ed25519 key auth fails with FileError about ssh2-python HOT 7 OPEN

Hi there,

Thanks for the interest and report.

This is a known issue with publickey_fromfile and ED25519 keys on Windows only. I suspect Window's file locking behaviour is the root cause.

Use userauth_publickey_frommemory instead to work around.

Does not work, same behavior. Any other suggestions?

from ssh2-python.

Yes, also tested.

I've not found a way to make ED25519 keys work on Windows clients. I'd suggest using ECDSA or any other type of key.

Can also use the high level client pssh.clients.ssh.SSHClient - documentation here.

Reference ParallelSSH/parallel-ssh#285

ED25519 key files cannot be loaded by neither userauth_publickey_fromfile nor userauth_publickey_frommemory on Windows clients only.

Most probably a bug with upstream libssh2. Needs C test case and tracing output to investigate and raise with libssh2.

Hello @pkittenis!
Any updates on this issue?

from ssh2-python.

Hello again, @pkittenis

It seems the issue was fixed in the latest version of libssh2. Is there a chance to update libssh2 on this repository as well?

from ssh2-python.

Pending new release of libssh2 that contains the fix.

1.10.0 is so far the latest version and it does not contain the fix.
