Interface XECPrivateKey

All Superinterfaces:
AsymmetricKey, Destroyable, Key, PrivateKey, Serializable, XECKey

public interface XECPrivateKey extends XECKey, PrivateKey
An interface for an elliptic curve private key as defined by RFC 7748. These keys are distinct from the keys represented by ECPrivateKey, and they are intended for use with algorithms based on RFC 7748 such as the XDH 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.
