CHANGE_ENCRYPTION_ON_COMPACT <YES | NO>
Allows changing the encryption attributes of a file using the compact API function.
If an encrypted file is compacted, the resulting file will be encrypted using the same method.
Note: Setting this keyword to YES allows a user to permanently decrypt a file without knowing the master encryption key.
In V11 and later, to change the encryption attributes of a file using the compact function from a client, add the CHANGE_ENCRYPTION_ON_COMPACT YES to ctsrvr.cfg. If this keyword is not present or set to No, the operation fails with error NSUP_ERR (454, not supported).
