  • The unwrap algorithm used in this SQL Developer extension is based on Niels Teusink’s Python script unwrap.py. The character substitution table is taken 1:1 from his source code, which he provided as public domain.
  • The following work helped me to understand the wrapping process:
    • David Litchfield’s The Oracle Hacker’s Handbook: Hacking and Defending Oracle (chapter 5)
    • Pete Finnigan’s How to Unwrap PL/SQL. Pete provides a lot of useful resources on his blog and has shown in this post, that he owns unwrappers for 9i and 10g, which should be capable to handle every wrapped code.
    • Anton Scheffler’s blog post about Unwrapping 10g wrapped PL/SQL
    • Automatic Detection of Vulnerabilities in Wrapped Packages in Oracle by Yaron Gur-Arieh, Nikita Zubrilov and Ilya Kolchinsky
    • Marcel Lambrechts’ blog about Unwrapping Wrapped PL/SQL in Oracle 10gR2 – 12cR1
