(C++) Iterate Keys and Certs in PEMDemonstrates how to access each of the private keys and certs contained within a PEM. Note: This example requires Chilkat v11.0.0 or greater.
#include <CkPem.h> #include <CkPrivateKey.h> #include <CkCert.h> void ChilkatSample(void) { bool success = false; // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. CkPem pem; // Load the PEM from a file. // If the PEM is encrypted, provide a password. Otherwise pass an empty string for the password. const char *password = "myPassword"; success = pem.LoadPemFile("../myPemFiles/myPem.pem",password); if (success == false) { std::cout << pem.lastErrorText() << "\r\n"; return; } // Note: If the app already has the PEM pre-loaded in a string variable, then load it // by calling LoadPem instead. const char *pemContent = "... the PEM contents ..."; success = pem.LoadPem(pemContent,password); // Check for success as before.. // Iterate over the private keys. int numPrivateKeys = pem.get_NumPrivateKeys(); int i = 0; CkPrivateKey privKey; while (i < numPrivateKeys) { pem.PrivateKeyAt(i,privKey); std::cout << "Private Key " << i << " is " << privKey.get_BitLength() << " in length" << "\r\n"; i = i + 1; } // Iterate over the certificates. CkCert cert; int numCerts = pem.get_NumCerts(); i = 0; while (i < numCerts) { pem.CertAt(i,cert); std::cout << "Certificate " << i << " : " << cert.subjectDN() << "\r\n"; i = i + 1; } } |
