// Encryption is where anyone may write a message, but only the private key holder may read it.
// Signing is where anyone may read a message, but only the private key holder may write it.
//
// When you call Decrypt, the RSACryptoServiceProvider is looking for encryption, that is,
// public write private read. Thus it looks for the private key.
// You want to use the SignData and VerifyData functions to sign the payload so that people can't write it.
//

//
// to send a message, call gpg, encrypt with the public key of the recipient,
// and while you're at it sign with the private key of the sender.
// When receiving a message, check the signature against the purported sender's public key,
// and decrypt with the private key of the receiver.
// In other words, send with gpg --sign --encrypt -r NAME_OF_RECIPIENT and receive with gpg --verify followed by gpg --decrypt.
