Symmetric Key and Public Key Encryption
 
06:45
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

Jason Zhang – Make “Invisible” Visible: Case Studies in PDF Malware
 
43:42
https://www.hacktivity.com Due to the popularity of the portable document format (PDF), malware writers continue to use it to deliver malware via web downloads, email attachments and other infection vectors in both targeted and non-targeted attacks. It is known that PDF attackers can break detection by using polymorphic techniques to hide malicious code, randomizing JavaScript, obfuscating embedded shellcode or using cascading filters. Malware writers have always tried hard to develop new techniques to bypass detection. Some recent PDF attack campaigns we have seen are typical examples of such new endeavors from malware writers: a) Simple but effective URL aliasing technique to download malware. b) Using PDF to deliver specific topic related text content for search engine poisoning. c) Encapsulating PDF malware inside a PDF file to break detection. In this paper we will investigate the recent PDF malware campaigns using - and often abusing - these new techniques.

FREE File Encryption and Decryption Software in JAVA
 
12:20
You can download the source code and the executable from here: https://github.com/arlenebatada/File-Encryption-and-Decryption-Application-in-JAVA Do you wish to convert your music to a form in which others cannot listen it? Do you wish to convert your movies to a form in which others cannot watch them? Do you wish to convert your documents to a form in which others cannot read them? Do you wish to convert your executable files to a form in which others cannot execute them? If your answer to any of the above questions is "YES" then this software is definitely for you. With this software you can perform ENCRYPTION and encrypt your video files, audio files, text files, executable files, pdf, or any other file of your choice. This way, without your password, files such as movies, music, pdf, documents, images, etc. won't open. Executable files will no longer be in a state to be executed. Would you like to have your encrypted files back in the form they used to be? Don't worry. It is also other way around. With the password you had used for encryption you can perform DECRYPTION and convert your files back to their original form. Moreover, the application does NOT store your passwords. Instead it uses SHA-512 hashing algorithm to verify the password.

Cryptography, Perfect Secrecy and One Time Pads | Two Minute Papers #25
 
05:43
Cryptography helps us to communicate securely with someone in the presence of third parties. We use this when we do for instance, online banking or even as mundane tasks as reading our gmail. In this episode, we review some cipher techniques such as the Caesar cipher, rot13, and as we find out how easy they are to break, we transition to the only known technique to yield perfect secrecy: one time pads. Are they practical enough for everyday use? How do our findings relate to extraterrestrial communications? Both questions get answered in the video. Additional comment: "In modern certification cryptanalysis, if a cipher output can be distinguished from a PRF (pseudo random functions), it's enough to deem it broken." - Source: https://twitter.com/cryptoland/status/666721478675668993 ______________________ The paper "Cipher printing telegraph systems: For secret wire and radio telegraphic communications" is available here: http://math.boisestate.edu/~liljanab/Math509Spring10/vernam.pdf You can try encrypting your own messages on these websites: http://practicalcryptography.com/ciphers/caesar-cipher/ http://rot13.com/index.php http://www.braingle.com/brainteasers/codes/onetimepad.php Subscribe if you would like to see more of these! - http://www.youtube.com/subscription_center?add_user=keeroyz The thumbnail background was created by Adam Foster (CC BY 2.0) - https://flic.kr/p/b99vsi Splash screen/thumbnail design: Felícia Fehér - http://felicia.hu Károly Zsolnai-Fehér's links: Patreon → https://www.patreon.com/TwoMinutePapers Facebook → https://www.facebook.com/TwoMinutePapers/ Twitter → https://twitter.com/karoly_zsolnai Web → https://cg.tuwien.ac.at/~zsolnai/

Will Quantum Computers break encryption?
 
15:45
How do you secure messages over the internet? How do quantum computers break it? How do you fix it? Why don't you watch the video to find out? Why does this description have so many questions? Why are you still reading? What is the meaning of life? Facebook: https://www.facebook.com/frameofessence Twitter: https://twitter.com/frameofessence YouTube: https://www.youtube.com/user/frameofessence CLARIFICATIONS: You don't actually need a quantum computer to do quantum-safe encryption. As briefly mentioned at 7:04 , there are encryption schemes that can be run on regular computers that can't be broken by quantum computers. CORRECTIONS: [2:18] Technically, you can use any key to encrypt or decrypt whatever you want. But there's a specific way to use them that's useful, which is what's shown in the video. [5:36] In RSA, depending on exactly what you mean by "private key", neither key is actually derivable from the other. When they are created, they are generated together from a common base (not just the public key from the private key). But typically, the file that stores the "private key" actually contains a bit more information than just the private key. For example, in PKCS #1 RSA private key format ( https://tools.ietf.org/html/rfc3447#appendix-A.1.2 ), the file technically contains the entire public key too. So in short, you technically can't get the public key from the private key or vice versa, but the file that contains the private key can hold more than just the private key alone, making it possible to retrieve the public key from it.

What Is Encryption, And Why Is It Important? - Newsy
 
01:33
Encryption has become a controversial topic in the U.S., so if you're not sure what it is, listen up. Transcript: Here's a question: What is encryption? Simply put, encryption keeps your information and communication private on the web. It works like this: You fire up your computer and head over to Amazon to buy — anything, really — and at some point, you have to pull out a credit card to pay. Amazon and other stores on the web will scramble your payment information (so it essentially looks like gibberish) before it's sent to online sellers' accounts. When it arrives, the info is then unscrambled, and the money can pass through without out anyone stealing your credit card info. The encrypted part of this transaction was in between you (the buyer) and the seller. Encryption also helps secure your email, home banking and even your Facebook and WhatsApp sessions. But the practice has come under fire lately as it's been linked to terrorism. The U.S. government has tried and is still trying to force tech companies to create backdoors for the encrypted communication we all use. The problem is that encryption only works as intended if third parties don't have a key. And privacy experts say if a backdoor is created, even with the best of intentions, it's only a matter of time before people and even other governments you really don't want to have the keys get them.

