Attached describes the values used that worked for me:
Steps for the private key here:
•Take the value for the private key within quotes and put it in a text editor.
•Since this is a single line, use text editor (or manually) to replace “\r\n” with a new line key
•Save it in a file eg: aemassets.key
•Run the following “openssl” command to convert the RSA key to pkcs8 not encrypted value:
“openssl pkcs8 -topk8 -nocrypt -in aemassets.key -out aemassets.pkcs8.key”
•Use the value from the above command in file aemassets.pkcs8.key in the “Private Key” field to make the connection.
•Please note that there are other options when clicking the “Extract” button that might help as well
