Coded with ❤️ by <a href="#authors">Simone Primarosa</a>.

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:

$scrypt$ln=<cost>,r=<blocksize>,p=<parallelism>$<salt>$<hash>

Where:

Field	Type	Description
`<cost>`	<code>number</code>	The CPU/Memory cost parameter N encoded as log2(N).
`<blocksize>`	<code>number</code>	The block size parameter r.
`<parallelism>`	<code>number</code>	The parallelization parameter p.
`<salt>`	<code>string</code>	A sequence of bits, known as a cryptographic salt encoded in B64.
`<hash>`	<code>string</code>	The computed derived key by the scrypt algorithm encoded in B64.

For more details consult the scrypt paper here.

Install

npm install --save @phc/scrypt

Usage

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

// Hash and verify with scrypt and default configs
const hash = await scrypt.hash('password');
// => $scrypt$ln=15,r=8,p=1$D/EEcdfcBkj4DQB3zlfsFQ$v9Xsag5AySIY78DFKslBzeRXCUfsLKCZ0Xm4Xwoh+J0

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

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

const ids = scrypt.identifiers();
// => ['scrypt']

Benchmarks

Below you can find usage statistics of this hashing algorithm with different options.
This should help you understand how the different options affects the running time and memory usage of the algorithm.

Test vectors

The scrypt paper lists four test vectors to test implementation.
This package implements them here.

API

<dl> <dt><a href="#hash">hash(password, [options])</a> ⇒ <code>Promise.<string></code></dt> <dd>Computes the hash string of the given password in the PHC format using scrypt package. </dd> <dt><a href="#verify">verify(phcstr, password)</a> ⇒ <code>Promise.<boolean></code></dt> <dd>Determines whether or not the hash stored inside the PHC formatted string matches the hash generated for the password provided. </dd> <dt><a href="#identifiers">identifiers()</a> ⇒ <code>Array.<string></code></dt> <dd>Gets the list of all identifiers supported by this hashing function. </dd> </dl>

hash(password, [options]) ⇒ <code>Promise.<string></code>

Computes the hash string of the given password in the PHC format using scrypt package.

Kind: global function
Returns: <code>Promise.<string></code> - The generated secure hash string in the PHC format.
Access: public

Param	Type	Default	Description
password	<code>string</code>		The password to hash.
[options]	<code>Object</code>		Optional configurations related to the hashing function.
[options.blocksize]	<code>number</code>	<code>8</code>	Optional amount of memory to use in kibibytes. Must be an integer within the range (`8` <= `memory` <= `2^32-1`).
[options.cost]	<code>number</code>	<code>15</code>	Optional CPU/memory cost parameter. Must be an integer power of 2 within the range (`2` <= `cost` <= `2^((128 * blocksize) / 8) - 1`).
[options.parallelism]	<code>number</code>	<code>1</code>	Optional degree of parallelism to use. Must be an integer within the range (`1` <= `parallelism` <= `((2^32-1) * 32) / (128 * blocksize)`).

verify(phcstr, password) ⇒ <code>Promise.<boolean></code>

Determines whether or not the hash stored inside the PHC formatted string matches the hash generated for the password provided.

Kind: global function
Returns: <code>Promise.<boolean></code> - A boolean that is true if the hash computed for the password matches.
Access: public

Param	Type	Description
phcstr	<code>string</code>	Secure hash string generated from this package.
password	<code>string</code>	User's password input.

identifiers() ⇒ <code>Array.<string></code>

Gets the list of all identifiers supported by this hashing function.

Kind: global function
Returns: <code>Array.<string></code> - A list of identifiers supported by this hashing function.
Access: public
