Key generation in the Signature Key Management is broken

Current Situation

When trying to create a private key and certificate for signing with the "generate public/private Key" feature in JOC Cockpit different error messages pop up depending on the selected key algorythm. After closing the modal window the newly generated key and certificate are present.

If no CA is present in the SSL Key Management only self signed certificates are created and these have all the same DNQ without reflecting the given JOC Cockpit user account.

Desired Behavior

When creating a private key and certificate for signing no error messages should pop up.

If no CA is present in the SSL Key Management the self signed certificates should have an unique DNQ reflecting the current JOC Cockpit user account in the CN entry of the DNQ.
