generate-key-pair*clj/s
(generate-key-pair*)(generate-key-pair* private)Generates an internal representation of key pair from a secure random seed or provided private key. Returns map/object with two keys:
- private - a big number/integer
- public - a curve point
If a private key is provided, must be in either hex string or BigInteger (clj) bignumber (cljs).

valid-private?clj/s
(valid-private? private)Returns true if private key, as big number/integer, is valid. Private key must be >= 1 and <= curve modulus.
