/**
 * An interface for an elliptic curve private key as defined by RFC 7748.
 * These keys are distinct from the keys represented by {@code ECPrivateKey},
 * and they are intended for use with algorithms based on RFC 7748 such as the
 * XDH {@code KeyAgreement} algorithm.
 *
 * An XEC private key is an encoded scalar value as described in RFC 7748.
 * The decoding procedure defined in this RFC includes an operation that forces
 * certain bits of the key to either 1 or 0. This operation is known as
 * "pruning" or "clamping" the private key. Arrays returned by this interface
 * are unpruned, and implementations will need to prune the array before
 * using it in any numerical operations.
