plugins: expose native crypto library

[alessiodf]

It would be very useful if the native crypto library could be exposed in the plugins sandbox.

One particular use case is that it would allow plugins to generate HMAC access tokens which are required for many external APIs. I think the library is safe enough to not require any permissions and all its functions could be exposed e.g. via walletApi.crypto since none of them appear to be potentially nefarious and all have legitimate use cases within plugins.

Thanks for opening this issue! A maintainer will review this in the next few days and explicitly select labels so you know what's going on.

If no reviewer appears after a week, a reminder will be sent out.

This will need investigating I think. I want to prevent things such as making the OS unresponsive due to intensive hashing which uses up all the machine's resources

This issue or pull request needs further investigation. Please wait for further information, thank you.

while (true) {} would achieve the same effect so I don't think this would do anything that the user couldn't already do if they wanted to lock things up.

Will be addressed in the 3.0 release.
