HI @manojfim

You do include the first and the last line of your key in key store?:

-----BEGIN RSA PRIVATE KEY-----

and this:

-----END RSA PRIVATE KEY-----

Also, make sure that you're using the JSch supported ciphers:

Thanks for responding so quickly. I was using OPENSSH format key. when i switched to RSA it worked.

In case anyone comes here looking for this answer, ssh-keygen -p -m PEM -f /path/to/openssh/key will re-write the private key in the correct format.
