Description

The SSL_CIPHER_LIST option specifies one or more SSL/TLS cipher suites that UFTP would like to use to secure the control and data sessions for an FTPS transfer. 

This option is used only when the transfer protocol is FTPS.

Values

list is a comma-separated list of SSL/TLS cipher suites. The following table identifies the cipher suites supported for this option.

The list is in default order, with the most preferred suite first and the least preferred suite last.

Note

As of Universal Agent 6.7.0.0, DES-CBC-SHA is supported only on HP-UX.
 
Additionally, any Agents on HP-UX that accept connections from, or attempt connections to, Agents on other platforms must be configured with at least one currently supported cipher suite besides DES-CBC-SHA. Therefore, those HP-UX Agents cannot be configured only with DES-CBC-SHA in their list of cipher suites.
