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)
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
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).
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 ...

However, in cryptography, code has a more specific meaning: the replacement of a unit of plaintext (i.e., a meaningful word or phrase) with a code word (for example, "wallaby" replaces "attack at dawn"). A cypher, in contrast, is a scheme for changing or substituting an element below such a level (a letter, a syllable, or a pair of letters, etc ...
Note that a "break" is any attack that requires less than 2 128 operations; the 6-round attack requires 2 64 known plaintexts and 2 126.8 operations. Bruce Schneier thought highly of IDEA in 1996, writing: "In my opinion, it is the best and most secure block algorithm available to the public at this time." (Applied Cryptography, 2nd ed.)
6–8 rounds per input word recommended Ascon is a family of lightweight authenticated ciphers that had been selected by US National Institute of Standards and Technology (NIST) for future standardization of the lightweight cryptography.
