SSH passphrase, supported encryption protocols

Dear

Using Pipeline Pilot 2017 (17.2.0.1361), I would like to use an encrypted ssh key to log into a remote machine.

I generated this key with the standard ssh-keygen command, after transferring the key to the pipeline pilot protocol and entering the passphrase, the following error was reported:


Invalid passphrase for Key File.

This doesn't make sense, since I am able to log into the machine using this key and passphrase. Could it be that the Pipeline Pilot server does not support the used encryption? The ssh key was encrypted with AES-128-CBC and a proc-type of 4. 

Does Pipeline Pilot 2017 (17.2.0.1361) support an AES-128-CBC encrypted ssh key?
