Hash functions are algorithms that convert variable-length input data into fixed-size bit strings, ensuring data integrity and security. They are essential in cryptography, password storage, and blockchain transactions. With properties like determinism, efficiency, pre-image resistance, and collision resistance, hash functions are vital for protecting digital infrastructures and enabling secure communications.
