NaCl (Networking and Cryptography Library, pronounced "salt") is a public domain, high-speed software library for cryptography. [2]NaCl was created by the mathematician and programmer Daniel J. Bernstein, who is best known for the creation of qmail and Curve25519.
crypt is a POSIX C library function. It is typically used to compute the hash of user account passwords. The function outputs a text string which also encodes the salt (usually the first two characters are the salt itself and the rest is the hashed result), and identifies the hash algorithm used (defaulting to the "traditional" one explained below).
A C implementation of a dynamically re-sizeable binary SHA-256 hash tree (Merkle tree) Merkle tree implementation in Java; Tiger Tree Hash (TTH) source code in C#, by Gil Schmidt; Tiger Tree Hash (TTH) implementations in C and Java; RHash, an open source command-line tool, which can calculate TTH and magnet links with TTH
The encryption process consists of updating the state with four round functions over 10 rounds. The four round functions are SubBytes (SB), ShiftColumns (SC), MixRows (MR) and AddRoundKey (AK). During each round the new state is computed as S = A K ∘ M R ∘ S C ∘ S B ( S ) {\displaystyle S=AK\circ MR\circ SC\circ SB(S)} .
Example of a Key Derivation Function chain as used in the Signal Protocol.The output of one KDF function is the input to the next KDF function in the chain. In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a ...
An AES instruction set includes instructions for key expansion, encryption, and decryption using various key sizes (128-bit, 192-bit, and 256-bit). The instruction set is often implemented as a set of instructions that can perform a single round of AES along with a special version for the last round which has a slightly different method.
