KetuFile

KetuFile is an easy-to-use Windows application that allows strong encryption of any type of PC file, including text, word processor, spreadsheet, graphics, binaries, and executables. KetuFile uses the latest US standard for encryption, Advanced Encryption Standard (AES). It allows up to 256 or 512 bit keys respectively for the two available models. Unlike other popular encryption approaches, KetuFile does not have crippling Backdoors or Key Recovery features. Particular attention has been paid to designing KetuFile to allow fast, easy decryption when an encrypted file is received as an email attachment.
