RIPEMD160(3)RIPEMD160(3)NAME
RIPEMD160, RIPEMD160_Init, RIPEMD160_Update, RIPEMD160_Final-
RIPEMD-160 hash function
SYNOPSIS
#include <openssl/ripemd.h>
unsigned char *RIPEMD160(
const unsigned char *d, unsigned long n,
unsigned char *md ); void RIPEMD160_Init(
RIPEMD160_CTX *c ); void RIPEMD160_Update(
RIPEMD_CTX *c, const void *data, unsigned
long len ); void RIPEMD160_Final(
unsigned char *md, RIPEMD160_CTX *c );
DESCRIPTION
RIPEMD-160 is a cryptographic hash function with a 160 bit output.
The RIPEMD160() function computes the RIPEMD-160 message digest of the
n bytes at d and places it in md (which must have space for
RIPEMD160_DIGEST_LENGTH == 20 bytes of output). If md is NULL, the
digest is placed in a static array.
The following functions may be used if the message is not completely
stored in memory:
The RIPEMD160_Init() function initializes a RIPEMD160_CTX structure.
The RIPEMD160_Update() can be called repeatedly with chunks of the mes‐
sage to be hashed (len bytes at data).
The RIPEMD160_Final() function places the message digest in md, which
must have space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and
erases the RIPEMD160_CTX.
Applications should use the higher level functions , such as EVP_Diges‐
tInit(), instead of calling the hash functions directly.
The ripemd() function conforms to ISO/IEC 10118-3 (draft).
RETURN VALUES
The RIPEMD160() function returns a pointer to the hash value.
The RIPEMD160_Init(), RIPEMD160_Update(), and RIPEMD160_Final() func‐
tions do not return values.
HISTORY
The RIPEMD160(), RIPEMD160_Init(), RIPEMD160_Update(), and
RIPEMD160_Final() functions are available since SSLeay 0.9.0.
