indutny / brorand Goto Github PK

Hello @indutny

Hope you well. I was working on elliptic on Cordova-like platform (ios & android) and got an error here https://github.com/indutny/brorand/blob/master/index.js#L21 L22

rand.getByte() & rand.getBytes() are not supported

We know why but i wonder if you are aware to introduce other plateform in brorand such-as expo-random or maybe a native implementation for mobile plateform ?

This is a only blocking point to use elliptic on mobile plateform.

All the best
Michael

This is just mind blown. I can't find any blog post or discussion about this module, despite that, it still has more than 2 million downloads on npm.

does the code in the catch (with the cryptic reference to randy) actually do anything?

I'm trying to use elliptic.js in WebWorker. And I've got this error.

TypeError: Не удалось получить свойство "getByte" ссылки, значение которой не определено или является NULL

I fixed this problem by

• changing window to self https://github.com/indutny/brorand/blob/master/index.js#L19, cause some browsers allows to use crypto from WebWorker
• addingpseudoRandomBytes function if crypto.getRandomValues is not allowed

Commit #7 breaks the use of brorand by bcoin in Cordova.

You never define self anywhere, and it throws TypeError: Cannot read property 'getRandomValues' of undefined. I don't know how this is supposed to work...
