<p>The Hashing module provides one-way hashing functions. </p>
<p>Such functions can be used for creating a hash message authentication code (HMAC) when sending a message. Such a HMAC can be used in combination with a private key for authentication, which is a message integrity control.</p>
<p>All hash algorithms can be accessed via the generic MD layer (see <code><a class="el" href="md_8h.html#a7c956b5c92531111312324c91b6d83f9" title="Initialises and fills the message digest context structure with the appropriate values. ">md_init_ctx()</a></code>)</p>
<p>The following hashing-algorithms are provided:</p>
<ul>
<li>MD2, MD4, MD5 128-bit one-way hash functions by Ron Rivest (see <code><a class="el" href="md2_8h.html#a78e2af60e501496faa2639803bd6a923" title="Output = HMAC-MD2( hmac key, input buffer ) ">md2_hmac()</a></code>, <code><a class="el" href="md4_8h.html#a53e5896e59fcdcd68f842c579847dc79" title="Output = HMAC-MD4( hmac key, input buffer ) ">md4_hmac()</a></code> and <code><a class="el" href="md5_8h.html#a10b1ebaa2e129628989d59768ef58fd7" title="Output = HMAC-MD5( hmac key, input buffer ) ">md5_hmac()</a></code>).</li>
<li>SHA-1, SHA-256, SHA-384/512 160-bit or more one-way hash functions by NIST and NSA (see<code><a class="el" href="sha1_8h.html#a17ef720021c40b248d3ea69fe7373983" title="Output = HMAC-SHA-1( hmac key, input buffer ) ">sha1_hmac()</a></code>, <code><a class="el" href="sha256_8h.html#acdc08a6c1083b3a1ffb0bd5850272054" title="Output = HMAC-SHA-256( hmac key, input buffer ) ">sha256_hmac()</a></code> and <code><a class="el" href="sha512_8h.html#a97d975b27d9a1742e3bf7bdb00e3ecbb" title="Output = HMAC-SHA-512( hmac key, input buffer ) ">sha512_hmac()</a></code>).</li>
</ul>
<p>This module provides one-way hashing which can be used for authentication. </p>
