TROAESEncryptionEnvelope

Overview

The TROAESEncryptionEnvelope provides a simple Message Envelope that can be used to encrypt on-the-wire communication using the widely-known symetric AES/Rijndael encryption algorithm.

To use the TROAESEncryptionEnvelope, simply drop it on your form (or instantiate it in code) and hook it up with the message's Envelopes collection property.
