cipher
Access: Super User, Administrator
Description: Enable or disable cryptographic algorithms for Web UI sessions. You cannot enable or
disable these algorithms directly from the Web UI. You must reboot your appliance after enabling or
disabling algorithms for changes to take effect.
There are three categories of algorithms: Authentication algorithms, Block Cipher algorithms, and MAC
algorithms. Available and Blocked Cipher Suites are also listed.
NOTE: Disabling the only algorithm will block all SSL/TLS sessions.
NOTE: The status of an algorithm is toggled when the cipher command is executed. It is recommended
that you check the status of an algorithm before enabling or disabling it.
Parameters:
Example 1: Disable the triple-DES block cipher.
