NLS (cipher)

NLS (Nihonba Language System) is a block cipher that was developed as part of a Japanese cryptographic competition. It is designed for the encryption and decryption of data, providing confidentiality through its cryptographic algorithms. NLS uses a combination of substitution and permutation operations to transform plaintext into ciphertext. Typically, block ciphers like NLS operate on fixed-size blocks of data and require a secret key for the encryption and decryption process.
