Class Obfuscate

java.lang.Object

asia.redact.bracket.properties.Obfuscate

public final class Obfuscate
extends Object

 Support for obfuscated properties. 
 
 This is essentially encryption. However, because the code below is open-sourced, you should not
 use it as a security feature, merely an obfuscation to make reading the values in place more difficult.
 
 To make it into a security feature, you can add a salt file which will in essence alter the key derivation
 to become private to your installation.
 
 Just put a file called "salt.txt" into the home folder or the top of the classpath with the following contents:
 
 salt=xxxx
 
 where xxxx is some random string of any non-zero length. It will be added as salt. Note: if you do this,
 your obfuscated file data is no longer portable, at least not without some effort.
