* A secret key is valid if it is not 0 and less than the secp256k1 curve order
* when interpreted as an integer (most significant byte first). The
* probability of choosing a 32-byte string uniformly at random which is an
* invalid secret key is negligible.
* invalid secret key is negligible. However, if it does happen it should
* be assumed that the randomness source is severely broken and there should
* be no retry.

* Returns: 1: secret key is valid
* 0: secret key is invalid
