hashtools.org

Hashtools.org keeps your hashing, checksum, and validation flows in a single interface. Pick a converter, supply input, and copy the signed results in seconds.

No popups, no files stored – just browser-based math for every handshake you need.

HMAC
Hash with confidence

MD5, SHA, and Advanced Hash families (Blake2, SHA3, Keccak, Whirlpool) keep the hashing choices familiar.

Checksum families

Pick CRC16, CRC32, FNV1a, RIPEMD (160/320), or Blake3 and verify results before sharing digests.

Smart randomness

Generate bulk strings, flex length, add a deterministic seed, and refresh until it fits your test plan.

File checker

Upload a file from your browser, choose a checksum, and match it to any hash without storing data.

Email + UUID

Generate domain-friendly addresses, validate input, and grab UUID versions v1–v7 in one place.

GPG ready

Upload a key file, encrypt plaintext, or decrypt ciphertext inside the same control room.

Checksum Studio

CRC, FNV, RIPEMD, and Blake3 keep parity with real-world integration targets.
