SSL_CIPHER_LIST - UFTP configuration option

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.

Usage

Method	Syntax	IBM i	HP NonStop	UNIX	Windows	z/OS

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.
