Function Documentation

tinysha_digest_size()

size_t tinysha_digest_size

(

tiny_sha *

s

)

Returns size of digest depending on hash algorithm.

Parameters

[in]

s

The hash state. Must be non-null or behavior is undefined.

Returns

Size of digest

tinysha_final()

void tinysha_final	(	unsigned char *	digest,
		tiny_sha *	s
	)

Computes the hash algorithm in the digest buffer.

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.

tinysha_init()

void tinysha_init	(	HashAlg	sha_type,
		tiny_sha *	s
	)

Initializes the hash state.

Parameters

[in]	sha_type	Type of hash algorithm
[in,out]	s	The hash state to initialize.

tinysha_update()

void tinysha_update	(	tiny_sha *	s,
		void const *	data,
		size_t	data_length
	)

Hashes data into state using a chosen hash algorithm.

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.
