Description Alexander Sosedkin 2020-01-13 17:27:24 UTC
Version-Release number of selected component (if applicable): openssh-8.0p1-3.el8


CASignatureAlgorithms mentions in the manpages claim incorrect default values inherited from upstream.


Steps to reproduce: man ssh_config sshd_config


Actual results:

     CASignatureAlgorithms
             Specifies which algorithms are allowed for signing of certificates by certificate authorities (CAs).
             The default is:

                   ecdsa-sha2-nistp256.ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,
                   ssh-ed25519,rsa-sha2-512,rsa-sha2-256,ssh-rsa

             ssh(1) will not accept host certificates signed using algorithms other than those specified.


Expected results:

     CASignatureAlgorithms
             Specifies which algorithms are allowed for signing of certificates by certificate authorities (CAs).
             The default values are configured with crypto-policies(7).
             ssh(1) will not accept host certificates signed using algorithms other than those specified.


Additional info:

As the defaults are dynamic and governed by crypto-policies, we cannot really list them.
But even a passing mention of crypto-policies is better than a inaccurate list.
