 Caused by com.jcraft.jsch.JSchException:Auth fail

Below is the step-by-step scenario leading to the problem:

1. Configure your GIT repository with SSH Protocol
2. Download the GIT DMT extension
3. Open the DMT and run the GIT Packaging
4. It is failing at the Extraction step.

The issue occurs because of the format of the SSH key generated was not correct.

To solve the issue, you need to use the latest version of the GIT Extension and the private key generated by the below command line - 

$ ssh-keygen -m PEM -t rsa -b 4096

The format for the Private key should be like below. It should begin with "BEGIN RSA PRIVATE KEY"
