Detailed Description

RIPEMD hash function implementation.

Function Documentation

av_ripemd_alloc()

struct AVRIPEMD * av_ripemd_alloc

(

void

)

Allocate an AVRIPEMD context.

av_ripemd_init()

int av_ripemd_init	(	struct AVRIPEMD *	context,
		int	bits
	)

Initialize RIPEMD hashing.

Parameters

context	pointer to the function context (of size av_ripemd_size)
bits	number of bits in digest (128, 160, 256 or 320 bits)

Returns

zero if initialization succeeded, -1 otherwise

av_ripemd_update()

void av_ripemd_update	(	struct AVRIPEMD *	context,
		const uint8_t *	data,
		size_t	len
	)

Update hash value.

Parameters

context	hash function context
data	input data to update hash with
len	input data length

av_ripemd_final()

void av_ripemd_final	(	struct AVRIPEMD *	context,
		uint8_t *	digest
	)

Finish hashing and output digest value.

Parameters

context	hash function context
digest	buffer where output digest value is stored
