RIPEMD160, RIPEMD160_Init, RIPEMD160_Update, RIPEMD160_Final ā€” 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.
