    <title>Description</title>

    <para><command>genkey</command> is an interactive command-line
    tool which can be used to generate SSL certificates or Certificate
    Signing Requests (CSR).  Generated certificates are stored in the
    directory <filename>/etc/pki/tls/certs/</filename>, and the
    corresponding private key in
    <filename>/etc/pki/tls/private/</filename>. </para>

    <para><command>genkey</command> will prompt for the size of key
    desired; whether or not to generate a CSR; whether or not an
    encrypted private key is desired; the certificate subject DN
    details.</para>

    <para><command>genkey</command> generates random data for the
    private key using the truerand library and also by prompting the
    user for entry of random text.</para>
