Can you give me some advice on a good reduction function for rainbow table hashes to implement in java?
The reduction functions I saw in C++ mostly used unsigned 64bit integer what Java isn’t capable of natively now and I’d like to find another solution. (Should be available at Java 8.)
Alternatively: If someone knows a library in Java that supports the – at least not inefficient – usage (and maybe cration) of rainbow tables, please tell me. Would be great not to implement that on my own.
Sadly I’m bound to Java as a platform so I can not use the good C++ implementations on the market.
If the algorithm you used consists of additions, subtractions, multiplications and bitwise operations, it is an easy matter to translate it to work with Java
longinstead of unsigned.
