phc-argon2

🔒 Node.JS Argon2 password hashing algorithm following the PHC string format.
_{Coded with ❤️ by Simone Primarosa.}

PHC String Format

The PHC String Format is an attempt to specify a common hash string format that’s a restricted & well defined subset of the Modular Crypt Format. New hashes are strongly encouraged to adhere to the PHC specification, rather than the much looser Modular Crypt Format.

The hash strings generated by this package are in the following format:

$argon2<variant>$v=<version>$m=<memory>,t=<iterations>,p=<parallelism>$<salt>$<hash>

Where:

Field	Type	Description
`<variant>`	`string`	The variant of the algorithm used to derive a key of the input password.
`<version>`	`number`	The version of the argon2 algorithm used.
`<memory>`	`number`	The amount of memory to consume in kibibytes.
`<iterations>`	`number`	The number of iterations desired. The higher the number of iterations, the more secure the derived key will be, but will take a longer amount of time to complete.
`<parallelism>`	`number`	The degree of parallelism to use while computing the hash.
`<salt>`	`string`	A sequence of bits, known as a cryptographic salt encoded in B64.
`<hash>`	`string`	The computed derived key by the argon2 algorithm encoded in B64.

For more details consult the Argon2 paper here.

Install

npm install --save @phc/argon2

Usage

const argon2 = require('@phc/argon2');

// Hash and verify with argon2 and default configs
const hash = await argon2.hash('password');
// => $argon2id$v=19$m=4096,t=3,p=1$PcEZHj1maR/+ZQynyJHWZg$2jEN4xcww7CYp1jakZB1rxbYsZ55XH2HgjYRtdZtubI

const match = await argon2.verify(hash, 'password');
// => true

const match = await argon2.verify(hash, 'wrong');
// => false

const ids = argon2.identifiers();
// => ['argon2d', 'argon2i', 'argon2id']
