Encrypt Android and iPhone text messages with TXTcrypt

TXTCrypt is a free app for Android, iPhone, Palm and desktop computer to encrypt any text message, from SMS up to notes, an online version exists to encrypt/decrypt messages if you do not want to download the app.TXTCrypt uses RC4 for encryption, a malleable and quick stream cipher designed in RSA laboratories, these days it is not considered secure enough to withstand a state sponsored attack on your communications but it should stop the average hacker.

TXTCrypt uses symmetric encryption, where you password protect your text message and it can be decrypted by anyone who knows it, a system will have to be designed to pass on the password, which should be as long as possible to employ the full 64bit cipher strength.
