Verification recomputes the hash, checks the corresponding key and signing time, follows certificate chains to the Controller's self-signed certificate, and checks revocation status, subject to the exception for certificates valid for less than one hour. Long-term validity requires timestamps covering signed data, certificates and revocation information, with nested timestamps extending validity beyond time-stamping key or algorithm expiry. en-us Tue, 25 Aug 2015 00:00:00 +0530 Thu, 01 Oct 2026 13:06:00 +0530 TaxTMI RSS Generator https://www.taxtmi.com/notifications?id=147128 End-entity digital-signature authentication requires private-key creation, public-key verification, hash functions, contextual date and time, and certificate-based trust validation.
