Class LmsPublicKeySpec

java.lang.Object

zeroecho.core.alg.lms.LmsPublicKeySpec

All Implemented Interfaces:

AlgorithmKeySpec

public final class LmsPublicKeySpec
extends Object
implements AlgorithmKeySpec

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

LMS 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
