- most of the old encryption ciphers (AES/128 bits, BF and 3DES) have been deprecated to encourage server operators to upgrade their security settings
- server logs will print a warning when user connect with a deprecated encryption cipher
- encryption support has been updated to comply with OpenSSL 1.1 and upper
- a « preferred cipher » setting has been added to 'etc/wired.conf' to give the ability to the administrator to accept only one unique cipher of their choice
Details about « preferred cipher » can be found here: https://github.com/nark/wired/blob/master/wired/wired.conf.in
