Bindings to the reference Argon2 implementation.

Usage

It's possible to hash using either Argon2i, Argon2d or Argon2id (default), and verify if a password matches a hash.

To hash a password:

const argon2 = require('argon2');

try {
  const hash = await argon2.hash("password");
} catch (err) {
  //...
}

To see how you can modify the output (hash length, encoding) and parameters (time cost, memory cost and parallelism), read the wiki

To verify a password:

try {
  if (await argon2.verify("<big long hash>", "password")) {
    // password match
  } else {
    // password did not match
  }
} catch (err) {
  // internal failure
}

Migrating from another hash function

See this article on the wiki for steps on how to migrate your existing code to Argon2. It's easy!

TypeScript usage

A TypeScript type declaration file is published with this module. If you are using TypeScript 2.0.0 or later, that means you do not need to install any additional typings in order to get access to the strongly typed interface. Simply use the library as mentioned above.

import * as argon2 from "argon2";

const hash = await argon2.hash(..);

Prebuilt binaries

node-argon2 provides prebuilt binaries from v0.26.0 onwards. They are built every release using GitHub Actions.

The current prebuilt binaries are built and tested with the following systems:

  • Ubuntu 22.04 (x86-64; ARM64 from v0.28.2; ARMv7 from v0.43.0)
  • MacOS 13 (x86-64)
  • MacOS 14 (ARM64 from v0.29.0)
  • Windows Server 2022 (x86-64)
  • Alpine Linux 3.18 (x86-64 from v0.28.1; ARM64 from v0.28.2; ARMv7 from v0.43.0)
  • FreeBSD 14 (x86-64 from v0.29.1; ARM64 from v0.44.0)

Binaries should also work for any version more recent than the ones listed above. For example, the binary for Ubuntu 20.04 also works on Ubuntu 22.04, or any other Linux system that ships a newer version of glibc; the binary for MacOS 11 also works on MacOS 12. If your platform is below the above requirements, you can follow the Before installing section below to manually compile from source. It is also always recommended to build from source to ensure consistency of the compiled module.

Before installing

You can skip this section if the prebuilt binaries work for you.

You MUST have a node-gyp global install before proceeding with the install, along with GCC >= 5 / Clang >= 3.3. On Windows, you must compile under Visual Studio 2015 or newer.

node-argon2 works only and is tested against Node >=18.0.0.

OSX

To install GCC >= 5 on OSX, use homebrew:

$ brew install gcc

Once you've got GCC installed and ready to run, you then need to install node-gyp, you must do this globally:

$ npm install -g node-gyp

Finally, once node-gyp is installed and ready to go, you can install this library, specifying the GCC or Clang binary to use:

$ CXX=g++-12 npm install argon2

NOTE: If your GCC or Clang binary is named something different than g++-12, you'll need to specify that in the command.

FAQ

How do I manually rebuild the binaries? 
$ npx @mapbox/node-pre-gyp rebuild -C ./node_modules/argon2

Run @mapbox/node-pre-gyp instead of node-gyp because node-argon2's binding.gyp file relies on variables from @mapbox/node-pre-gyp.

You can omit npx @mapbox and use just node-pre-gyp if you have a global installation of @mapbox/node-pre-gyp, otherwise prefixing npx will use the local one in ./node_modules/.bin

How do I skip installing prebuilt binaries and manually compile from source?

You can do either of the two methods below:

  1. Force build from source on install.
$ npm install argon2 --build-from-source
  1. Ignore node-argon2 install script and build manually.
$ npm install argon2 --ignore-scripts
$ npx node-gyp rebuild -C ./node_modules/argon2
I installed Node as a snap, and I can't install node-argon2.

This seems to be an issue related to snap (see #345 (comment)). Installing Node with another package manager, such as asdf or nvm, is a possible workaround.
