Custom Provider - OpenSSL 3.x with SSHD

[Tomas Mraz]

The primary question is, does your provider just implement some of the
existing algorithms that the OpenSSH supports or do you want to add a
new cipher algorithm? If the second, then OpenSSH needs to be patched
to add support for the new algorithm. I do not think it supports custom
pluggable algorithms.
