--- Comment #1 from Gordon Messmer <[email protected]> --- For example, I have an rsa-sha2-256 private key. If I connect to a server running openssh 7.4, and PubkeyAcceptedKeyTypes=ssh-rsa, then the key is correctly handled by the openssh 8.3 client. However, if PubkeyAcceptedKeyTypes=rsa-sha2-256, then the key cannot be used. The openssh 8.3 client accepts the same key and configuration when used to connect to openssh >= 7.8 servers. $ ssh-keygen -l -f ~/.ssh/id_rsa_2015-11-02 4096 SHA256:.... gordon (RSA) $ ssh -oPubkeyAcceptedKeyTypes=ssh-rsa -i ~/.ssh/id_rsa_2015-11-02 openssh74 Enter passphrase for key '/home/gordon/.ssh/id_rsa_2015-11-02': gordon@openssh74:~$ logout Connection to 192.168.122.11 closed. $ ssh -oPubkeyAcceptedKeyTypes=rsa-sha2-256 -i ~/.ssh/id_rsa_2015-11-02 openssh74 gordon@openssh74's password: gordon@openssh74:~$ logout Connection to 192.168.122.11 closed. $ ssh -oPubkeyAcceptedKeyTypes=rsa-sha2-256 -i ~/.ssh/id_rsa_2015-11-02 openssh78 Enter passphrase for key '/home/gordon/.ssh/id_rsa_2015-11-02': gordon@openssh78$ -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ openssh-bugs mailing list [email protected] https://lists.mindrot.org/mailman/listinfo/openssh-bugs
