java.util.Random same across platforms?

[Evanstaul]

Maybe a dumb newbie question but its important for me.  I am making the scrambling algorithm for the CD-Key in my game.  Just wanted to verify that if I use java.util.Random and start it with a seed that it will be the same values across all platforms everywhere all the time?  There will be some nice complaints if I release a game and it wasn't the same.

Thanks!

If two instances of Random are created with the same seed, and the same sequence of method calls is made for each, they will generate and return identical sequences of numbers. In order to guarantee this property, particular algorithms are specified for the class Random. Java implementations must use all the algorithms shown here for the class Random, for the sake of absolute portability of Java code. However, subclasses of class Random are permitted to use other algorithms, so long as they adhere to the general contracts for all the methods.

From the JavaDoc - so yes, they will always generate the same sequence.
