Hash Playground

Hash and verify passwords with Argon2id, scrypt or PBKDF2. The output is a standard PHC string that embeds the algorithm, parameters, and salt — store it as a single column. Hashing runs on the server (Argon2id needs node:crypto), so the demo caps parameters and rate-limits requests.

Hash with a lower cost or another algorithm, then verify: the needsRehash result compares the stored hash to the current Argon2id defaults.
