Trouble using verify

[mymindstorm]

Hi,

I've been using the example webpack code, and I'm having some trouble getting verify to work.

Broken code

```js const argon2 = require('argon2-browser'); argon2 .hash({ pass: 'p@ssw0rd', salt: 'somesalt' }) .then(hash => { console.log(hash); argon2 .verify({ pass: 'p@ssw0rd', encoded: hash.encoded }) .then(() => console.log('Hash correct')) .catch(e => console.log(e)); }); ```

The above code generates a hash correctly, but it never fulfills or rejects the argon2.verify promise.

Working code

```js argon2 .verify({ pass: 'p@ssw0rd', encoded: '$argon2d$v=19$m=1024,t=1,p=1$c29tZXNhbHQ$JGOjI98eRw4ahgg28250Fz2BKEFl48Xm' }) .then(() => console.log('Hash correct')) .catch(e => console.log(e)); ```

I then manually copied the string into another promise, which works fine and reaches 'Hash correct'.

---

Additionally, I found that if you try to do more than one thing at once, it will have problems allocating memory.

More bad code

```js const argon2 = require('argon2-browser'); argon2 .hash({ pass: 'p@ssw0rd', salt: 'somesalt' }) .then(hash => { console.log(hash); }); argon2 .hash({ pass: 'p@ssw0rd', salt: 'somesalt' }) .then(hash => { console.log(hash); }); ```

This will fail with

argon2.js:77 Uncaught (in promise) TypeError: Module.allocate is not a function
    at allocateArray (argon2.js:77)
    at eval (argon2.js:106)

Not sure if I'm just doing something wrong. I'm hoping that you could point me in the right direction.

Thanks for reporting this! That's what the bug report should look like. 🎁 There are actually two issues here:

1. subsequent initialization always threw an error, fixed in cab936d8aae21103a13af98f78e76d8e7cf24997
2. strings were allocated without a null terminator, fixed in 31bbf70336870852e4fe5be74c0b64aeb9b6b709

Published v1.7.0, updated the usage example, now your code works in webpack and node.js versions.

Thanks for the quick fix!

cab936d confirmed fixed.

31bbf70 does not fix, still getting e.allocate is not a function with the second bad code sample.

Fixed that one too (it passed in node, but not in browser).
