SecureKeys

A tiny lib (Less than 10 methods) to store constants where attackers will have a harder time to find.

This library uses an annotationProcessor to store the constants in a new file (where the constants are encrypted), and via JNI it will later retrieve them decoding them inside the .so file.

This way the attackers cant know the encoding system (because its inside the annotation processor), neither the decoding.
