RSA Algorithm is the example for Public Key Encryption algorithm. Here we are supposed to find two keys 1) Public Key which is used at encryption 2) Private Key which is used at decryption step 1: Select two large Primes P , Q Step 2: Calculate n=P*Q & O(n) = (P-1)*(Q-1) Step 3: Assume e and d (Public and Private Key). Step 4: Encrypt the Plain Text using Public Key e. Step 5: Decrypt the Cipher Text using Private Key d.

Public Key Encryption Public-key encryption is a cryptographic system that uses two keys a public key known to everyone and a private or secret key known only to the recipient of the message. Example: When John wants to send a secure message to Jane, he uses Jane's public key to encrypt the message. Jane then uses her private key to decrypt it. An important element to the public key system is that the public and private keys are related in such a way that only the public key can be used to encrypt messages and only the corresponding private key can be used to decrypt them. Moreover, it is virtually impossible to deduce the private key if you know the public key.

Special thanks to Stitch Fix for hosting this event! Mini ==== Tyler McMullen on Delta CRDTs Tyler will do his best to summarize and get you hooked on the three papers listed below: • https://arxiv.org/pdf/1410.2803.pdf • https://arxiv.org/pdf/1603.01529.pdf • http://dl.acm.org/citation.cfm?id=2911163 Tyler's Bio Tyler McMullen is CTO at Fastly, where he’s responsible for the system architecture and leads the company’s technology vision. As part of the founding team, Tyler built the first versions of Fastly’s Instant Purging system, API, and Real-time Analytics. Before Fastly, Tyler worked on text analysis and recommendations at Scribd. A self-described technology curmudgeon, he has experience in everything from web design to kernel development, and loathes all of it. Especially distributed systems. Main Talk ==== Kevin Burke on "Curve25519 and fast public key cryptography" ( https://cr.yp.to/ecdh/curve25519-20060209.pdf ) Kevin's Bio Kevin Burke (https://burke.services) likes building great experiences. He helped scale Twilio and Shyp, and currently runs a software consultancy. Kevin once accidentally left Waiting for Godot at the intermission.

=================================================== Get the code from here: https://gum.co/vefiy =================================================== This code implements RSA encryption algorithm in matlab which depend on generating very large prime numbers (there is an implemented function to generate the prime numbers randomely), these numbere are used as encryption and decryption keys using the RSA algorithm for encryption and by seperating keys as private and public as explained in the video. The code takes a text file as an input and use the content as the message to be encrypted and then the sent encrypted message along with its decryption is printed.

This clip from the 2008 Royal Institution Christmas Lectures shows a simple demonstration of how two people can agree on a secret key, even though all of their communications are carried out in public. In the electronic world, secret key exchange allows computers to communicate securely, and is used, for example, when you give your credit card information to an on-line shop. You can watch the 2008 Royal Institution Christmas Lectures in full at: http://research.microsoft.com/~cmbishop or by visiting the Royal Institution web site. There is a dedicated web site to accompany the 2008 Christmas Lectures, with ten interactive games as well as downloadable PDF instructions for experiments which can be conducted at home or at school: http://www.rigb.org/christmaslectures08

A digital signature is equivalent to a handwritten signature in paper, and a digital signature serves three basic purposes. Digital signature is commonly used for software distribution, financial transactions and other cases where it is important to detect forgery. Digital signatures are very popular with e-mail users. In this video, I will talk about the digital, uses, and the whole process of creating and sending digitally signed document over the Internet. Keep in mind, digital signature is not about encrypting document, just like paper-based signature.
