While there isn’t much clarity, on how to enable “ssh-rsa” signature algorithm for user authentication, if it also gets disabled by default. It is possible that through thediscovery process, OpenSSH client may decide to use the deprecated algorithm. If that doesn’t happen, try the optio...
.RSA signatures with SHA-1 cannot be completely disabled in RHEL7 Because the `ssh-rsa` signature algorithm must be allowed in OpenSSH to use the new SHA2 (`rsa-sha2-512`, `rsa-sha2-256`) signatures, you cannot completely disable SHA1 algorithms in RHEL7. To work around this limitati...
