I'm trying to do a simple encryption/decryption program. The code below works fine if I never convert the encrypted text into a string. My problem occurs when i convert it to a string and then I convert it back into bytes. I want to eventually create a GUI, so I figured that if there is a encrypted text it will be assigned to a variable from a text field via a string. Please help if you can. Sorry for any confusion.

...

Can you please be more specific on how to exactly use the function?

Hello,

How do I find the probability under a normal distribution given a z-score in java? Do I use NormalDistribut ionImpl ? Or is there another function? I appreciate any help.
