EXAMPLE: Wrapping (obfuscating) a PL/SQL package body

plsql_wrapping_example.sql

-- Documentation: https://docs.oracle.com/en/database/oracle/oracle-database/18/lnpls/plsql-source-text-wrapping.html

-- One thing to keep in mind (that I didn't find in the docs) is that later, if you want to
-- update the variables in the package spec and re-compile the spec and the wrapped body, you can do
-- that in SQL Developer without having to re-wrap the original source code. Just open up
-- the wrapped body and click the Compile button.


-- Create package specification without obfuscation
create or replace PACKAGE HELLO_PKG AS
  g_person_to_greet varchar2(8) := 'Nate';
  procedure hello;
END HELLO_PKG;


-- Using the DBMS_DDL package is one way to wrap the body.
-- There's also command line utilities.
DECLARE
    l_str VARCHAR2(32000);
BEGIN
    l_str := q'~
CREATE OR REPLACE
PACKAGE BODY HELLO_PKG AS
  procedure hello AS
  BEGIN
    dbms_output.put_line('Hello ' || g_person_to_greet || '!');
  END hello;
END HELLO_PKG;~';
    dbms_ddl.create_wrapped(l_str);
END;
