 minutes for 1 m and 50 seconds for 30 cm.) To the best of our knowledge, this is the first public demonstration of such covert attacks from a distance.

Finney Phone World's First Blockchain Smartphone -Made by Sirin Labs
 
03:44
Finney Phone World's First Blockchain Smartphone -Made by Sirin Labs The upcoming device, known as the Finney (after bitcoin pioneer Hal Finney), is said to run on a secure, open-source operating system called Shield OS, built on Android. This would “incorporate advanced blockchain and cryptocurrency trading algorithms” for secure transactions, as well as “blockchain applications, such as a crypto wallet, secure exchange access, encrypted communications,” and more. A 5.2-inch QHD display, 8 GB of RAM, 256 GB of internal storage space, as well as a 16 MP main camera and 12 MP wide-angle selfie camera (the chipset it will make use of hasn’t yet been mentioned). But the device is not yet in production, and won’t be available for an estimated nine months after the crowdfunding campaign. Let me offer up a few reasons why you might want to tread carefully on this one. It’s set to be developed following a crowdfunding campaign in October, and will start at $999. *Blockchain ~ a bit about blockchain: A blockchain is a shared database that doesn’t rely on a single trusted party to maintain it but instead is based on a network of connected devices that all maintain it. It was originally built to support bitcoin, and has major implications for security. The data is “public” and thus isn’t liable to any internal fiddling, and because it’s not stored in a single space, it’s harder for hackers to tamper with or exploit the system (though not impossible). Integrating a blockchain into a smartphone system is an interesting idea and could increase overall safety and accountability. But Sirin Labs’ application of the cryptocurrency support it provides could set alarm bells ringing.

AnonCom: Extreme Encrypted Private Android Phone
 
12:03
AnonCom takes Anonymity to the crowd IndieGoGo.com - http://igg.me/at/AnonCom/ We have entered an age of endangered privacy, where surveillance of our actions and exchanges as citizens is absolute. Though aware of the constant invasion on their privacy, the average person does not know how to protect themselves nor their data from prying eyes. AnonCom decided to make it simple. Large corporations that are offering to protect your data are actually interested in protecting it only from other corporations, not from themselves nor interested third parties. And of the companies specifically offering encrypted devices, such as Boeing, are defense contractors funded by the most invasive rulers known to man. Now, there is an affordable anonymous cell phone. [video] https://www.youtube.com/watch?v=bnrPTOi9EEE With built in system level encryption, encrypted private phone calls, text messages, emails, and even built in TOR anonymous browsing, the AnonCom system helps keep your data in your hands. Combined with the ability to provide information you define, such as a fake location, phone number, and more - you can decide what information they see. AnonCom uses Curve25519, AES-256, and HMAC-SHA256. Messages sent via text are end-to-end encrypted so they can only be read by the intended recipients. It's easy to verify that you are communicating with the intended recipient, and that no MITM attack has occurred. The encryption keys are stored only on the device, and are protected by an additional layer of encryption with a passphrase. No one has access to the contents of any messages sent by users. The Axolotl ratchet, the most advanced cryptographic ratchet available, creates new AES keys for every single message. With all the features you would expect from the latest cell phones, they also included the unexpected. The two least expensive models offer 4G LTE connectivity on a handset that has a built in Fingerprint ID system that can also be assigned at application level. Of course the handset is also protected by password for decryption before the convenience of the fingerprint scanner can be used. Weatherproof and shockproof options are also available on the AnonCom X6, which also included a built in UHF two way radio and external antenna. This beast is nicknamed "The Survivalist" - and with good reason. It's built to handle the toughest environments. The project leader said "The average person needs to be protected, and they just don't have the knowledge or patience to do it themselves". Further explaining that despite his belief that knowledge is free, he thought it was important to build a self sustainable system to bring anonymous communications to the masses. "My sister was not going to dowload and install TOR, even though she knows she should. I had to do if for her." "Ordinary citizens, working together, can change the world" Edward Snowden Join the crowd starting this week on IndieGoGo.com - http://igg.me/at/AnonCom/

