Decryption Algorithm needed

$30-100 USD

Paid on delivery
I need a Visual Basic function that will take an encrypted string and return to me the decoded message. The messages are all names, addresses, etc. Now comes the hard part - we have lost the encyrption algorithm that was used to create these. I have hundreds of the encrypted messages with the decrypted results for samples, but we lost the algorithm before we could decipher all of the data. I have a suspicion that the algorithm uses .NET cryptograph library to do the encryption, but am not 100% sure. Let me know if the price is too low on this and I will change the amount. It seems easy, but I know figuring out the encryption may be difficult. The developer has TWO things to complete. First - figure out what algorithm is used to encrypt the messages. Second - complete a VB function that I can pass the rest of the encrypted messages to and have them decoded. ## 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). ## Platform Windows
