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 nn bytes at dd
       and places it in mmdd (which must have space for RIPEMD160DIGESTLENGTH
       == 20 bytes of output). If mmdd 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:

       RIPEMD160Init() initializes a RRIIPPEEMMDD116600CCTTXX structure.

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

       RIPEMD160Final() places the message digest in mmdd, which must have
       space for RIPEMD160DIGESTLENGTH == 20 bytes of output, and erases the
       RRIIPPEEMMDD116600CCTTXX.

       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.
