Jenkins 1.651.1
SSH Agent 1.10
This is in a pipeline workflow...
It doesn't seem to be able to read the key, despite finding the credentials.

[JENKINS-35337] NPE from JNRRemoteAgent.addIdentity due to bad PEM format
I had the same problem (plugin version 1.13).
I think I got passed it when I enclosed the private key with the opening and closing statement:
-----BEGIN RSA PRIVATE KEY----- AAABARwm.... ...ggrkQs8= -----END RSA PRIVATE KEY-----
but then the error changed to:

needless to say that the sh 'ssh user@host' inside the sshagent scope fails.
UPDATE: ok, I used the complete ppk file and it works now. I guess the problem is just in the PEM format.
Close if https://github.com/jenkinsci/ssh-agent-plugin/pull/48 is merged.
Are you able to reproduce with the latest version of SSH Agent 1.11? This version now uses the Bouncycastle API and that part of the code has been reworked.
