SharpPrivacy is an OpenPGP implementation in C#. It can be used to encrypt and sign data, created OpenPGP compatible keys, and a lot more. This article explains how to use the library in your own .NET application or webpage to encrypt, sign, decrypt or verify OpenPGP messages.

My name is Daniel and I am from Austria.
When I was in High School, all I wanted to do was programming. After finishing High School, I joined a company for which I wrote a project management utility in Visual Basic 6. It was then that I realised that programming all day long was nothing I wanted to do for the rest of my life.

I quit the job and started to study computer and media security at polytechnical university in Hagenberg/Austria.

As of now, I'm still studying. I still like to program, as long as I can do something else too. Recently I switched my favorite programming language to c#. Together with a friend from university, we started a project where we implement OpenPGP (RFC2440) in c#.
