TextKrypt

TextKrypt is encryption software, designed especially for sending Plain Text email messages securely through Outlook Express without the fear your email can be read by anyone else other than the intended recipient. TextKrypt uses 256 bit AES/Rijndael for maximum security and peace of mind.

According to NIST, the amount of time needed to crack a 128 bit AES key is estimated to be around 149 trillion years! The amount of time estimated to crack a 256 bit key is so large that it is said to be impossible.
