Overview

A thread safe cryptographically secure random number generator.

This is just a tiny wrapper around crypto/rand which:

• performs buffering - rather than read from /dev/urandom for each random number request, it buffers entropy.
• uses a thread safe pool - rather than locking and one global state, it maintains a buffer of entropy per thread pool.

If you run the included benchmark, you can see this is order of magnitudes faster than just using crypto/rand.

To use it, just create a new random number generator with it:

rng := rand.New(srand.Source)
