When to use cups and when to upgrade to TLS?
Using HTTPS (always on) as soon as a connection is established, and Using HTTP Upgrade to TLS (opportunistic) after the connection is established. CUPS supports self-signed, CA-signed, and enterprise certificates, with configurable certificate validation, cipher suite, and SSL/TLS version policies.
What are the encryption options in cups conf?
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. Security is reduced when Allow options are used. Security is enhanced when Deny options are used.
What are the options in client.conf ( 5 )-cups?
The AllowRC4 option enables the 128-bit RC4 cipher suites, which are required for some older clients. The AllowSSL3 option enables SSL v3.0, which is required for some older clients that do not support TLS v1.0. The DenyCBC option disables all CBC cipher suites.
What do you need to know about Cups?
Specifies the level of encryption that should be used. Specifies the Kerberos service name that is used for authentication, typically “host”, “http”, or “ipp”. CUPS adds the remote hostname (“[email protected]”) for you. The default name is “http”. Specifies the address and optionally the port to use when connecting to the server.
