My iPhone Application

Unfortunately discontinued due to lack of interest. I'm leaving the links up for nostalgia purposes for now.

Here is a link to my iPhone application Secure Channel

Secure Channel is a data encryption app that uses AES256 symetric encryption to allow you to encrypt arbitrary text data on iOS devices. More info over at
