Hash functions

Hash functions play an important role in many cryptographic and non-cryptographic mechanisms, for example when verifying data integrity or identifying files. They map a bit string m ∈ {0, 1}^* of arbitrary length to a bit string h ∈ {0, 1}ⁿ of fixed length n ∈ ℕ.

Jacksum 3.4.0 supports 472 hash functions, both cryptographic and non-cryptographic hash functions including CRCs and checksums.

The result of a hash function is the hash value.
