"Invalid Private Key Pass Phrase and Private key combination" error when importing RSA private key (4311146)

The key was loaded following these steps and an error "Invalid Private Key Pass Phrase and Private key combination" is reported

1). In the FMS console navigate to Administration | Credentials
2). Click Manage Credentials
3). Click Add and then select "RSA Key".
4). Load the private key from a file
5). Enter the Pass Phrase and User Name, and then click Next.

There could be multiple causes:

1) The wrong passphrase was used, double check.
2) The key was imported in RFC-4716 format. To check this, view the private key in a text editor. IF it looks like this:

---- BEGIN SSH2 ENCRYPTED PRIVATE KEY ----
Subject: foglight
Comment: "2048-bit rsa, foglight@*************, Tue Jun 26 2012 19:07:\
55 +0800"

Then the key is in RFC-4716 format, and the key should be in PEM format.

Private keys starting with "BEGIN OPENSSH PRIVATE KEY" and "BEGIN PRIVATE KEY" also indicate a different format is being used.

Please generate the key in PEM format and attempt to reload.

Note: If using OpenSSH to generate the key, not commercial SSH. If OpenSSH, cannot be used then generate a _unencrypted_ private key with commercial SHH and then that can be converted to the required PEM format. Save the key as a PEM file. OpenSSL does support PEM files using the -m flag.

Example:

ssh-keygen -t rsa -m PEM

This is what a PEM format key might look like:

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