Açıklamalar

Nesnenin X509Chain , sertifika doğrulaması için kullanılması gereken adlı ChainStatus genel bir hata durumu var. Sertifika doğrulamayı yöneten kurallar karmaşıktır ve ilgili öğelerden birinin veya daha fazlasının hata durumunu yoksayarak doğrulama mantığını fazla basitleştirmek kolaydır. Genel hata durumu, zincirdeki her öğenin durumunu dikkate alır.
