How do I generate a cryptographically secure random number to use for bearer tokens?

Question

I want to generate a secure random number to use for bearer tokens in vapor swift.

I have looked at OpenCrypto but it doesn't seem to be able to generate random numbers.

How do I do this?

Answer 1

For Vapor you can generate a token like so:

[UInt8].random(count: 32).base64

That will be cryptographically secure to use. You can use it like in this repo
