BI and AI files are encrypted by default. You can disable their encryption, but doing so is highly discouraged because data can be exposed in an unencrypted form in your BI and AI notes. Backup files are always encrypted. Binary dump (and audit archive) files are not encrypted by default, even if the data being dumped is encrypted. You can encrypt your dump files with a password based encryption (PBE) cipher by adding an additional parameter to the command. If you intend to keep your dump or archive for an extended period of time, encrypting it may be prudent. For more information about encrypting a dump file, see
PROUTIL Utility.
