The Encrypt attribute is the whole point of this project. By just decorating a property with this attribute, your datacontext will transparently encrypt and decrypt that value upon serialization to Azure Table storage. Each property is encrypted by a symmetric key for fast access....
Why use a symmetric key?Encryption/decryption performance of the
symmetric key is much faster than using a x509 certificate. Click on the link for
symmetric key to learn more about that implementation.
