ripemd(3)                                          OpenSSL                                         ripemd(3)



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);

        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.

       RIPEMD16_() 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:

       RIPEMD16__Init() initializes a RIPEMD160_CTX structure.

       RIPEMD16__Update() can be called repeatedly with chunks of the message to be hashed (len bytes at
       data).

       RIPEMD16__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
       RIPEMD16_() returns a pointer to the hash value.

       RIPEMD16__Init(), RIPEMD16__Update() and RIPEMD16__Final() return 1 for success, 0 otherwise.

CONFORMING TO
       ISO/IEC 10118-3 (draft) (??)

       0.9.0.
