<code>authcert</code> - DES validation program
</h3><hr>
<p><h4>Synopsis</h4>
<p><code>authcert</code>
<p><h4>Description</h4>
<p>This program verifies whether the DES encryption algorithm is
operating correctly in the particular architecture. The program reads a
line from the standard input containing a key, plaintext block and the
corresponding encrypted ciphertext block, respectively, as in the
following
