Hi,
I'm updating an application that uses TSQLConnector to connect to MySQL 5.7.
The MySQL server (5.7.42) will be restricted to use only TSLv1.2 (or
higher).
Is this possible with TSQLConnector ?
TLSv1.1 works without configuring anything.
With my test-server, it fails to connect when this is set to allow only
TLSv1.2.
The application will run on Windows 11 if that matters.
My libmysql.dll is version 5.7.42.0, in the same directory as the
application.
TSQLConnector will only pass on any connection parameters you set up to the
mysql layer.
If it fails for a particular TLS version, then I think it is more likely that
the libmysql.dll is too old (or the openssl lib that it uses) and does not
properly support TLSv1.2.
Michael.
