Hi LaDidi,
you say: "Obfuscation is a good beginning.", exactly, a beginning... but i thought a little bit of advanced
Nitallica says: "if it run you can crack it". I know... i know
Actually, my idea was to use the hash of signed classes in jar file and create an hashtable to map some methods of some important classes.
Theory:
PHP Code:
Manifest-Version: 1.0
Created-By: 1.0
Name: license.class
SHA1-Digest: GLCkANwxP5fHNvDWMsjZDnHtPJg=
name: mainprog.class
SHA1-Digest: PFAwZkhDJwjBlYWxR4OT8FTx1NU=
name: another.class
SHA1-Digest: hZ5BVt7sHyG7rWYWm4eZVBXtfgY=
name: invoker.class
SHA1-Digest: UiJgkvDfAHhOJpg++oVYEGlCV9c=
main class methods:
calculate
save
Always in theory, if i use the license.class hash as a key to crypt the name of methods and i put it inside an hashtable of invoker.class and i call them
through it?
If you patch license.class the program flow is compromised...
What do you think about it?
Bye,
DaGoN
