Detailed Description

MD5 hash function implementation.

Function Documentation

av_md5_alloc()

struct AVMD5 * av_md5_alloc

(

void

)

Allocate an AVMD5 context.

Examples

filter_audio.c.

Referenced by main().

av_md5_init()

void av_md5_init

(

struct AVMD5 *

ctx

)

Initialize MD5 hashing.

Parameters

ctx	pointer to the function context (of size av_md5_size)

Examples

filter_audio.c.

Referenced by process_output().

av_md5_update()

void av_md5_update	(	struct AVMD5 *	ctx,
		const uint8_t *	src,
		size_t	len
	)

Update hash value.

Parameters

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

av_md5_final()

void av_md5_final	(	struct AVMD5 *	ctx,
		uint8_t *	dst
	)

Finish hashing and output digest value.

Parameters

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

av_md5_sum()

void av_md5_sum	(	uint8_t *	dst,
		const uint8_t *	src,
		size_t	len
	)

Hash an array of data.

Parameters

dst	The output buffer to write the digest into
src	The data to hash
len	The length of the data, in bytes

Examples

filter_audio.c.

Referenced by process_output().
