Core library for MasterPassX, implementation of original MasterPassword algorithm.
createKey(name, master[, options]) creates an base key for a user from name & master password.
Options is {interruptStep}. See scrypt-async-modern. Recommended to not supply this value, unless you are having issues with your runtime crashing. Then I suggest use of 4096.
createSeed(key, site, counter) creates a base seed for a site with a user key (from createKey), a site (usually domain), and a counter (start at 1).
createPassword(seed, template) creates a password from a site seed (from createSeed) and template (from: maximum, long (default), medium, basic, short, pin, name, phrase).
createNamespace(namespace) creates a full namespace and returns an object with {createKey, createSeed, createPassword} using the custom namespace.
See test.
yarn test or npm test
For the base key derivation, we use scrypt-async. This is a fully JavaScript scrypt implentation, which works in browser (and is quick, takes ~0.5 seconds on average).
Next we use crypto-js for a JavaScript HMAC-SHA256. Very quick. Could be used alongside WebCrypto when more support is available.
We also use buffer to mimic the Node.js Buffer in the browser.
The goal was to have a set of library and code that works both on browsers and Node.js, and is very quick.
