Designed to be easy to use, Fast Cryptor provides you with the ability to protect your sensitive files from a portable application. The interface is made to be as user-friendly as possible and employs robust encryption algorithms. In minimal clicks, you can encrypt or decrypt a file, ensuring that the personal data contained within is only viewed by the intended recipient.
As with most publicly available encryption tools, nothing is 100% - that said, Fast Encryptor gives you a secure means to protect your sensitive data. Fast Cryptor uses AES 128-bit, 256-bit Towfish 128-bit, 256-bit encryptiondecryption algorithm with EAX/HMAC mode and supports Unicode. You can also shred the source file upon completion of encryption.
Usage is typical of apps in this family; drag 'n drop (or select from a folder or USB) your target in, choose your settings, then hit Start. You will be prompted for a password (Important - remember it, or you'll be out of luck); from there, Fast Cryptor performs the encryption/decryption.
