Detailed Description

Interface to a SHA-512 implementation.

Function Documentation

tinysha512_final()

void tinysha512_final	(	unsigned char *	digest,
		sha512_state *	s
	)

Computes the SHA-512 hash in the digest buffer.

Note

Assumes SHA512_DIGEST_SIZE bytes are available to accept the digest.

Warning

The state buffer 'leftover' is left in memory after processing. If your application intends to have sensitive data in this buffer, remember to erase it after the data has been processed

Parameters

[out]	digest	The computed digest. Must be non-null or behavior is undefined.
[in]	s	The hash state. Must be non-null or behavior is undefined.

tinysha512_init()

void tinysha512_init

(

sha512_state *

s

)

The SHA state.

Initializes the hash state

Parameters

[in,out]

s

The hash state to initialize.

tinysha512_update()

void tinysha512_update	(	sha512_state *	s,
		void const *	data,
		size_t	data_length
	)

Hashes data into state using SHA-512.

Warning

The state buffer 'leftover' is left in memory after processing. If your application intends to have sensitive data in this buffer, remember to erase it after the data has been processed

Parameters

[in,out]	s	The hash state. Must be non-null or behavior is undefined.
[in]	data	The data to hash into s.
[in]	data_length	The size of data in bytes.
