Phrase Password Generator

This tool derives a password by hashing the input phrase with an optional salt and encoding the result into the selected character set. The process is deterministic and runs locally, so the same inputs always yield the same password, with no data sent to servers.
Inputs are phrase, length, salt, and class selections. The algorithm uses SHA-256 to compute a digest from phrase and salt, then maps digest bytes to the allowed alphabet to produce a password of the requested length. If required, the tool enforces at least one character from each selected class using a deterministic post-processing step.
Users include developers and IT security staff who need reproducible credentials without storing secrets. The method supports per-site variation by using a site-specific salt, enabling unique passwords for different accounts while using a single mental phrase.
Value and features include deterministic derivation, per-site salts, length and class customization, and no network dependency. Use cases include initial password creation, password rotation by changing salt, and adapting to site rules that require certain character families. The tool provides a robust, auditable method for offline password generation.
