I've some encrypted data (list of customers) that are stored in a sql server db. These data are encrypted using visual basic, using a specific dll, from what I could see. The work is develop a program (Visual Basic, . Net or Java) that can Decrypt these data using directly the dll function or emulating its behavior. Sources are needed. For testing purposes I can provide encrypted data and its data deciphered. The funds will be issued only if the developer will be able to prove that his program works and can decrypt the data correctly.
