validity             Validity

            Validity ::= SEQUENCE {
                notBefore      CertificateValidityDate,
                notAfter       CertificateValidityDate }

            CertificateValidityDate ::= CHOICE {
                utcTime        UTCTime,
                generalTime    GeneralizedTime }
