(Unicode 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 <CkPemW.h> #include <CkPrivateKeyW.h> #include <CkCertW.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. CkPemW pem; // Load the PEM from a file. // If the PEM is encrypted, provide a password. Otherwise pass an empty string for the password. const wchar_t *password = L"myPassword"; success = pem.LoadPemFile(L"../myPemFiles/myPem.pem",password); if (success == false) { wprintf(L"%s\n",pem.lastErrorText()); return; } // Note: If the app already has the PEM pre-loaded in a string variable, then load it // by calling LoadPem instead. const wchar_t *pemContent = L"... 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; CkPrivateKeyW privKey; while (i < numPrivateKeys) { pem.PrivateKeyAt(i,privKey); wprintf(L"Private Key %d is %d in length\n",i,privKey.get_BitLength()); i = i + 1; } // Iterate over the certificates. CkCertW cert; int numCerts = pem.get_NumCerts(); i = 0; while (i < numCerts) { pem.CertAt(i,cert); wprintf(L"Certificate %d : %s\n",i,cert.subjectDN()); i = i + 1; } } |
