<div class="textblock"><p>Description: <a class="el" href="../../d8/d7c/class_o_n___m_d5.html">ON_MD5</a> is a small class for calculating the MD5 hash of a sequence of bytes. It may be use incrementally (the bytes do not have to be in a contiguous array in memory at one time).</p>
<p>Remarks: The <a class="el" href="../../d8/d7c/class_o_n___m_d5.html">ON_MD5</a> class cannot be used for cryptographic or security applications. The MD5 hash algorithm is not suitable for cryptographic or security applications. The <a class="el" href="../../d8/d7c/class_o_n___m_d5.html">ON_MD5</a> class does not "wipe" intermediate results.</p>
<p>The probability of two different randomly selected seqences of N bytes to have the same value MD5 hash depends on N, but it is roughly 2^-64 ~ 10^-19.</p>
<p>MD5 hash values are 16 bytes. SHA-1 hash values are 20 bytes. If you need a hash and have room for 20 bytes, then <a class="el" href="../../d8/df7/class_o_n___s_h_a1.html">ON_SHA1</a> is preferred over <a class="el" href="../../d8/d7c/class_o_n___m_d5.html">ON_MD5</a>.</p>
