This file encrypter can use either a string or a file for the code. When using a file, the encryption code can be up to .4GB — virtually unbreakable by any computer. Descriptions can be stored within the encrypted file, as well as the file name of the code. This enables the file to be, for example, e-mailed to another person who has the same collection of codes as you, while not sending the actual code.
