Drag-n-Crypt is an easy to use, drag-n drop encryption program that uses the Twofish algorithm to encrypt and password protect your files. Simple drag the file to be encrypted onto the Drag-n-Crypt drop target and set a password to protect the file. The program will automatically save an encrypted copy of your file with a .dcu extension in the same folder. You can also choose to securely wipe the original file - in which case you will only have the encrypted copy left.