All references to Section 1031 and/or like-kind exchange should be ignored. Tether CANNOT be used as a tax shield, transactions into and out of Tether are taxable, as are all crypto-to-crypto transactions!

Malware Analysis   Quick PDF Analysis
 
02:27
Ring Ø Labs report and sample download here: http://www.ringzerolabs.com/2017/08/we-show-how-to-quickly-analyze.html Ring Ø Labs Analysis Environment Setup: https://www.youtube.com/edit?o=U&video_id=Onqql1Zz3OE Ring Ø Labs is a Reverse Engineering site dedicated to analyzing malware, researching emergent security topics, and hacking the planet. www.RingZeroLabs.com Here are some approaches in reverse engineering a malware sample: Reverse engineer: The most obvious approach is to completely reverse engineer a piece of malware. This obviously takes a great amount of time, so other approaches are more practical. Exploitation techniques: Another approach you can take is to focus on the exploitation techniques of a piece of malware. Occasionally you will see a piece of malware that is using a new exploitation technique, or is exploiting a zero-day vulnerability. In this case you may be interested only in the specific exploitation technique so you can timebox your analysis and only look at the exploitation mechanisms. Obfuscation: Malware will often obfuscate itself and make itself difficult to analyze. You might come across malware that you have seen before without obfuscation. In that case you may only want to focus on reverse engineering the new parts. Encryption methods: A common type of malware these days is ransomware. Ransomware essentially encrypts the victim's files and locks them up so that they can't be accessed or read. Oftentimes the authors of ransomware will make mistakes when they implement the encryption mechanisms. So if you focus your research on the encryption mechanisms you might be able to find weaknesses in their implementation and/or you might be able to find hard-coded keys or weak algorithms. C&C communication: This is something that is pretty commonly done when looking at malware. Analysts often want to figure out what the communication protocol is between a piece of malware on the client's side and the server on the command and control side. The communication protocol can actually give you a lot of hints about the malware’s capabilities. Attribution: Murky area - kind of like a dark art. It usually involves a lot of guesswork, knowledge of malicious hacking teams and looking at more than one piece of malware. Categorization and clustering: You can reverse engineer malware from a broader point of view. This involves looking at malware in bulk and doing a broad-stroke analysis on lots of different malware, rather than doing a deep dive. Techniques Now, let’s look at techniques that can be utilized while analyzing malware. First of all, we use static analysis. This is the process of analyzing malware or binaries without actually running them. It can be as simple as looking at metadata from a file. It can range from doing disassembly or decompilation of malware code to symbolic execution, which is something like virtual execution of a binary without actually executing it in a real environment. Conversely, dynamic analysis is the process of analyzing a piece of malware when you are running it in a live environment. In this case, you are often looking at the behavior of the malware and looking at the side effects of what it is doing. You are running tools like process monitor and sysmon to see what kinds of artifacts a piece of malware produces after it is run. We also use automated analysis. Oftentimes if you are looking at malware you want to automate things just to speed up the process to save time. However, use caution, as with automated analysis sometimes things get missed because you are trying to do things generically. If a piece of malware contains things like anti-debugging routines or anti-analysis mechanisms, you may want to perform a manual analysis. You need to pick the right tools for the job.

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. Speaker Bio: Eijah is the founder of demonsaw, a secure and anonymous content sharing platform, and a Senior Programmer at a world-renowned game development studio. He has over 15 years of software development and IT Security experience. His career has covered a broad range of Internet and mid-range technologies, core security, and system architecture. Eijah has been a faculty member at multiple colleges, has spoken about security and development at conferences, and holds a master’s degree in Computer Science. Eijah is an active member of the hacking community and is an avid proponent of Internet freedom.

In this video I'm explaining what is that Galois Counter Mode that provides Authenticated Encryption with Associated Data (AEAD). You must have heard it combined with AES, and maybe used in TLS, ... This is just a small explanation, you can get more on the NIST specs. Errata (thanks to Casper Kejlberg-Rasmussen in the comments) error at 11:21, the last M_H that is applied before going into the TAG should not be there if you compare your drawing to the diagram on https://en.wikipedia.org/wiki/Galois/Counter_Mode.

MD5 Hash Tutorial - What the MD5 hash means and how to use it to verify file integrity.
 
05:45
Please like / share / subscribe if you like my MD5 hash tutorial! Here I explain how you use the MD5 hash of a file to verify its integrity in a simple MD5 hash tutorial. We use a windows based utility, md5sum.exe (http://www.etree.org/md5com.html) to check the integrity of a picture before and after we make an almost imperceptible change. Of course, we need not have used a picture, we could use any digital file to demonstrate the power of the MD5 hash for file integrity checking. As you will see in the video, using MD5 hashing, you can guarantee / verify the integrity of a Word document, a picture, a sound or video file or a software application. Reasons an integrity check might fail could be through file corruption on disk, communications corruption while downloading or even unauthorised tampering. I hope you enjoy the video, more coming soon.
