-
-Hash an arbitrary string to a point on an elliptic curve.

-## Test case format
-
-The test data is declared in a `data.yaml` file:
-
-```yaml
-input: message: bytes32 -- input message to hash
-output: 
-  x -- x coordinate of the point P output by the hashing,
-  y -- y coordinate of the point P output by the hashing
-```
-
-All byte(s) fields are encoded as strings, hexadecimal encoding, prefixed with `0x`.
