NAME    [Toc]    [Back]

       RIPEMD160, RIPEMD160_Init, RIPEMD160_Update,
       RIPEMD160_Final - RIPEMD-160 hash function

LIBRARY    [Toc]    [Back]

       libcrypto, -lcrypto

SYNOPSIS    [Toc]    [Back]

        #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    [Toc]    [Back]

       RIPEMD-160 is a cryptographic hash function with a 160 bit

       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

RETURN VALUES    [Toc]    [Back]

       RIPEMD160() returns a pointer to the hash value.

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

CONFORMING TO    [Toc]    [Back]

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

HISTORY    [Toc]    [Back]

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