+<dd style="margin-left: 5.0em">Sets encryption options (only in /etc/cups/client.conf).
+By default, CUPS only supports encryption using TLS v1.0 or higher using known secure cipher suites.
+The <i>AllowRC4</i> option enables the 128-bit RC4 cipher suites, which are required for some older clients that do not implement newer ones.
+The <i>AllowSSL3</i> option enables SSL v3.0, which is required for some older clients that do not support TLS v1.0.
