DATA_SSL_CIPHER_SUITES - UCMD Server configuration option
Description
The DATA_SSL_CIPHER_SUITES option specifies one or more SSL/TLS 1.3 specific cipher suites that are acceptable to use for network communications on the data session, which is used for standard I/O file transmission.
This option is specific to TLS 1.3. To configure ciphers for TLS 1.2 and earlier, see the data_ssl_cipher_list option.

Values
cipherlist is a comma-separated list of SSL/TLS cipher suites. The following table identifies the list of SSL/TLS cipher suites supported for this option.
The list is in default order, with the most preferred suite first and the least preferred suite last.
If the SSL implementation is System SSL, the order of the list does not indicate preference.
Cipher Suite | Description |
|---|---|
TLS_AES_256_GCM_SHA384 | 256-bit AES encryption in Galois Counter Mode, SHA-2 384-bit message digest |
TLS_CHACHA20_POLY1305_SHA256 | 256-bit CHACHA encryption with POLY1305 message authentication, SHA-2 256-bit message digest |
TLS_AES_128_GCM_SHA256 | 128-bit AES encryption in Galois Counter Mode, SHA-2 256-bit message digest |
