NAME
RIPEMD160, RIPEMD160_Init, RIPEMD160_Update, RIPEMD160_Final - RIPEMD-160 hash functionSYNOPSIS
#include <openssl/ripemd.h>
unsigned char *RIPEMD160(const unsigned char *d, unsigned long n,
unsigned char *md);
int RIPEMD160_Init(RIPEMD160_CTX *c);

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.
