The reason why this is a bug is, for example, that if the server was updated and it re-generated the ECDSA key you deleted, you would have to do some non-obvious steps for your client to ignore it.

hi folks: it looks like ssh-keygen -r can''t export SSHFP records for ECDSA keys: 0 dkg@pip:/tmp/cdtemp.oiRYAS$ ssh-keygen -f foobar -t ecdsa -q -P '''' 0 dkg@pip:/tmp/cdtemp.oiRYAS$ ssh-keygen -r foobar -f foobar.pub export_dns_rr: unsupported algorithm 0 dkg@pip:/tmp/cdtemp.oiRYAS$ the first number in my prompt is the return code of the last command; note that

Hi, I was sure I sent this to openssh at openssh.com, but cannot find that email now in my Sent mailbox, so I am sending it to the developers list. I took a liberty and wrote an I-D with accompanying patch (with contributions from Ondrej Caletka) to support ECDSA in the SSHFP DNS resource record. The I-D is here: https://tools.ietf.org/html/draft-os-ietf-sshfp-ecdsa-sha2 (and the source XML

Here you go: OpenSSH_7.9p1, OpenSSL 1.1.1d 10 Sep 2019 debug1: Reading configuration data /home/ryantm/.ssh/config debug1: /home/ryantm/.ssh/config line 4: Applying options for * debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 13: Applying options for * debug2: resolving "{REDACTED}" port 22 debug2: ssh_connect_direct debug1: Connecting to

Steps to reproduce: 1. Run a SSH server with default configuration and point a domain to it. 2. Add SSHFP record to the domain, but only for Ed25519 key. 3. Attempt to connect with VerifyHostKeyDNS set to yes, but the rest of settings set to defaults. 4. OpenSSH defaults to ECDSA instead of Ed25519 and refuses connection because there is no ECDSA fingerprint in SSHFP records. A stopgap solution
