AES 128-bit compression in GNU-C/Python

Budget is $50

An AES (Rijndael algorithm) 128-bit compression implementation using the "counter mode", not the cipher mode.

Requirements:

- One Javascript implementation that can run in IE, FireFox or Opera

- One GNU-C/Python implementation to run in a RedHat Linux environment

- encode/decode encrypted raw AES data into base64 to allow easy exchange and transfer of data

- Browser Javascript and Server Python implementations are to be totally compatible. ie, AES/base64 encryption from server Python should be able to be decrypted by Javascript version. Similarly, Javascript encryption should be decryptable via the server Python program.

- The following Javascript implementation will be sufficient for AES 128-bit: <[url removed, login to view]>

But this doesn't do base64 encoding. That needs to be added.

- The following C/Python implementation is similar to what I need, but it does not seem to be compatible with the Javascript implementation of the previous point:

<[url removed, login to view]>

- The deliverable consists of two packages: Javascript program and C/Python program. Each needs to include at least 5 example usages and demonstration of interoperability.

## Deliverables

1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.

2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables):

a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment.

3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).

## Platform

Javascript to run in IE 5+, Firefox and Opera 7+.

C/Python code to run in RedHat Linux
