एसएसएल पर प्रमाणीकरण के लिए वेब सेवाएँ टीएलएस 1.2 के कारण विंडोज सर्वर 2012 और आईआईएस 8 पर विफल रहीं


1

SSLv3 प्रोटोकॉल में Google टीम द्वारा खोजे गए POODLE नामक एक SSL भेद्यता है। इसलिए SSLv3 का उपयोग करने के लिए सुरक्षित नहीं है। अब इसकी टीएलएस 1.2 का उपयोग करने की सिफारिश की गई है। हमारे पास आईओएस एप्लिकेशन हैं जो लॉग इन ऐप के लिए एसएसएल पर वेब सेवाओं का उपयोग कर रहे हैं। ऐप्स ने iOS 10 के रूप में एरर फेंकना शुरू कर दिया है, उन्होंने TLS 1.2 को अनिवार्य कर दिया है, जिसके कारण हमें त्रुटि हो रही है।

मैंने टीएलएस 1.2 को अपडेट करने के लिए स्क्रिप्ट का अनुसरण करने की कोशिश की है, लेकिन अभी भी लॉगिन समस्या है।
