Argon2 WebAssembly

Argon2 (with Argon2u support) run as WebAssembly.

Usage

``
> let argon2 = require('.');
> argon2.hash({pass: 'password', salt: 'somesalt', distPath: 'dist'}).then(console.log);
{ hash:
Uint8Array [ ... ],
hashHex:
'f38afe1266d247cf1f6f836ffdbb0ab946c0a7edbcb4ba6e7324b32b9050441e',
encoded:
'$argon2d$v=19$m=1024,t=10,p=1$c29tZXNhbHQ$84r+EmbSR88fb4Nv/bsKuUbAp+28tLpucySzK5BQRB4' }
`

The input object has the following parameters and defaults:

`
{string} pass password string
{string} salt salt string
{float} time (1) the number of iterations
{float} mem (1024) used memory, in KiB
{float} hashLen (24) desired hash length
{float} parallelism (1) desired parallelism (will be computed in parallel only for PNaCl)
{number} type (argon2.types.Argon2d) hash type: argon2.ArgonType.Argon2d, .Argon2i, .Argon2id or .Argon2u
{string} distPath ('.') asm.js script location, without trailing slash
`

Building

Prerequisites:

- emscripten with WebAssembly support (howto)
- CMake

Use the provided build script:

`bash
./build.sh
`

You can also use npm run-script build`, which will call that directly.
