(Tcl) Socket Enable TLS 1.3

Chilkat supports TLS 1.3 starting in version 9.5.0.82. For this version, TLS 1.3 is not enabled by default. A program can enable TLS 1.3 by including the "EnableTls13" keyword in the UncommonOptoins property.

By activating TLS 1.3 support, Chilkat will send a TLS ClientHello that offers TLS 1.3 as an option to the server. It is the server that chooses the version of TLS to be used. Assuming the server chooses TLS 1.3, then TLS 1.3 will be the version of the TLS protocol used for the session.

Future versions of Chilkat will enable TLS 1.3 by default.

load ./chilkat.dll

set socket [new_CkSocket]

# To enable TLS 1.3, add the keyword "EnableTls13" to the UncommonOptions property.
# (TLS 1.3 will be enabled by default in future versions of Chilkat.)
CkSocket_put_UncommonOptions $socket "EnableTls13"

# With "EnableTls13" present, Chilkat will offer TLS 1.3 as a choice to the server for all TLS connections.
