Class SignatureKeyPossessionProofProvider

java.lang.Object

zeroecho.pki.server.confirmation.SignatureKeyPossessionProofProvider

All Implemented Interfaces:

KeyPossessionProofProvider

public final class SignatureKeyPossessionProofProvider
extends Object
implements KeyPossessionProofProvider

Stateless thread-safe provider for the standard ZeroEcho signature key-possession proof suite.

Each call reconstructs the exact immutable suite profile from the supplied portable binding. The provider retains no credential, key, challenge, response, transcript, or mutable verification state and performs no I/O, persistence, clock access, configuration lookup, or lifecycle mutation.
