It's not a few hours, but 2 or 3 days and you should easily get it done (at least, I'd consider investigating it).
Maybe for you, but I am not so sure about it myself. I think that I would rather try out my existing options first to see how they try out. system.security.cryptography already supports rijndale and sha-1. I am aware that sha-1 has issues but this is a legacy application so I am kind of stuck with it. Bouncy Castle (http://www.bouncycastle.org/csharp/) has support for Elliptic Curve but I am not sure how close that would be to what the Delphi developer actually wrote. While there are standards in implementing these algorithms, not everyone implements them in an identical fashion, especially if that developer did so years ago and is no longer available to ask.
