Data Fields
void(*	init )(void)
	Starts a hash session.
void(*	update )(const uint8_t *data, size_t len)
	Processes a chunk of data.
void(*	finalize )(uint8_t digest[static 32])
	Terminates the hash session and produces the digest.
void(*	create_checkpoint )(sha_256_checkpoint_t *checkpoint)
	Saves the hash session, e.g., before pausing a protothread.
void(*	restore_checkpoint )(const sha_256_checkpoint_t *checkpoint)
	Restores a hash session, e.g., after resuming a protothread.
void(*	hash )(const uint8_t *data, size_t len, uint8_t digest[static 32])
	Does init, update, and finalize at once.

Field Documentation

finalize

void(* sha_256_driver::finalize) (uint8_t digest[static 32])

Terminates the hash session and produces the digest.

Parameters

digest

pointer to the hash value

Definition at line 87 of file sha-256.h.

hash

void(* sha_256_driver::hash) (const uint8_t *data, size_t len, uint8_t digest[static 32])

Does init, update, and finalize at once.

Parameters

data	pointer to the data to hash
len	length of the data to hash in bytes
digest	pointer to the hash value

Definition at line 105 of file sha-256.h.

update

void(* sha_256_driver::update) (const uint8_t *data, size_t len)

Processes a chunk of data.

Parameters

data	pointer to the data to hash
len	length of the data to hash in bytes
