| /** |
| * From RFC 3280: |
| * <p> |
| * The invalidity date is a non-critical CRL entry extension that |
| * provides the date on which it is known or suspected that the private |
| * key was compromised or that the certificate otherwise became invalid. |
| * This date may be earlier than the revocation date in the CRL entry, |
| * which is the date at which the CA processed the revocation. When a |
| * revocation is first posted by a CRL issuer in a CRL, the invalidity |
| * date may precede the date of issue of earlier CRLs, but the |
| * revocation date SHOULD NOT precede the date of issue of earlier CRLs. |
| * Whenever this information is available, CRL issuers are strongly |
| * encouraged to share it with CRL users. |
| * <p> |
| * The GeneralizedTime values included in this field MUST be expressed |
| * in Greenwich Mean Time (Zulu), and MUST be specified and interpreted |
| * as defined in section 4.1.2.5.2. |
| * <pre> |
| * id-ce-invalidityDate OBJECT IDENTIFIER ::= { id-ce 24 } |
| * |
| * invalidityDate ::= GeneralizedTime |
