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
contextpointer to the function context (of size av_ripemd_size)
bitsnumber 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
contexthash function context
datainput data to update hash with
leninput data length

◆ av_ripemd_final()

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

Finish hashing and output digest value.

Parameters
contexthash function context
digestbuffer where output digest value is stored
