Hashing (C)is aone-way cryptographic functionthat produces afixed-length digestrepresenting the original data. If the file changes—even by one bit—the hash will change, making it ideal for verifyingdata integrity.
While encryption protectsconfidentiality, and masking/obfuscation protectdata visibility, onlyhashing ensures integrity.
