OpenPGP Component

OpenPGP Component is a handy .NET 2.0 C# component library specially designed for PGP encrypting, decryption, and signing data using any System.IO.Stream object.
The component interfaces with open source GnuPG and can retrieve key ring data as a DataTable. It also supports async calls.
Multiple VB.NET and C# examples.
Interfaces directly with the GnuPG GPG.EXE command line tool to sign, encrypt and decrypt data using .NET Streams.
Locates the GPG.EXE executable two different ways - the Windows registery or by user supplied path.
Retrieve a collection or DataSet of the keys loaded in the local key ring.
Use as a DLL or add the source code directly to your project.
Encrypt and decrypt examples given in C# and VB.NET.
Asynchronous encryption and decryption examples given in C# and VB.NET.
Integrated Visual Studio.NET help documentation.
Accepts any System.IO.Stream object from reading and writing encryption data.
Output type either as ASCII Armor or Binary
Supports optional passphrases when decryption data.
Both Encrypt and Decrypt methods have corresponding EncryptAsync and DecryptAsync methods to support background processing.
Supports the new Microsoft Asynchronous Model so you can just fire and forget asynchronous calls (no Begin/End needed).
