Ripemd-160 hash function
Usage
Crypto Library (libcrypto, -lcrypto)
#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(RIPEMD160_CTX *c, const void *data, unsigned long len);
int
RIPEMD160_Final(unsigned char *md, RIPEMD160_CTX *c);
Overview
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.
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 or 0 otherwise.
Caveats
Other implementations allow md in RIPEMD160() to be NULL and return a static array, which is not thread safe.
