(Unicode C++) Verify SSL Server CertificateDemonstrates how to connect to an SSL server and verify its SSL certificate. Note: This example requires Chilkat v11.0.0 or greater.
#include <CkSocketW.h> #include <CkCertW.h> void ChilkatSample(void) { bool success = false; // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. CkSocketW socket; bool ssl = true; int maxWaitMillisec = 20000; // The SSL server hostname may be an IP address, a domain name, // or "localhost". const wchar_t *sslServerHost = 0; sslServerHost = L"www.paypal.com"; int sslServerPort = 443; // Connect to the SSL server: success = socket.Connect(sslServerHost,sslServerPort,ssl,maxWaitMillisec); if (success == false) { wprintf(L"%s\n",socket.lastErrorText()); return; } CkCertW cert; bool bExpired; bool bRevoked; bool bSignatureVerified; bool bTrustedRoot; success = socket.GetServerCert(cert); if (success != false) { wprintf(L"Server Certificate:\n"); wprintf(L"Distinguished Name: %s\n",cert.subjectDN()); wprintf(L"Common Name: %s\n",cert.subjectCN()); wprintf(L"Issuer Distinguished Name: %s\n",cert.issuerDN()); wprintf(L"Issuer Common Name: %s\n",cert.issuerCN()); bExpired = cert.get_Expired(); bRevoked = cert.get_Revoked(); bSignatureVerified = cert.get_SignatureVerified(); bTrustedRoot = cert.get_TrustedRoot(); wprintf(L"Expired: %d\n",bExpired); wprintf(L"Revoked: %d\n",bRevoked); wprintf(L"Signature Verified: %d\n",bSignatureVerified); wprintf(L"Trusted Root: %d\n",bTrustedRoot); } // Close the connection with the server // Wait a max of 20 seconds (20000 millsec) success = socket.Close(20000); } |
