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.

     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.
