Thought to include a link to my updated version of Slacko5.7 by 01Micko. This dates from 09/2018 and has not been further updated. Atomic Pup found limits at OpenSSL 1.0.2p and wget at version 1.19.5 (do not load the 1.19.4 version). Firefox is 27.0.1, and is limited in today's internet. The certs for TLS1.2 ONLY need to be tweaked in about:config using the search term SSL. Only GCM 256 and 128 bit can be used... IIRC there's only 2 left that are good.
