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);
int RIPEMD160_Init(RIPEMD160_CTX *c);
int RIPEMD160_Update(RIPEMD_CTX *c, const void *data,
unsigned long len);
int RIPEMD160_Final(unsigned char *md, RIPEMD160_CTX *c);
DESCRIPTION¶
RIPEMD-160 is a cryptographic hash function with a 160 bit output.
RIPEMD160() 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:
RIPEMD160_Init() initializes a
RIPEMD160_CTX structure.
RIPEMD160_Update() can be called repeatedly with chunks of the message to
be hashed (
len bytes at
data).
RIPEMD160_Final() 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
EVP_DigestInit(3) etc.
instead of calling the hash functions directly.
RETURN VALUES¶
RIPEMD160() returns a pointer to the hash value.
RIPEMD160_Init(),
RIPEMD160_Update() and
RIPEMD160_Final()
return 1 for success, 0 otherwise.
