OpenPGP Library for .NET

Why should OpenPGP cryptography be complex when it can be as easy as:

PGPLib pgp = new PGPLib();
// should output be ASCII or binary
bool asciiArmor = false;
// encrypt
pgp.EncryptFile(@"C:\INPUT.txt",
                @"C:\recipient_public_key.asc",
                @"C:\OUTPUT.pgp",
                asciiArmor);

Dim pgp As New PGPLib()
' should output be ASCII or binary
Dim asciiArmor As Boolean = False
' encrypt
pgp.EncryptFile("C:\INPUT.txt", _
                "C:\recipient_public_key.asc", _
                "C:\OUTPUT.pgp", _
                asciiArmor)
