Class XmssPublicKeySpec

java.lang.Object

zeroecho.core.alg.xmss.XmssPublicKeySpec

All Implemented Interfaces:

AlgorithmKeySpec

public final class XmssPublicKeySpec
extends Object
implements AlgorithmKeySpec

Encoded representation of an XMSS public key in X.509 (SubjectPublicKeyInfo) format.

XMSS public keys are stateless and can be freely shared. The BCPQC provider encodes them as standard X.509 DER, compatible with KeyFactory.generatePublic(java.security.spec.KeySpec).

Since:

1.0
