Problem conclusion

• Resolution Summary:
  A code fix is provided.
  
  
  
  
  
  
  Fixed to return all SSH Known Host Keys through the REST API GET
  Known Host query. If there is an error with the loading a key,
  the error is reported in the Noapp Log, listing the SSH Key
  name:
  
  
  
  [2020-05-08 15:41:07.916] ALL 000000000000 GLOBAL_SCOPE Failed
  to load Public Key, record, knownhost_ssh1, Unable to parse key
  as format could not be identified.
  
  
  
  Also added validation of the saved Known Host Key, during the
  SSH Known Host Key creation, through the UI. If the Key cannot
  be retrieved and parsed successfully, the UI report an error to
  the dialog, when saving the Key:
  
  
  
  Unable to save the current object. Please contact your system
  administrator.
  
  
  
  The cause for this defect was when a RSA1 Type SSH Public Key
  was created through the UI. The SSHTools used by B2BI accepted
  the key, but interpreted its type incorrectly when parsing the
  key, resulting in errors if the Key was used, and resulting the
  empty brackets during the REST API call.
