description:
Fix a problem with overrunning a base64 decoded number when decoding ssh
keys, from Anthony Bentley.

        % netpgpkeys --ssh -l --hash=md5
        1 key found
        signature  1024/RSA (Encrypt or Sign) 666f47feddcdb77d 2002-07-02
        Key fingerprint: e1d6 b328 8126 e8e3 666f 47fe ddcd b77d
        uid              machinename.com (/home/user/.ssh/id_rsa.pub) <user%machinename.com@localhost>

        % ssh-keygen -l -f ~/.ssh/id_rsa.pub
        1024 e1:d6:b3:28:81:26:e8:e3:66:6f:47:fe:dd:cd:b7:7d /home/user/.ssh/id_rsa.pub (RSA)
