EdECPrivateKey

interface EdECPrivateKey : EdECKey, PrivateKey
java.security.interfaces.EdECPrivateKey

An interface for an elliptic curve private key as defined by RFC 8032: Edwards-Curve Digital Signature Algorithm (EdDSA). These keys are distinct from the keys represented by ECPrivateKey, and they are intended for use with algorithms based on RFC 8032 such as the EdDSA Signature algorithm.

An Edwards-Curve private key is a bit string. This interface only supports bit string lengths that are a multiple of 8, and the key is represented using a byte array.

Added in API level 33
abstract fun getBytes(): Optional<ByteArray!>!

Get a copy of the byte array representing the private key. This method may return an empty Optional if the implementation is not willing to produce the private key value.

Return
Optional<ByteArray!>! an Optional containing the private key byte array. If the key is not available, then an empty Optional.
