(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.
bool success = false; // This requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.JavaKeyStore jks = new Chilkat.JavaKeyStore(); string jksPassword = "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,"/someDir/keyStore.jks"); if (success == false) { Debug.WriteLine(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. Chilkat.FileAccess fac = new Chilkat.FileAccess(); success = fac.OpenForWrite("/pemFiles/caCerts.pem"); if (success == false) { Debug.WriteLine(fac.LastErrorText); return; } int numCerts = jks.NumTrustedCerts; Chilkat.Cert cert = new Chilkat.Cert(); string pem; // Iterate over the trusted certs, get the PEM for each, // and append it to the output file. int i = 0; while (i < numCerts) { jks.TrustedCertAt(i,cert); // Get the certificate in PEM format. pem = cert.ExportCertPem(); // Append the PEM string to the open file. success = fac.AppendText(pem,"utf-8"); if (success != true) { Debug.WriteLine(fac.LastErrorText); return; } i = i + 1; } // Close the output file. fac.FileClose(); Debug.WriteLine("Trusted certificates saved to PEM."); |
