Twofish Modification

I have a Twofish algorithm Encrypt/Decrypt methods that currently read in the entire file, encrypt/decrypt and then write it back out. The coder will modify the Encrypt/Decrypt methods to use a buffer instead of reading in the whole file. The encrypted file must be base64 encoded as it is in the current method. When decrypting, the file must be base64 decoded as it is in the current method. A test demo form is included in the project. The project will be viewed as complete when the included test image and the test xml file are properly encrypted/decrypted with the newly created buffered Twofish encrypt/decrypt methods. ## 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. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 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). * * *This broadcast message was sent to all bidders on Saturday Oct 6, 2007 9:15:21 PM: Most bidders have asked for the size of the buffer. Just make it a constant of 4096 bytes. ## Platform Visual Studio 2005, C#
