AES Crypt is a file encryption software available on several operating systems that uses the industry standard Advanced Encryption Standard (AES) to easily and securely encrypt files. You do not need to be an expert to use AES Crypt, nor do you need to understand cryptography. Using a powerful 256-bit encryption algorithm, AES Crypt can safely secure your most sensitive files. Once a file is encrypted, you do not have to worry about a person reading your sensitive information, as an encrypted file is completely useless without the password. It simply cannot be read. The Mac version of AES Crypt offers a simple to use drag and drop GUI to enable you to securely encrypt and decrypt files on your Mac.
