Argon2id Password Hasher
Password hashing with presets, bounded custom parameters, PHC output, and verify.
Associated data (the RFC 9106 `ad` input) is not supported: the hash-wasm WASM build exposes no associated-data parameter, and the page never hand-rolls Argon2.
8-64 bytes; 16 is the norm.
m=19456 KiB (19 MiB), t=2, p=1: the first OWASP configuration.
The PHC string ($argon2id$v=19$m=…,t=…,p=…$salt$hash) appears here: algorithm, parameters, salt, and digest in one interoperable format.
