func MaybeReadByte ¶

func MaybeReadByte(r io.Reader)

MaybeReadByte reads a single byte from r with ~50% probability. This is used to ensure that callers do not depend on non-guaranteed behaviour, e.g. assuming that rsa.GenerateKey is deterministic w.r.t. a given random stream.

This does not affect tests that pass a stream of fixed bytes as the random source (e.g. a zeroReader).
