Hashing & Security
Hashes verify that a file arrived intact, sign a webhook, or fingerprint a piece of content. These tools compute digests with the Web Crypto API wherever the browser provides it, and clearly label the algorithms that are no longer collision-resistant. None of them are password hashing functions — for storing passwords you want a deliberately slow algorithm such as Argon2id or bcrypt instead.

HMAC Generator Generate HMAC signatures with a secret key for webhooks and API authentication. MD5 Generator Compute MD5 checksums for legacy file verification — not a security function. SHA-1 Generator Compute SHA-1 digests for legacy compatibility — no longer collision-resistant. SHA-256 Generator Compute SHA-256 digests of text or files using the Web Crypto API.
