I am running ubuntu 18.04.3 server HWE edition in my local lab and while reading the manuals I came across the issue that I am unable to determine how to exclude users from connecting to my server via ssh which do not use a key created using the ed25519 algorithm.
I know that I can configure sshd to deny specific ciphers, but I can not find information about restricting the usage of keys with specific algorithms.
I made it sofar that I basically deleted all host keys which are not ed25519 and restricted the renewal to only ed25519, but this obviously will not achieve what I want userside.
Thanks in advance.
