Hash Functions are a fundamental cryptographic tool for ensuring data integrity. They generate a fixed-length hash value (digest) from input data. Any change in the input, even by a single bit, results in a completely different hash value, making tampering evident. For instance, if a file's hash is computed before transmission and verified upon receipt, any alteration to the file will produce a mismatched hash. Algorithms like SHA-256 are commonly used. Hash functions are widely applied in digital signatures and certificates to validate integrity and detect unauthorized changes. Why Other Options Are Incorrect :
