Function Documentation

ha_blake2s_final()

HA_PUBFUN void ha_blake2s_final	(	ha_blake2s_context *	ctx,
		ha_digest_t	digest,
		size_t	digestlen )

Finalizes the BLAKE2s hash computation.

This function finalizes the hash and writes the output to the provided buffer.

Parameters

ctx	Pointer to the BLAKE2s context.
digest	Pointer to the output buffer (must be at least outlen bytes).
digestlen	Desired length of the hash output in bytes (1–32).

ha_blake2s_hash()

HA_PUBFUN void ha_blake2s_hash	(	ha_inbuf_t	data,
		size_t	len,
		ha_digest_t	digest,
		size_t	digestlen )

Computes the BLAKE2s hash of the input data.

This function performs a one-shot hash computation, initializing, updating, and finalizing the context in a single call.

Parameters

data	Pointer to the input data.
len	Length of the input data in bytes.
digest	Pointer to the output buffer (must be at least digestlen bytes).
digestlen	Desired length of the hash output in bytes (1–32).

ha_blake2s_init()

HA_PUBFUN void ha_blake2s_init

(

ha_blake2s_context *

ctx

)

Initializes the BLAKE2s hashing context.

Parameters

ctx	Pointer to the BLAKE2s context.

ha_blake2s_update()

HA_PUBFUN void ha_blake2s_update	(	ha_blake2s_context *	ctx,
		ha_inbuf_t	data,
		size_t	len )

Updates the BLAKE2s hash with input data.

This function processes the input data in blocks, updating the internal state.

Parameters

ctx	Pointer to the BLAKE2s context.
data	Pointer to the input data.
len	Length of the input data in bytes.
