 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…

 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.
In the BigInteger class, I have no limits and there are some helpful functions there but it is pretty…

 I'm playing with numbers in Java, and want to see how big a number I can make. It is my understanding that BigInteger can hold a number of infinite size, so long as my computer has enough Memory to hold such a number, correct?
My problem is that BigInteger.pow accepts only an int, not another BigInteger…
