WinCrypt not working anymore as pageant #385

Closed brain246 closed 1 year ago

brain246 commented 1 year ago

Hello there,

I have been (and am still) using the combination of KeePass, KeeAgent (client mode) and WinCrypt for storing and serving any ssh keys for a while now. The reason for using Wincrypt as pageant was because it has good compatibility with WSL2.

After getting a new notebook and reinstalling everything however, i am getting this error message when trying to add ssh keys: image (just removed the entry name in line 2)

It works fine if i am using Putty's pageant though, so this might entirely be an issue with Wincrypt as well. I downgraded KeeAgent and WinCrypt to the exactly same versions as i am using them on the other machine, the issue remains though.

Any ideas on how to approach this any further?

The full error message:

See the end of this message for details on invoking

I fixed the issue myself or more like found a workaround: After starting KeePass/KeeAgent with admninistrator privileges everything works again.

dlech commented 1 year ago

Since you are using client mode, I don't think there is anything we can do in KeeAgent. I'm guessing you are running Pagent as an admin?

That's the odd thing: I am not running the pageant as admin. But the company policies and the way they handle local admin privileges (my user isn't admin per se anymore, but can request admin privileges for certain actions/processes) seems to make a difference here. But it is working now, so you can close this issue, maybe it is of some help for others in the future though.

Thanks for the fast response and have a nice day (or evening wherever you are) :)

Just wanted to add something here: In fact i was running WinCryptAgent with admin privileges (that was set in the exe properties -> advanced, i somehow had forgotten that). The issue was however, that when not running it with admin rights, KeeAgent wasn't able to add the keys to the agent (same thing happened by the way with putty/pageant).

In the end i ended up using KeeAgent in Agent mode (with OpenSSH enabled) and the WSL2 part i solved with npiperelay.exe and wsl-ssh-agent-relay as described here.

That works now in any Windows Shell, WSL2 (Bash and Fish) and also in Git-Bash (Git for Windows).
