A Sponge function is a type of cryptographic function that operates using a "sponge" construction, which provides a versatile and secure way to construct various cryptographic primitives, such as hash functions, message authentication codes (MACs), and stream ciphers. The key features of sponge functions include the following: 1. **Absorbing Phase**: The input message is absorbed into the state of the sponge by mixing it into the internal state.
