All Implemented Interfaces:

Policy

public class DefaultVerificationPolicy
extends PublicationsFileBasedVerificationPolicy

Used to verify extended and not extended signatures with publications file, verification procedure:

• If the signature is already extended, performs publication-based verification and reports the result.
• If the signature is not extended but is old enough to extend, tries to extend it.
• If extending fails for technical reasons, throws technical error.
• If extending fails for cryptographical reasons (extender response inconsistent with signature), reports the result.
• If extending succeeds, performs publication-based verification and reports the result.
• If publication-based verification results in NA, performs key-based verification and reports the result.

Note: Older signature verification may fail if extender is not provided because publications file does not contain old keys for key-based verification.
