Stringer Java Obfuscator 1.6.7 (St. Patrick) Released

Good news everyone!
We have just released the new version of Stringer. There are a lot of improvements in it, and the main one is Java 8 bytecode support. Now Stringer can generate bytecode of specified version. So you can easily convert your program to use Java 7 or Java 8 bytecode format without recompiling. Using Java 7 or 8 bytecode format you can utilize the full power of Integrity Protection made with use of indy instruction, which makes you classes "non-decompilable" with popular Java decompilers. For your convenience we added support for ProGuard's map files, thus you can set original class names in filters.


  • Added support for Java 8 bytecode
  • Added ability to use ProGuard’s map files, in order to use original class names to be set in Stringer’s filters
  • Added ability to force version of bytecode
  • Multiple String protection functions per package
  • Enhanced Resource encryption function
  • Improved Hide API mechanism, while using Integrity Protection

If you have any questions just let us know.

Have a great St. Patrick's day!
