node-pow-argon2

An Argon2-based proof of work library for Node

Functions

solve

Syntax:

hash = solve (input, options)

Example:

import * as pow from 'node-pow-argon2'
 
...
 
const proof = await pow.solve(input, { complexity: 20 });

Options:

The following options are available, along with their defaults:

{
    timeCost: 1
    memoryCost: 14,   // MUST be at least 3
    parallelism: 2,
    complexity: 8     // MUST be at least 8
}

verify

Syntax:

verify (input, proof, options)

Example:

import * as pow from 'node-pow-argon2'
 
...
const proof = '$argon2d$v=19$m=512,t=3,p=1$x+qyCc4ZcX79+lATSyhEhQ$00056gSabWkJXAlsWK+QRJ3coP5aM8WhtQqP0Ci9VLA';
const input = 'x';
const result = await pow.verify(input, proof, { complexity: 20 });

Options:

The following options are available, along with their defaults:

{
    timeCost: 1       // Proof must have been created with AT LEAST this value to not fail
    memoryCost: 14,   // Proof must have been created with AT LEAST this value to not fail
    parallelism: 2,   // Proof must have been created with EXACTLY this value to not fail
    complexity: 8     // At least 8. Proof MUST have AT LEAST this complexity.
}
