<!-- ==================== PACKAGE DESCRIPTION ==================== -->
<h1 class="epydoc">Package PublicKey</h1><p class="nomargin-top"></p>
<p>Public-key encryption and signature algorithms.</p>
<p>Public-key encryption uses two different keys, one for encryption and
one for decryption.  The encryption key can be made public, and the
decryption key is kept private.  Many public-key algorithms can also
be used to sign messages, and some can <em>only</em> be used for signatures.</p>
