General Purpose Hashing

Number of bytes in a generic, simple hash.

Maximum number of bytes allowed when creating a keyed hash.

Minimum number of bytes allowed when creating a keyed hash.

Number of bytes required in context buffer for hashing.

(hash/final state len)

Get the final hash after digesting all of the input as a string. The resulting hash will be a string of length len.

(hash/hash size input ctx &opt key)

Hash some input bytes into an output string of length size. Optionally provide a key that can be used to generate different hashes on the same input.

Number of bytes in a key required for hashing.

(hash/keygen &opt buf)

Generate a key suitable for use in hashing. The key is a buffer of at least 32 bytes. If a buffer buf is provided, the first 32 bytes of buf will be set to a new random key. Returns a key buffer.

(hash/new-state ctx key)

Create a new hash-state. Takes a context ctx and a key and returns a new abstract type, jhydro/hash-state. Both ctx and key should be byte sequences, of at least lengths 8 and 32 respectively. Returns the new state.

(hash/update state bytes)

Add more bytes to the hash state. Returns the modified state
