Attention all Linux Mystic sysops who use cryptlib for SSH,

I've just managed to get 3.4.9.6 working with the newer ciphers - created a shim that translates session-attribute enum values (as Mystic has hardcoded them using the number lol).

If anyone wants to test, call my bbs via ssh on port 45022, and make sure that the "Allow AES128-CBC" is set to "No" - so you use the newer ciphers (thanks @Deuce for making SyncTERM the greatest!)

Mystic still sends data early, so the "Accept Early Data" needs to remain as "Yes" for the moment.

I made an installer too, so anyone who has Mystic v1.12 A49 (and maybe older versions) should be able to use my shim plus the latest version of cryptlib (as of today - newer will need an upgraded conversion table likely)

I think it could be useful for Mystic sysops - especially considering Mystic is now abandonware (or seemingly), having a more uptodate cryptlib and using newer ciphers keeps us safe and secure =)

Well done, good sir!

Thank you, I'm glad it works, even if Mystic has been abandoned by it's sole developer (apparently), we can still do "things" to keep it up to date of sorts.

I approve of this =)

One would hope that g00r00 would get some time to fix this, but it's been a while...
