Detailed Description

Header file for the BLAKE2b hashing algorithm.

This file provides the interface for the BLAKE2b cryptographic hash function. It includes the definition of the hash state context and function declarations for initializing, updating, finalizing, and computing the hash in a one-shot operation. BLAKE2b is optimized for 64-bit platforms and offers high security and performance.

Function Documentation

ha_blake2b_final()

HA_PUBFUN void ha_blake2b_final	(	ha_blake2b_context *	ctx,
		ha_digest_t	digest,
		size_t	digestlen )

Finalizes the BLAKE2B hash and produces the digest.

Parameters

ctx	Pointer to the initialized BLAKE2B context.
digest	Pointer to the output buffer where the hash will be stored.
digestlen	Desired length of the output hash (1 to 64 bytes).

ha_blake2b_hash()

HA_PUBFUN void ha_blake2b_hash	(	ha_inbuf_t	data,
		size_t	len,
		ha_digest_t	digest,
		size_t	digestlen )

Computes the BLAKE2B hash in a one-shot operation.

This function initializes a BLAKE2B context, processes the input data, and finalizes the hash computation, storing the result in the provided buffer.

Parameters

data	Pointer to the input data.
len	Length of the input data in bytes.
digest	Pointer to the output buffer where the hash will be stored.
digestlen	Desired length of the output hash (1 to 64 bytes).

ha_blake2b_init()

HA_PUBFUN void ha_blake2b_init

(

ha_blake2b_context *

ctx

)

Initializes a BLAKE2B context.

Parameters

ctx	Pointer to the BLAKE2B context to initialize.

ha_blake2b_update()

HA_PUBFUN void ha_blake2b_update	(	ha_blake2b_context *	ctx,
		ha_inbuf_t	data,
		size_t	len )

Updates the BLAKE2B hash state with input data.

Parameters

ctx	Pointer to the initialized BLAKE2B context.
data	Pointer to the input data.
len	Length of the input data in bytes.
