備註

這個類別類似于 或 IssuerName 屬性的延伸 SubjectName ,這是要核發憑證之人員或實體的名稱。 X.500 是分散式目錄服務的國際標準。 辨別名稱使用下列格式:

[X500:/C=CountryCode/O=Organization/OU=OrganizationUnit/CN=CommonName]

適用下列欄位長度限制:

欄位 長度限制
CountryCode 2 個字元
組織 最多 64 個字元
OrganizationUnit 最多 32 個字元
CommonName 最多 64 個字元

以下是適用的方針:

  • 域值可以是大寫或小寫。

  • 分隔符號是斜線標記 (/) ,且必須在第一個值之前和後續值之間出現。

  • 分隔符號後面可以接著空格。

以下是正確格式化名稱的範例:[X500:/C=US/ O=Microsoft/ OU=WGA/ CN=TedSt]
