NAME
     RIPEMD160, RIPEMD160Init, RIPEMD160Update, RIPEMD160Final
     - RIPEMD-160 hash function

SYNOPSIS
      #include 

      unsigned char *RIPEMD160(const unsigned char *d, unsigned long n,
                       unsigned char *md);

      void RIPEMD160Init(RIPEMD160CTX *c);
      void RIPEMD160Update(RIPEMDCTX *c, const void *data,
                       unsigned long len);
      void RIPEMD160Final(unsigned char *md, RIPEMD160CTX *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
     RIPEMD160DIGESTLENGTH == 20 bytes of output). If md is
     NUL, the digest is placed in a static array.

     The following functions may be used if the message is not
     completely stored in memory:

     RIPEMD160Init() initializes a RIPEMD160CTX structure.

     RIPEMD160Update() can be called repeatedly with chunks of
     the message to be hashed (len bytes at data).

     RIPEMD160Final() places the message digest in md, which
     must have space for RIPEMD160DIGESTLENGTH == 20 bytes of
     output, and erases the RIPEMD160CTX.

     Applications should use the higher level functions
     EVPDigestInit(3) etc. instead of calling the hash functions
     directly.

RETURN VALUES
     RIPEMD160() returns a pointer to the hash value.

     RIPEMD160Init(), RIPEMD160Update() and RIPEMD160Final()
     do not return values.

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