Cryptographic hash function wikipedia
WebJan 11, 2024 · A cryptographic hash function is a kind of hash function that has some additional security-related properties. Like in the general case, the input doesn't have to be the set of all bit-strings. Unlike the general case, though, it's rather uncommon to consider hash functions on structured input. WebA cryptographic hash function is a hash function, that is, an algorithm that takes an arbitrary block of data and returns a fixed-size bit string, the ( cryptographic) hash value, such that an (accidental or intentional) change to the data will (with …

WebThe NIST hash function competition was an open competition held by the US National Institute of Standards and Technology (NIST) to develop a new hash function called SHA-3 to complement the older SHA-1 and SHA-2.The competition was formally announced in the Federal Register on November 2, 2007. " NIST is initiating an effort to develop one or more … WebIn cryptography, cryptographic hash functions can be divided into two main categories. In the first category are those functions whose designs are based on mathematical problems, and whose security thus follows from rigorous mathematical proofs, complexity theory and formal reduction.

WebIt is one of the primary design objectives when people create a strong cipher or cryptographic hash function. They try to build a good avalanche effect in it. Mathematically this uses the butterfly effect. This is why most block ciphers are product ciphers. It is also why hash functions have large data blocks. Name [ change change source]
