<p>All of the functions described on this page are deprecated.

<p>RIPEMD-160 is a cryptographic hash function with a 160 bit output.</p>
|
||
|
|
|
||
|
|
<p>RIPEMD160() computes the RIPEMD-160 message digest of the <b>n</b> bytes at <b>d</b> and places it in <b>md</b> (which must have space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output). If <b>md</b> 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 <b>RIPEMD160_CTX</b> structure.</p>
|
||
|
|
|
||
|
|
<p>RIPEMD160_Update() can be called repeatedly with chunks of the message to be hashed (<b>len</b> bytes at <b>data</b>).</p>
|
||
|
|
|
||
|
|
<p>RIPEMD160_Final() places the message digest in <b>md</b>, which must have space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases the <b>RIPEMD160_CTX</b>.</p>

<p>RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() return 1 for success, 0 otherwise.</p>
