Multilayer film, optically anisotropic layered body, circularly polarizing plate, organic electroluminescence display device, and manufacturing method

A cipher processing system for allowing file access while maintaining the integrity without a user being aware of the difference between files when the user accesses a file in a folder containing both a ciphertext file and a plaintext file. If a folder stores both a ciphertext file and a plaintext file, the ciphertext file is attached with identification information (preferably, footer information) indicating that the file is a ciphertext file, so that a plaintext file and a ciphertext file can be differentiated from each other when the files are read. A deciphered file gained by removing identification information from a ciphertext file and deciphering the file is delivered to an upper-level application. If the read file is a plaintext file, decipher processing is not executed on the plaintext file but the plaintext file is passed to the upper-level application program.
