Class KeyPairKey

java.lang.Object
zeroecho.core.alg.common.agreement.KeyPairKey
All Implemented Interfaces:
Serializable, Key
public final class KeyPairKey extends Object implements Key, Serializable
A Key wrapper that carries a KeyPair through APIs that are constrained to Key types.

This type exists to support capabilities that require both private and public components (e.g., message-oriented key agreement contexts), while preserving backward-compatible capabilities that accept only a PrivateKey.

The wrapper does not expose an encoding via getEncoded() because serializing private key material implicitly is dangerous and not required for capability dispatch.

      public byte[] getEncoded()
      Returns null. This wrapper intentionally does not expose a combined encoding.
      Specified by:
      getEncoded in interface Key
      Returns:
      null
