Jack Grigg 9cb9e0f9bc Generate random test vectors for MapToCurve, GroupHash, Sinsemilla 2021-04-29 12:59:16 +12:00
Jack Grigg c6cd47a5dd Fix Rand.u8() to return unsigned integers 
Existing test vector generators are adjusted to use Rand.i8() so they
generate the same test vectors. We should evaluate these later to
determine whether they should actually use Rand.u8() (and update the
test vectors across the ecosystem).

Jack Grigg 10bdd6c5f8 Split apart MapToCurveSimpleSWU and GroupHash test vectors 
The test vector generators in this repository are meant to output data
that can be copy-pasted or piped to a file. Generating multiple sets of
test vectors from a single file interferes with this.
