SSL Protocol (-SPROTO)

Use the SSL Protocol adapter command (-SPROTO) to set the Secure Socket Layer (SSL) protocol level. SSL enables the adapter to process FTPS URLs. If -SPROTO is not specified, the SSL Protocol defaults to SSLv23.

This command is applicable only when the SSL secure_mode setting in the tx_install_dir\dtx.ini configuration file is set to 0 and RSA-based SSL encryption is in effect. This command is superseded by an SSL secure_mode setting of 1 or 2.


-SPROTO {SSLv2|SSLv3|SSLv23|TLSv1}
Option
Description
SSLv2
Specify SSL protocol version 2.
SSLv3
Specify SSL protocol version 3.
SSLv23
Specify SSL protocol version 2, version 3, TLSv1, TLSv1.1 or TLSv1.2.

Whenever the protocol method of SSLv23 is specified, the protocol of first choice is TLSv1.2, with fallback to TLSv1.1, then to TLSv1, then to SSLv3, and finally to SSLv2, depending on the GSKit module that is loaded.

TLSv1
Specify Transport Layer Security (TLS) protocol version 1.
