Using the util.pwHash helper function I run in to some issues when hashing passwords. If the memlimit is set to sensitive it sometimes crashes with this error:

Uncaught (in promise) Error: invalid usage
    at b (libsodium-wrappers.js:1)
    at Object.Te [as crypto_pwhash] (libsodium-wrappers.js:1)
    at util.js:108
    at <anonymous>

This is repeatable in the Chrome test browser I am using for Cypress integration tests but it appears to work fine in Firefox and regular Chrome.

Setting the memlimit to crypto_pwhash_MEMLIMIT_INTERACTIVE as suggested here allows it to work correctly in the chrome test browser. Not sure what the ramifications of this are...

As an aside, the hashing is MUCH faster when the memlimit is set to interactive. It is very slow (~3-4 seconds) using the original configuration.
