crypto.getRandomValues is not defined

[snikoletopoulos]

On Android I get a crypto.getRandomValues is not defined error.
iOS seems to work fine.

The error started when I upgraded from 2.1.0 to 2.2.0.
With 2.1.0 everything is working fine.

As for the environment and setup
I am on the latest Expo SDK (52)
I have the import "react-native-get-random-values"; before any call to @noble packages
And the polyfills are used

Dependencies versions:
react-native-get-random-values: 1.11.0
@noble/hashes: 1.7.0

I have no android, you will need to debug the issue yourself

[snikoletopoulos]

Can you give me some suggestions as to what might be wrong?

[paulmillr]

I think we have changed the logic lf checking if crypto exists. So, see how it works in 2.1 and diff with 2.2. Maybe it’s related to crypto.subtle

[paulmillr]

see if reverting 57c1d9e helps

[snikoletopoulos]

Can confirm after reverting this commit it works as expected again.
Turns out this error is on iOS as well. My bad.

react-native-get-random-values does not implement crypto.subtle so a polyfill for that is needed.

Alternatively, I see that there are checks in place where crypto.subtle is needed so maybe we can revert the checks in 57c1d9e. That we result in better error messages describing what is actually missing.

I assume you are using noble hashes to get sync methods?
