HC-256 is a cryptographic stream cipher designed by Hongjun Wu. It belongs to the family of cryptographic algorithms known as stream ciphers, which encrypt data one bit or byte at a time, making it suitable for applications where data needs to be encrypted in real-time or continuously. ### Key Features of HC-256: 1. **Key Size**: HC-256 typically supports a key size of 256 bits, although variations may exist.
