ssh-audit (2.5.0-1) on debian 12

Following output suggestions "create a Github issue at https://github.com/jtesta/ssh-audit/issues":

"!!! WARNING: unknown algorithm(s) found!: [email protected]"

on kali-rolling,
deb package: openssh-server 1:9.6p1-4 amd64
default ssh_config, and custom rules based on ssh-audit output, for removing algorithms:

KexAlgorithms -ecdh-sha2-nistp256 -ecdh-sha2-nistp384 -ecdh-sha2-nistp521 -ecdsa-sha2-nistp256 -hmac-sha1 [email protected] -hmac-sha2-256 -hmac-sha2-512 [email protected] [email protected] [email protected] [email protected]

tnx!

The same algorithm is present in OpenSSH_7.9p1 Debian-10+deb10u4.

I also do only remove some algorithms from the config file:

KexAlgorithms -*sha1*,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256
