WebbSM4 Encryption is a symmetric key algorithm, which means that the same key is used for both encryption and decryption. It takes a 128-bit plaintext input, breaks it into 32-bit sub-blocks, and processes them in a fixed number of rounds. Each round consists of four operations: substitution, permutation, linear transformation, and key addition.
