Secure Networking with SSL
summary
Overview of practical SSL with Qt focusing on client side usage, showing code that uses OpenSSL and QNetworkAccessManager/QNetworkReply to fetch HTTPS and inspect certificate chains; demonstrates using QSslSocket and QSslConfiguration for keys, ciphers and CA lists and an example that queries multiple sites and prints issuers (Google, Facebook, Twitter use varying CAs). Covers real failures: Digicert/Comodo/DigiNotar compromises, OCSP vs CRL and OCSP stapling, HSTS and SNI, and notes that browsers trust about 650+ trusted CAs which drives many real-world risks.
