Class Summary

Class	Description
CalendarBasedVerificationPolicy	Calendar-based verification takes as input the computed output hash of aggregation hash chains and the `aggregation time'.
ContextAwarePolicyAdapter
DefaultVerificationPolicy	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.
InternalVerificationPolicy	Checks KSI signature's internal consistency.
KeyBasedVerificationPolicy	KSI Signature verification policy.
PolicyContext
