PHP Password Hash Generator / Verifier

Q: Why isn't this tool 100% client-side like your other tools?

password_hash() and PASSWORD_ARGON2ID are PHP-native algorithms with no equivalent in browser JavaScript. To guarantee the output is byte-for-byte what your own PHP backend would produce, this single calculation is sent to our server. It is used only to compute the response and is never logged, stored, or written to a database.

Q: What's the difference between PASSWORD_DEFAULT (bcrypt) and PASSWORD_ARGON2ID?

PASSWORD_DEFAULT currently maps to bcrypt, a well-tested, time-cost algorithm. PASSWORD_ARGON2ID is a newer, memory-hard algorithm that is generally harder to attack with GPUs/ASICs, at the cost of using more RAM per hash.

info An intentional exception to our "never leaves your browser" rule

password_hash() and PASSWORD_ARGON2ID are PHP-native — there is no browser API that reproduces them exactly. To guarantee the hash you get here is byte-for-byte what your own PHP backend would generate, this one calculation is sent to our server, computed by the real PHP engine, and returned. Your input is used only for that single computation — it is never logged, stored, or written to a database.

Algorithm

PASSWORD_DEFAULT (bcrypt) PASSWORD_ARGON2ID

PASSWORD_DEFAULT currently maps to bcrypt in PHP 8.3 and may change to a stronger algorithm in a future PHP version — that's expected, standard PHP behavior.

FAQ

Q: Why isn't this tool 100% client-side like your other tools?

A: password_hash() and PASSWORD_ARGON2ID are PHP-native algorithms with no browser equivalent. This one calculation is sent to our server so the real PHP engine can compute it — the result is guaranteed to match your own PHP backend. Nothing is logged or stored.

Q: What's the difference between PASSWORD_DEFAULT (bcrypt) and PASSWORD_ARGON2ID?

A: PASSWORD_DEFAULT currently maps to bcrypt, a mature, time-cost hashing algorithm. PASSWORD_ARGON2ID is newer and memory-hard, making it more resistant to GPU/ASIC cracking attempts at the cost of higher RAM usage per hash.
