I'm using twisted 20.3 and python3.6.8 and Windows 10 I'm using endpoint_description with a tac file to start up a server.
But I need to disable tls 1.0 and 1.1. I was hoping to find a parameter I could pass in to make the system only recognise 1.2 and 1.3. But could not find anything that would do that. I thought sslmethod would be what I wanted but that is limited to : Must be one of: "SSLv23_METHOD", "SSLv2_METHOD", "SSLv3_METHOD", "TLSv1_METHOD". If I choose TLSv1_METHOD, TLS1.0 and 1.1 are still enabled and QUALYS complains and downgrades the rating to B In the end I found _defaultMinimumTLSVersion in _sslverify.py. I set this to TLSVersion.TLSv1_2 and that seemed to do the trick. But I don't think I should be doing that. I think I've missed some obvious place where I can pass in a value to change this. Anyone know where I should be looking. Thanks for any info -- *John Aherne* *www.rocs.co.uk <http://www.rocs.co.uk>* 020 7223 7567
