PyCrypto – The Python Cryptography Toolkit PyCrypto, extended in PyCryptoDome; keyczar – Cryptography Toolkit keyczar; M2Crypto – M2Crypto is the most complete OpenSSL wrapper for Python. Cryptography – Python library which exposes cryptographic recipes and primitives. PyNaCl – Python binding for libSodium (NaCl)
The first requires 2 118 known plaintexts, 2 228.8 time and 2 228 memory. The other attack requires 2 116 known plaintexts and 2 121 memory but also requires 2 237.5 time. Serpent is a symmetric key block cipher that was a finalist in the Advanced Encryption Standard (AES) contest , in which it ranked second to Rijndael . [ 2 ]
In cryptography, truncated differential cryptanalysis is a generalization of differential cryptanalysis, an attack against block ciphers. Lars Knudsen developed the technique in 1994. Whereas ordinary differential cryptanalysis analyzes the full difference between two texts, the truncated variant considers differences that are only partially ...

w – The length of a word in bits, typically 16, 32 or 64. Encryption is done in 2-word blocks. u = w/8 – The length of a word in bytes. b – The length of the key in bytes. K[] – The key, considered as an array of bytes (using 0-based indexing). c – The length of the key in words (or 1, if b = 0).
These tables compare the ability to use hardware enhanced cryptography. By using the assistance of specific hardware, the library can achieve greater speeds and/or improved security than otherwise. Smart card, SIM, HSM protocol support
Salsa20 and the closely related ChaCha are stream ciphers developed by Daniel J. Bernstein.Salsa20, the original cipher, was designed in 2005, then later submitted to the eSTREAM European Union cryptographic validation process by Bernstein.
