<p>RIPEMD160, RIPEMD160_Init, RIPEMD160_Update, RIPEMD160_Final -
RIPEMD-160 hash function</p>

<h1><a name="description">DESCRIPTION</a></h1>
<p>RIPEMD-160 is a cryptographic hash function with a
160 bit output.</p>
<p>RIPEMD160() computes the RIPEMD-160 message digest of the <strong>n</strong>
bytes at <strong>d</strong> and places it in <strong>md</strong> (which must have space for
RIPEMD160_DIGEST_LENGTH == 20 bytes of output). If <strong>md</strong> is NULL, the digest
is placed in a static array.</p>
<p>The following functions may be used if the message is not completely
stored in memory:</p>
<p>RIPEMD160_Init() initializes a <strong>RIPEMD160_CTX</strong> structure.</p>
<p>RIPEMD160_Update() can be called repeatedly with chunks of the message to
be hashed (<strong>len</strong> bytes at <strong>data</strong>).</p>
<p>RIPEMD160_Final() places the message digest in <strong>md</strong>, which must have
space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases
the <strong>RIPEMD160_CTX</strong>.</p>
<p>
</p>
<hr />
<h1><a name="return_values">RETURN VALUES</a></h1>
<p>RIPEMD160() returns a pointer to the hash value.</p>
<p>RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() return 1 for
success, 0 otherwise.</p>
<p>
</p>
<hr />
<h1><a name="note">NOTE</a></h1>
<p>Applications should use the higher level functions
<em>EVP_DigestInit(3)</em> etc. instead of calling these
functions directly.</p>
