Notes:
- whether or not the
subjectAltNameextension should be marked Critical depends on the contents of the Certificate’ssubjectfield, as detailed in Section 7.1.2.7.12.- whether or not the CRL Distribution Points extension must be present depends on 1) whether the Certificate includes an Authority Information Access extension with an
id-ad-ocspaccessMethod and 2) the Certificate’s validity period, as detailed in Section 7.1.2.11.2.
注意:
subjectAltName擴充欄位是否應標記為關鍵(Critical),取決於憑證subject欄位之內容,詳見第 7.1.2.7.12 節。- CRL Distribution Points(CRL 發布點)擴充欄位是否應存在,取決於:(1)憑證是否包含 accessMethod 為
id-ad-ocsp之 Authority Information Access(AIA)擴充欄位,以及(2)憑證之有效期,詳見第 7.1.2.11.2 節。
