package cryptotest provides convenience functions for kyber-based APIs.
It is separate from cltest to prevent an import cycle.
NewStream returns a randomStream seeded from seed, for deterministic randomness in tests of random outputs, and for small property-based tests.
This API is deliberately awkward to prevent it from being used outside of tests.
The testing framework runs the tests in a file in series, unless you explicitly request otherwise with testing.T.Parallel(). So one such stream per file is enough, most of the time.
