How to verify an Argon2 Hash?

How do you verify an Argon2 Hash with this library in the browser?

Hi! There's no way to do it with the current setup.
If you need verify function, you can add it here: https://github.com/antelle/argon2-browser/blob/master/build-wasm.sh#L8, to EXPORTED_FUNCTIONS list. However I haven't tested it, maybe some fixes will be required.

@antelle - Is there any chance of seeing plain old JavaScript, or WASM support for hash verification in this repo without forking?

Seems like the last missing piece to a perfect, browser-friendly Argon2 implementation.

Added argon2-verify in v1.5.0, here's an example:

argon2.verify({ pass: 'password', encoded: 'enc-hash' })
    .then(() => console.log('OK'))
    .catch(e => console.error(e.message, e.code))

If all my Github issues were resolved as quickly as the ones in this repo I'd be a year ahead of schedule!

Thank you @antelle!
