AES Encryption of byte array

2011-03-01 Thread Meszaros, Stacy
Hello all, I am very new to python, using it to write a test application. I need to be able to encrypt part of a byte array (up to 256 bytes where the first 7 bytes remain plain text) using AES 128 bit CBC encryption. I am using Python 2.6, can anyone recommend a toolkit or module? Thanks, Stac

Ere, I mean testing only symetrical keys, and symetrical messages, nothing more realistic. Sigh. Oh well. It works, and that's the important thing. I don't know if I'll put in support for the larger key sizes, but, I'll leave it be for now. -- http://mail.python.org/mailman/listinfo/python-list

Okay, I figured out the problem. The problem was that my algorythm filed the numbers into the matrix as so: 1 2 3 4 5 6 7 8... While it should have been 1 5 9 13 2 6 10 14 ... When this was fixed, the program works great! That's what I get for testing only asymetrical keys... Oh well, thanks for

I don't know if it means anything, but the AES system that I have isn't set up to do anything other than 128 bit encryption at the moment, nor will it likely do so, mainly because most systems only explain how to get the 128 encryption, and not the larger sizes. I'm sure it's fairly easy to change,

I have just finished a new function that will do AES128 encryption, which is the standard for private-key cryptology today. In fact, the NSA permitted AES to be used for classified documents in the USA, the first time a public algorithm has been given this honor (Secret and Top Secret documents can
