RIPEMD160(3) — Subroutines

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.

The RIPEMD160() function 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:

The RIPEMD160_Init() function initializes a RIPEMD160_CTX structure.

The RIPEMD160_Update() can be called repeatedly with chunks of the message to be hashed (len bytes at data).

The RIPEMD160_Final() function 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 , such as EVP_DigestInit(), instead of calling the hash functions directly.

The ripemd() function conforms to ISO/IEC 10118-3 (draft).

RETURN VALUES

The RIPEMD160() function returns a pointer to the hash value.

The RIPEMD160_Init(), RIPEMD160_Update(), and RIPEMD160_Final() functions do not return values.

HISTORY

The RIPEMD160(), RIPEMD160_Init(), RIPEMD160_Update(), and RIPEMD160_Final() functions are available since SSLeay 0.9.0.
