NeedForCryptography

A cryptographic library for python.

About NeedForCryptography

NeedForCryptography is meant to be a cryptographic library. It will provide solutions for main problems in cryptography and many ciphers(some of them often used and other for educational purposes only). The project is inspired by the Cryptography course at FMI.

==========

Here is a list of things that will be implemented in the library. All of them will have unit tests. These who have a suffix "(until June 2nd)" are predictions for "Milestone 1" task of the Python course at FMI:

• Common problems:

• Generation of large primes (until June 2nd)

• Decomposiotion of prime divisors (until June 2nd)

• Pohlig-Hellman algorithm for finding discrete logarithm in Zn (until June 2nd)

• Еlectronic signature (until June 2nd)

• Generate a random bit

• Secret sharing schemes

• Ciphers:

• Playfair (until June 2nd)

• Caeser (until June 2nd)

• L. Hill (until June 2nd)

• RC6 (until June 2nd)

• DES

• 3DES

• Feistel

• RSA

• MacEliece

• Diffie–Hellman

Undercover

About Undercover

Undercover will be a django web application(Crypto-Chat) which uses NeedForCryptography. Users will be able to:

• Share their public keys
• Send encrypted messages
• Decrypt messages
• Enter their private key
• Have an unique identification using "Electronic signature".
