WebJun 22, 2024 · Cryptographic hash functions have a lot of information-security applications, notably in: Digital signatures Message authentication codes Ordinary hash functions Indexing data in hash functions Fingerprinting Detecting duplicate data or uniquely identify files Checksums Verifying the integrity of messages and files Password verification WebNote: In Qt versions before 5.9, when asked to generate a SHA3 hash sum, QCryptographicHash actually calculated Keccak. If you need compatibility with SHA-3 hashes produced by those versions of Qt, use the Keccak_ enumerators. Alternatively, if source compatibility is required, define the macro QT_SHA3_KECCAK_COMPAT.
