I have a BigInteger value, let's say it is 282 and is inside the variable x. I now want to write a while loop that states:

while b2 isn't a perfect square:
    a ? a + 1
    b2 ? a*a - N
endwhile

How would I do such a thing using BigInteger?

EDIT: The purpose for this is so I can write this method. As the article states one must check if b2 is not square.

Why doesn't my implementation of El Gamal work for long text strings?

I'm playing with the El Gamal cryptosystem, and my goal is to be able to encipher and decipher long sequences of text. I have come up with a method that works for short sequences, but does not work for long sequences, and I cannot figure out why. El Gamal requires the plaintext to be an integer… >>> More

In Java, most of the primitive types are signed (one bit is used to represent the +/-), and therefore when I am exceed the limits of this type, I can get many strange things, like negative numbers.
