## What it is
Node.js bindings to the reference Argon2 password-hashing implementation, supporting Argon2i, Argon2d, and Argon2id. It provides a simple async API for hashing passwords, verifying PHC-formatted hashes, and checking when re-hashing is needed.

## Use cases
- hash user passwords with argon2 in node.js
- verify password against an argon2 hash
- migrate from bcrypt or scrypt to argon2
- check if stored password hashes need re-hashing with new parameters
- generate PHC-formatted argon2 strings

## When to choose
- you need password hashing in a Node.js app with sensible secure defaults
- you want PHC string formatting, verification, and re-hash checks that node:crypto lacks
- you need Argon2i/d/id variants with tunable time, memory, and parallelism costs

## Facets
- artifact type: library
- maturity: stable
- function: cryptography, security, auth
- domain: security, backend, developer-tools
- platform: cross-platform
