nombCrypt

via pdroms

nombCrypt is an encryption program originally made for desktop PC's but then the author decided to port it over for portable devices. It uses a password you provide and encrypts either a block of text or files using 256bit Rijndael (AES). This level of encryption was given the ok to encrypt Top Secret documents. It can of course decrypt as well. This is for Windows Mobile 6. Please enjoy and every developer of course likes to get back feedback.
