Zelix KlassMaster - Java Obfuscator

Obfuscate References

A field or method reference is a field access or a method call. The following line of Java™ code represents references to the field System.out and to the method PrintStream.println(String).

System.out.println("Hello world");

A field or method reference can be to a Java™ API as in the example above or it can be to your own fields or methods. Zelix KlassMaster™'s Obfuscate References functionality allows you to obfuscate field or method references by replacing them with Reflection API calls. In the case of static field and method references, it also obscures the identity of the class containing the static member. Zelix KlassMaster™ then encrypts the names of the fields, methods and classes that are used by the Reflection API calls.

This allows you to selectively obscure field accesses and method calls in or to sensitive parts of your applications. It can make decompiled code quite incomprehensible. It can also obscure key API calls which otherwise would allow a hacker to "zero in" on a particular part of your bytecode.

Please see the Obfuscate References Tutorial for more detail.