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ A smart lock is an electromechanical lock which is designed to perform locking and unlocking operations on a door when it receives such instructions from an authorized device using a wireless protocol and a cryptographic key to execute the authorization process. It also monitors access and sends alerts for the different events it monitors and some other critical events related to the status of the device. Smart locks can be considered part of a smart home. Smart locks, like the traditional locks, need two main parts to work. The lock and the key. In the case of these electronic locks, the key is not a physical key but a smartphone or a special key fob configured explicitly for this purpose which wirelessly will perform the authentication needed to automatically unlock the door. Smart locks allow users to grant access to a third party by the means of a virtual key. This key can be sent to the recipient smartphone over standard messaging protocols such as e-mail or SMS. Once this key is received the recipient will be able to unlock the smart lock during the time specified previously by the sender. Smart locks are able to grant or deny access remotely via a mobile app. Certain smart locks include a built-in WiFi connection that allows for monitoring features such as access notifications or cameras to show the person requesting access. Some smart locks work with a smart doorbell to allow the user to see who and when someone is at a door. Smart locks may use Bluetooth SMART and SSL to communicate, encrypting communications using 128/256-bit AES.

HOW TO CRACK MD5 HASH USING CAIN AND ABEL
 
01:45
What is an MD5 hash? An MD5 hash is created by taking a string of an any length and encoding it into a 128-bit fingerprint. Encoding the same string using the MD5 algorithm will always result in the same 128-bit hash output. MD5 hashes are commonly used with smaller strings when storing passwords, credit card numbers or other sensitive data in databases such as the popular MySQL. This tool provides a quick and easy way to encode an MD5 hash from a simple string of up to 256 characters in length. MD5 hashes are also used to ensure the data integrity of files. Because the MD5 hash algorithm always produces the same output for the same given input, users can compare a hash of the source file with a newly created hash of the destination file to check that it is intact and unmodified. An MD5 hash is NOT encryption. It is simply a fingerprint of the given input. However, it is a one-way transaction and as such it is almost impossible to reverse engineer an MD5 hash to retrieve the original string.

The iStorage datAshur is the world’s most secure, easy to use and affordable USB flash drive, employing PIN code access with military grade AES 256-bit hardware encryption. The datAshur incorporates a rechargeable battery allowing the user to enter a 7-15 digit PIN onto the on-board keypad before connecting the drive to the USB port. All data transferred to the datAshur is encrypted in real-time with the built in hardware encryption engine and is protected from unauthorised access or if your datAshur is lost or stolen. The datAshur automatically locks when unplugged from the host computer or power to the USB port is turned off. The datAshur operates straight out of the box, does not require any software or drivers to be installed and is compatible with PCs, MACs, Linux and embedded systems. The datAshur delivers drag and drop encryption, plug and play simplicity and can be used with any off the shelf backup software. The datAshur can be configured with independent User and Admin PINs, making it perfect for corporate and government deployment. If the User forgets their PIN, the drive can be unlocked using the Admin PIN which will then clear the old User PIN and allow the User to set a new PIN. The datAshur also incorporates a drive reset feature which clears both User and Admin PINs, destroys the data, creates a new randomly generated encryption key and allows the drive to be reused. The datAshur is capable of generating an infinite number of randomly generated encryption keys, allowing the user to reset the drive as and when required. As the iStorage datAshur is unlocked via the on-board keypad and not via a keyboard, it is not vulnerable to software/hardware based key-loggers or brute force attacks. The datAshur protects your data with a “Brute Force Hack Defence Mechanism”, which deletes the encryption key and destroys all stored data if the incorrect PIN is entered a total of 10 consecutive times. The datAshur is an investment that will last for years. Its rugged, extruded aluminium, water proof casing is tamper evident and protects it against physical damage. The internal drive components are also sealed with a tamper proof coating. This video was created and is owned by iStorage Ltd and full credit goes to them for it.

