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.
MD5, SHA, and Advanced Hash families (Blake2, SHA3, Keccak, Whirlpool) keep the hashing choices familiar.
Pick CRC16, CRC32, FNV1a, RIPEMD (160/320), or Blake3 and verify results before sharing digests.
Generate bulk strings, flex length, add a deterministic seed, and refresh until it fits your test plan.
Upload a file from your browser, choose a checksum, and match it to any hash without storing data.
Generate domain-friendly addresses, validate input, and grab UUID versions v1–v7 in one place.
Upload a key file, encrypt plaintext, or decrypt ciphertext inside the same control room.
CRC, FNV, RIPEMD, and Blake3 keep parity with real-world integration targets.
Drop in secrets and verify tags in batch without leaving the browser.
Upload files safely or get the file's checksum in a single passthrough.
Bring your key, encrypt, or decrypt data securely inside the lab.
