Obfuscating PL/SQL Code With the wrap Utility

The wrap utility processes an input SQL file and obfuscates only the PL/SQL units in the file, such as a package specification, package body, function, procedure, type specification, or type body. It does not obfuscate PL/SQL content in anonymous blocks or triggers or non-PL/SQL code.

To run the wrap utility, enter the wrap command at your operating system prompt using the following syntax:

wrap iname=input_file [oname=output_file]

Note：Do not use any spaces around the equal signs.

input_file is the name of a file containing SQL statements, that you typically run using SQL*Plus. If you omit the file extension, an extension of .sql is assumed. For example, the following commands are equivalent:

wrap iname=/mydir/myfile
wrap iname=/mydir/myfile.sql

You can also specify a different file extension:

wrap iname=/mydir/myfile.src

output_file is the name of the obfuscated file that is created. The oname option is optional, because the output file name defaults to that of the input file and its extension defaults to .plb. For example, the following commands are equivalent:

wrap iname=/mydir/myfile
wrap iname=/mydir/myfile.sql oname=/mydir/myfile.plb

You can use the option oname to specify a different file name and extension:
wrap iname=/mydir/myfile oname=/yourdir/yourfile.out
