How does DexGuard encrypt classes?

Question

I want to check how DexGuard works but it seems that it doesn\'t have a free trial version.

Can DexGuard encrypt an Android application? Or does it simply obfuscate

Answer 1

Although they use the term encryption, it seems that it is really obfuscation. I say this simply because although they may encrypt certain strings/values... the fact that the encryption key must also be stored in the app means that they are providing a "lock" for the code while at the same time packaging the "key" with it.