Bluestacks is a Silicon Valley-based mobile company that produces BlueStacks App Player and GamePop. Both products are designed to enable Android applications to run on Windows PCs, Macintosh computers and TVs. Investors include [1] Andreessen-Horowitz, Redpoint, Samsung, Intel, Qualcomm, Citrix, Radar Partners, Ignition Partners and others. The company was founded in 2009 by Rosen Sharma, former CTO at McAfee and a board member of Cloud.com. BlueStacks is Sharma’s 8th company, with five acquisitions by Google, Microsoft, Citrix X 2 and McAfee. BlueStacks exited beta on June 7, 2014. Products The company was officially launched May 25, 2011, at the Citrix Synergy conference in San Francisco. Citrix CEO Mark Templeton demonstrated an early version of BlueStacks onstage and announced that the companies had formed a partnership. The public alpha version of App Player was launched on October 11, 2011.[2] App Player is a downloadable piece of Windows and Mac software that virtualizes the full Android experience. The software is free, but then charges $2/month unless you download apps from Bluestacks sponsors.[3] On June 27, 2012, the company released an alpha-1 version of its App Player software for Mac OS.[4] while the beta version was released on Dec 27, 2012. According to company sources it can run over 750,000 Android apps on Mac[5] It reached the 10 million download mark in May, 2013 The company’s latest product GamePop was launched on May 9, 2013. It uses a subscription-model. Users will receive over $250 worth of paid games with their subscription. [6] GamePop will allow users to play as many as 500 mobile games on TV. On July 23, 2014 Samsung announced [7] it had made an investment in and was backing GamePop. This brought total outside investment in BlueStacks to 26 million. On The technology page of Bluestacks' Website, an image titled "BlueStacks supports multiple OS configurations" shows it running Android on Chrome OS, with a caption below saying "Android on Chrome OS (for x86): Run Android apps in a browser tab to augment the app experience in Chrome OS". However as of January, 2014, the software is not available on the Chrome Web Store. Reception App Player has received mixed reviews. Its latest version (0.8.3.3026) received 3.5 out of 5 stars on CNET Download.com.[8] The top user complaints are the lag issue, especially when running graphic intensive apps and the fact that it did not provide a mechanism to uninstall cleanly. history of whatsapp In June 2009, Apple launched push notifications, letting developers ping users when they were not using an app. Koam updated WhatsApp[clarification needed] so that each time the user changed their statuses, it would ping everyone in the user's network.

How To Lock or protect any Drive, Pendrive, Storage etc without any software or without any download
 
