ssh.exe problem with keeagent #315

Closed madejusz closed 2 years ago

madejusz commented 3 years ago

Issue: ssh.exe can't get access to ssh keys C:\Users\test123> ssh-add -l error fetching identities: invalid format C:\Users\test123>

Software version: OS: Win10 ssh -V: OpenSSH_for_Windows_7.7p1, LibreSSL 2.6.5 Keepass: 2.48 (64bit) KeeAgent: 12.1

Configuration of KeeAgent: Cygwin/MSYS is set Enable agent for windows OpenSSH (experimental) - is on

Tested with SSH_AUTH_SOCK set to Cygwin socket and msysGit. Without success.

Putty.exe working pretty well.

What format are the keys? OpenSSH can't open PuTTY/Pagent keys.

madejusz commented 3 years ago

Keys created by ssh-keygen -t ed25519, attached to Keepass and loaded into agent. Work fine from Linux (and even under WSL v1/v2 with socat/npiperelay.exe trick). Putty.exe can read it to... but openssh-client from Win10 can't.

I had a similar issue. To fix it I converted the ppk to an openssl format key and then added that to keepass. Then removed the ppk from the key list in keeagent.

OpenSSH 7.7 was released April 3, 2018, so it probably can't handle keys that use newer formats. As a workaround you can change the keys to a different format that is supported by that version of OpenSSH or set the problematic keys to not load automatically.

Windows 11 has OpenSSH_for_Windows_8.1p1, LibreSSL 3.0.2, so hopefully this won't be a problem for most users going forward.

This isn't something we can fix in KeeAgent, so closing the issue.
