While tests in crypto and secp256k1 works, we should verify the mixing of OS entropy in terms of security - is it guaranteed to never weaken what we get from crypto/rand? Also: I would suggest we move the Sha3 helper function to sha3 package (if it's in crypto it creates a circular dependency between crypto and the new randentropy package) |

There was a problem hiding this comment.
I suggest we make this an unexported type and export randentropy.Readerand remove the new(randentropy.RandEntropy) from the other files and pass in the Reader directly.
