TortoiseGit using incorrect SSH key

I have a strange problem with tortoise git at the moment, which I can't figure out. When trying to commit to my repository on github I get the error

ERROR: Permission to martindevans/Hermes.git denied to key2

Key2 is a key I use to access a different github repository, however the remote url is not set to use key2, as you can see here it's set to use private.ppk

enter image description here

Am I doing something obviously wrong, or is tortoise git broken?

Nb. In response to the comments. Using normal git results in:

C:\Users\Martin\Documents\Visual Studio 2010\Projects\Hermes>git push
Permission denied (publickey).
fatal: The remote end hung up unexpectedly

There are different private key formats. My keypair was generated with puttygen, but my Tortoise was configured to use ssh.exe (form msysgit) as ssh-client. So i changed it to plink (from Tortoise) and it worked.

  • ssh-key.exe => ssh.exe (C:\msysgit\msysgit\bin)
  • puttygen.exe => TortoisePlink.exe (C:\Program Files\TortoiseGit\bin)

Additional note: Use the correct URL! Github offers you three URL https, git and ssh.


I adapted the settings here:

Settings - TortoiseGit >> Network >> SSH-Client
C:\Program Files\TortoiseGit\bin\TortoisePLink.exe

I have generated the key-pair with:

 C:\Program Files\TortoiseGit\bin\puttygen.exe
