"Airscanner Mobile Encrypter secures data residing on your personal data assistant (PDA) and lets you lock your device to keep others from using it. Airscanner Mobile Encrypter has user-selectable, popular encryption and decryption algorithms such as 40-bit RC2, 40-bit RC4 and 56-bit DES and also offers Microsoft's Enhanced CryptoAPI, which supports strong, 128-bit RC4 encryption/decryption algorithms.
