How to use "A secure, local entropy source for random number generation" in offchain worker?

Question

The official website tells us there is " A secure, local entropy source for random number generation" . I think it means that I can make use of this feature to generate random number or even generate key pair in offchain worker. I want to know how to implement this.Is there any code snippet that I could learn?

Answer 1

For offchain workers there is the random_seed function. This will return you a random seed that you can use to initialize a random number generator.
