「當您希望提供身份驗證的客戶端證書未由其中一個CA簽名時，將根本不會顯示」。因爲客戶端知道他們不會被服務器接受，所以不會顯示證書。此外，您的證書可以由中間CA「ICA」進行簽名，並且服務器可以爲您的客戶端顯示根CA「RCA」，即使您的證書由ICA而非RCA簽名，仍然可以讓您選擇證書。 – KyleM 2014-03-18 19:43:32
作爲上述評論的一個例子，考慮一種情況，您有一個根CA（RCA1）和兩個中間CA（ICA1和ICA2）。在Apache Tomcat上，如果您將RCA1導入到信任庫中，則您的Web瀏覽器將顯示所有由ICA1和ICA2簽名的證書，即使它們不在您的信任庫中。這是因爲它不是單個證書而是重要的鏈條。 – KyleM 2014-03-18 19:57:54
「在我看來，這是奇怪的行爲，但我相信這是有原因的」。原因是這就是它在RFC 2246中所說的。沒有什麼奇怪的。允許客戶出示不被服務器接受的證書是奇怪的，而且會浪費時間和空間。 – EJP 2014-07-29 01:42:43
