Hi.. Any of you out there know of a bitReader()/bitWriter() class? I think this is where Java is lacking... Bit's... I eventually want to input a graphic file (bitmap), and encrypt it, then output back to a bitmap... If I could get bit input I could theoretically encrypt and then decrypt any data type out there... I want it... The technical aspects of INPUTTING a BITMAP (heh...) is a whole nother problem.. Any help would be appreciated. Or point me to a new programming language.

The term "bitmap" refers to the fact that the image isn't compressed. It corresponds bit-for-bit to the data displayed. You don't actually read/write individual bits. You can use the java.io.File*putStream classes to manipulate the files. Check out:
