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.
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()
do not return values.
