* Free software with permissive MIT license - no GPL restrictions.
* 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).
* Written in 100% managed C# code.
* Requires .NET 2.0, 3.0, or 3.5 and GPG.EXE or GPG2.EXE executable.
