Description

 The CTL_SSL_CIPHER_SUITES option specifies one or more SSL/TLS 1.3 specific cipher suites to use for the control session between UEM components. The SSL/TLS protocol uses the cipher suites to specify which encryption and message authentication (or message digest) algorithms to use.

This option is specific to TLS 1.3. To configure ciphers for TLS 1.2 and earlier, see the ctl_ssl_cipher_list option.
