remote-edit Uncaught Error: Cannot parse privateKey: Unsupported key format

update: using a PUTTY generated .ppy private key

I added a sftp host then did a 'Remote Edit Browse' command
selected the host that I previously added
it will try to connect and eventual time out while waiting for handshake
I created my private key the most generic way possible with PUTTY I don't know how it could be in an un-supported format to be honest. Also this same private key works for FileZilla SFTP connecting. this private key also works with sublime text sftp plugin.

Is it a putty or openssh style key? (what's the file ending)

May 16 '15 15:05 sveale

wow I really should have included that information sorry. It is PUTTY generated .ppy extension.

May 16 '15 16:05 JamesBedont

I don't know if that is supported by the underlying ssh library. According to this thread https://github.com/mscdex/ssh2/issues/191 it should be supported, but I'm not sure. I don't have access to a Windows machine at the moment. I think the easiest option would be to convert the key to an openssh style key.

Thanks I'll look into doing that.

May 16 '15 16:05 JamesBedont

after using PUTTYGEN to convert to an open ssh key I get the following error. I'm not sure if this is something you are concerned with but I felt like I may as well follow up.

Appreciate you letting me know :) Will take a look at it when it's convenient. Is the key protected by a passphrase? What specs were the key created with? (algorithm, length)

May 19 '15 12:05 sveale

Hey @sveale! I just caught the same exception on my Mac. It's probably my own fault—I'm using an Ed25519 key pair, which I imagine might have limited support—but thought I'd give you a heads-up anyway. I think the Sublime SFTP package and a number of other SFTP applications I use get around this kind of thing by going through the system ssh-agent—any chance that's a potential solution?

Jul 22 '15 16:07 phyllisstein

Hi @phyllisstein you can use ssh agent with this plug-in as well, just select "agent" as authentication method on your host. In regards to the exception it's really hard for me to test without the key. If you want you could create a dummy key pair of same configuration and upload it here and I could check it out. What makes this so hard is that the underlying ssh connection is handled by an entirely different package, ie. If the issue is with that package I don't have the expertise to do anything but file a bug :-)

Jul 22 '15 20:07 sveale

HAH! Oh my goodness, thank you for being so polite about pointing out that obvious oversight. "Agent" auth doesn't quite work on OS X, unfortunately:

My current best guess is that it's failing because the Atom process doesn't inherit the SSH_AUTH_SOCK envvar—if that's the case, I'll try to submit a PR in the next couple of days.

As for Ed25519, I've created a Gist with a throwaway keypair here: https://gist.github.com/phyllisstein/07fe1bee468ba92cb534. (If you wanna save some copy-pasting, you can grab the originals at https://cloudup.com/cN4xpjiyTBQ.) And no worries: I completely understand the aggravation of depending on third-party packages more capable than one's own.

Jul 22 '15 23:07 phyllisstein

@phyllisstein I think the issue here is that the underlying ssh module (ssh2) doesn't support Ed25519. I imagine that is why using an agent fails as well (this is just a guess).

Jul 25 '15 15:07 sveale

Just want to report that I have the same problem and I'm also using a Ed25519 with the auth method key. I' think we have to wait till ssh2 support it.

The tracking issue from there can you find here.
