(Unicode C++) Convert Java KeyStore to PEMLoads a Java keystore file and saves the trusted certificate entries to a PEM file. Note: This example requires Chilkat v11.0.0 or greater.
#include <CkJavaKeyStoreW.h> #include <CkFileAccessW.h> #include <CkCertW.h> void ChilkatSample(void) { bool success = false; // This requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. CkJavaKeyStoreW jks; const wchar_t *jksPassword = L"myJksPassword"; // Load the Java keystore from a file. The JKS file password is used // to verify the keyed digest that is found at the very end of the keystore. // It verifies that the keystore has not been modified. success = jks.LoadFile(jksPassword,L"/someDir/keyStore.jks"); if (success == false) { wprintf(L"%s\n",jks.lastErrorText()); return; } // Open/create the output PEM file. // This example uses Chilkat's file access class for writing the output file. // You may replace the file I/O lines of code with whatever is most convenient for you.
