Hash Functions

(hash/block-size hash-obj)

Return the block size of the `hash-obj`.

(hash/clear hash-obj)

Reset the state of `hash-obj` back to clean, as if no input has been supplied. Returns `hash-obj`.

(hash/copy hash-obj)

Return a new hash object copied from `hash-obj`. Returns new `hash-obj`.

(hash/final hash-obj)

Finalize the hash and return the output.

(hash/name hash-obj)

Return the name of the hash function.

(hash/new name)

Creates a hash of the given name, e.g., "SHA-384". Returns `hash-obj`.

(hash/output-length hash-obj)

Return the output length of the `hash-obj`.

(hash/security-level hash-obj)

Return the estimated security level of the `hash-obj` in bits, with respect to collision resistance. Returns zero for checksums.

(hash/update hash-obj input)

Add input to the hash computation. Returns `hash-obj`.
