The following tables compare general and technical information for a number of cryptographic hash functions. See the individual functions' articles for further information. This article is not all-inclusive or necessarily up-to-date. An overview of hash function security/cryptanalysis can be found at hash function security summary.
Extendable-output function (XOF) is an extension [1] of the cryptographic hash that allows its output to be arbitrarily long. In particular, the sponge construction makes any sponge hash a natural XOF: the squeeze operation can be repeated, and the regular hash functions with a fixed-size result are obtained from a sponge mechanism by stopping the squeezing phase after obtaining the fixed ...
Most cryptographic hash functions are designed to take a string of any length as input and produce a fixed-length hash value. A cryptographic hash function must be able to withstand all known types of cryptanalytic attack. In theoretical cryptography, the security level of a cryptographic hash function has been defined using the following ...
In cryptography and computer security, a length extension attack is a type of attack where an attacker can use Hash(message 1) and the length of message 1 to calculate Hash(message 1 ‖ message 2) for an attacker-controlled message 2, without needing to know the content of message 1.
In cryptography, MDC-2 (Modification Detection Code 2, sometimes called Meyer–Schilling, [citation needed] standardized in ISO 10118-2) is a cryptographic hash function. MDC-2 is a hash function based on a block cipher with a proof of security in the ideal-cipher model. [1] The length of the output hash depends on the underlying block cipher ...
Knapsack-based hash functions—a family of hash functions based on the knapsack problem. The Zémor-Tillich hash function—a family of hash functions that relies on the arithmetic of the group of matrices SL 2. Finding collisions is at least as difficult as finding factorization of certain elements in this group.
The SHA-3 NIST hash function competition concerned general-purpose designs and focused on software performance. Quark is a lightweight hash function, based on a single security level and on the sponge construction, to minimize memory requirements. Inspired by the lightweight ciphers Grain and KATAN, the hash function family Quark is composed of ...
