Android App: "Sending and receiving Encrypted SMS"





Uses a substitution algorithm. It can be replaced with any other encryption algorithm: AES, HMAC-SHA1, etc.


It allows the recipient selection which means he or she have got to have the app instaled in order to decrypt the SMS. 
I developed this app while reading the book "The Code Book - The Science of Secrecy from Ancient Egypt to Quantum Cryptography" by Simon Singh just to see whether I was able to and to see whether Singh was not selling me a lot of bullshit...
