If you enable "shadow directory" (RME - Admin - Config Mgmt - Archive Mgmt - Archive Settings), you can find the raw configs in locations such as /var/adm/CSCOpx/files/rme/dcma/shadow/Security_and_VPN/PRIMARY on Solaris, or its Windows equivalent, after one requisite cycle of Periodic Polling and/or Periodic Collection. That's the same config one'd get saving to TFTP manually.
However, I don't recall how to unscramble the "asterisks" in the RME GUI, if at all possible.
