It looks like you are using an older version of React Native. Please update to the latest release, v0.57 and verify if the issue still exists.

It looks like you did something wrong with your installation of crypto, I don't see how this is a react-native issue.

Please create a repro that shows that the issue is caused by react-native and I'll reopen the issue.