05:13
By follow the steps of this video you will be able to lock any pendrive, Drive, Storages and files. You need no internet or data connections. No softwares, No downloads. Just follow the steps and lock your drive and protect your files for free. BitLocker is a full disk encryption feature included with Microsoft Windows versions starting with Windows Vista. It is designed to protect data by providing encryption for entire volumes. By default, it uses the AES encryption algorithm in cipher block chaining (CBC) or XTS mode[6] with a 128-bit or 256-bit key.[7][8] CBC is not used over the whole disk; it is applied to each individual sector. History BitLocker originated as a part of Microsoft's Next-Generation Secure Computing Base architecture in 2004 as a feature tentatively codenamed "Cornerstone",[10][11] and was designed to protect information on devices, particularly in the event that a device was lost or stolen; another feature, titled "Code Integrity Rooting", was designed to validate the integrity of Microsoft Windows boot and system files.[10] When used in conjunction with a compatible Trusted Platform Module (TPM), BitLocker can validate the integrity of boot and system files before decrypting a protected volume; an unsuccessful validation will prohibit access to a protected system.[12][13] BitLocker was briefly called Secure Startup prior to Windows Vista being released to manufacturing. Availability BitLocker is available on: Ultimate and Enterprise editions of Windows Vista and Windows 7 Pro and Enterprise editions of Windows 8 and 8.1[1][2] Pro, Enterprise, and Education editions of Windows 10[3] Windows Server 2008[4] and later[5][1] Initially, the graphical BitLocker interface in Windows Vista could only encrypt the operating system volume. Starting with Windows Vista with Service Pack 1 and Windows Server 2008, volumes other than the operating system volume could be encrypted using the graphical tool. Still, some aspects of the BitLocker (such as turning autolocking on or off) had to be managed through a command-line tool called manage-bde.wsf.[14] The version of BitLocker, included in Windows 7 and Windows Server 2008 R2, adds the ability to encrypt removable drives. On Windows XP or Windows Vista, read-only access to these drives can be achieved through a program called BitLocker To Go Reader, if FAT16, FAT32 or exFAT filesystems are used.[15] In addition, a new command-line tool called manage-bde replaced the old manage-bde.wsf.[16] Starting with Windows Server 2012 and Windows 8, Microsoft has complemented BitLocker with the Microsoft Encrypted Hard Drive specification, which allows the cryptographic operations of BitLocker encryption to be offloaded to the storage device's hardware.[17][18] In addition, BitLocker can now be managed through Windows PowerShell.[19] Finally, Windows 8 introduced Windows To Go in its Enterprise edition, which BitLocker can protect. Operation BitLocker is a logical volume encryption system. (A volume spans part of a hard disk drive, the whole drive or more than one drive.) When enabled, TPM and BitLocker can ensure the integrity of the trusted boot path (e.g. BIOS and boot sector), in order to prevent most offline physical attacks and boot sector malware.[32] In order for BitLocker to encrypt the volume holding the operating system, at least two NTFS-formatted volumes are required: one for the operating system (usually C:) and another with a minimum size of 100 MB, which remains unencrypted and boots the operating system.[32] (In case of Windows Vista and Windows Server 2008, however, the volume's minimum size is 1.5 GB and must have a drive letter.)[33] Unlike previous versions of Windows, Vista's "diskpart" command-line tool includes the ability to shrink the size of an NTFS volume so that this volume may be created from already allocated space. A tool called the BitLocker Drive Preparation Tool is also available from Microsoft that allows an existing volume on Windows Vista to be shrunk to make room for a new boot volume and for the necessary bootstrapping files to be transferred to it.[34] Once an alternate boot partition has been created, the TPM module needs to be initialized (assuming that this feature is being used), after which the required disk encryption key protection mechanisms such as TPM, PIN or USB key are configured.[35] The volume is then encrypted as a background task, something that may take a considerable amount of time with a large disk as every logical sector is read, encrypted and rewritten back to disk.[35] The keys are only protected after the whole volume has been encrypted, when the volume is considered secure.[36] BitLocker uses a low-level device driver to encrypt and decrypt all file operations, making interaction with the encrypted volume transparent to applications running on the platform.

DEF CON 23 - Eijah - Crypto for Hackers
 
55:52
Hacking is hard. It takes passion, dedication, and an unwavering attention to detail. Hacking requires a breadth of knowledge spread across many domains. We need to have experience with different platforms, operating systems, software packages, tools, programming languages, and technology trends. Being overly deficient in any one of these areas can add hours to our hack, or even worse, bring us total failure. And while all of these things are important for a well-rounded hacker, one of the key areas that is often overlooked is cryptography. In an era dominated by security breaches, an understanding of encryption and hashing algorithms provides a tremendous advantage. We can better hone our attack vectors, especially when looking for security holes. A few years ago I released the first Blu-Ray device key, AA856A1BA814AB99FFDEBA6AEFBE1C04, by exploiting a vulnerability in an implementation of the AACS protocol. As hacks go, it was a simple one. But it was the knowledge of crypto that made it all possible. This presentation is an overview of the most common crypto routines helpful to hackers. We'll review the strengths and weaknesses of each algorithm, which ones to embrace, and which ones to avoid. You'll get C++ code examples, high-level wrapper classes, and an open-source library that implements all the algorithms. We'll even talk about creative ways to merge algorithms to further increase entropy and key strength. If you've ever wanted to learn how crypto can give you an advantage as a hacker, then this talk is for you. With this information you'll be able to maximize your hacks and better protect your personal data.
