Description:
I need to have an implementation of the TWOFISH encryption algorithm. The program *must* be compilable using gcc or g++ 2.95.3 or 3.0.2 for both unix and win32.

I just need an *example* program that can a) encrypt a file using *twofish* and b) decrypt the same file. It should probably be block cypher and probably CBC (tho i really don't care on which block mode is used).

The use of 3rd-party, open-source libraries is encouraged, though the interface I will use to encrypt/decrypt files must be fairly simple AND usable in a C++ environment.

Again, SIMPLE implementation, either in OOP or otherwise, hopefully just a encrypt(file), decrypt(file).


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

2) SIMPLE implementation, as described above.

3) Complete ownership and distribution copyrights to all work purchased.



Platform:
GNU gcc, g++ for both Win32 and UNIX

Must be 100% finished and received by buyer on:
Sep 25, 2002 11:59:59 PM EDT
Deadline legal notes: All times are expressed in the time zone of the site EDT (UT - 5). If the buyer omitted a time, then the deadline is 11:59:59 PM EDT on the indicated date.

Special Conditions / Other:
Bonus of 10% bid price will be awarded for completion within 24 hours of bid being posted.


Remember that contacting the other party outside of the site (by email, phone, etc.) on all business projects < $500 (before the buyer's money is escrowed) is a violation of both the software buyer and seller agreements. We monitor all site activity for such violations and can instantly expel transgressers on the spot, so we thank you in advance for your cooperation. If you notice a violation please help out the site and report it. Thanks for your help.

Hi Un-Thesis,

I'll create a C++ program which exemplifies Twofish encryption, compatible with Unix and Win32 platforms/compilers. I'll probably be using the OpenSSL open-source crypto library.

I guarantee deliver within the next 24 hours.

Please verify my resume and ratings given by other buyers for references on my past work. I will work closely with you to ensure the final product is exactly what you need.

Contact me to clarify any project details,
Sérgio Silva
