Using Encrypted Files
Provided that you have a compatible version of the software then encrypted files can be read transparently in all modules that include PML.
11.5.SP2 and 11.6.SP4 versions released before January 2008 support an "Early Adopter" encryption type 3, which is no longer supported from the first full release of PML Publisher 1.0. AVEVA released updated versions 11.5.SP2.11 and 11.6.SP4.9 supporting the replacement encryption type 4, which is also supported in AVEVA 12-series and later 11.5-series and 11.6-series releases.
If you have existing encrypted files encrypted with encryption type 3, you must re-encrypt the original source to encryption type 4 if you wish to use them with versions 12.0, 11.6.SP4.9, 11.5.SP2.11 and later releases.
If you attempt to display or record encrypted PML using the $R commands, you will find that all lines are replaced by the text <hidden>. Error messages and trace-backs will include function names, but not the text of each line.
The only circumstance in which hidden lines can become visible is under certain circumstances during a macro which includes a module-switch. After a module switch, any remaining lines in that macro may or may not be traceable. This may change in a future release.
