File Crypt Pro offers an easy and quick solution to encrypt or decrypt files by dragging the folder into the designated area. The program uses AES-Twofish cascade encryption algorithm for an improved encryption (two ciphers in a cascade operating in XTS mode). Each 128-bit block is first encrypted with Twofish (256-bit key) in XTS mode and then with AES (256-bit key) in XTS mode. Each of the cascaded ciphers uses its own key. All encryption keys are mutually independent.
