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.
CONFORMING TO ISO/IEC 10118-3 (draft) (??) SEE ALSO sha(3) , hmac(3) , EVP_DigestInit(3) HISTORY RIPEMD160(), RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final()
are available since SSLeay 0.9.0.
