(C++) Generate RSA Public/Private Key Pair and Export to PEMC++ example code showing how to generate an RSA public/private key pair and export to PEM files.
#include <CkRsa.h> #include <CkPrivateKey.h> #include <CkPublicKey.h> void ChilkatSample(void) { // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. CkRsa rsa; // Generate a 1024-bit key. Chilkat RSA supports // key sizes ranging from 512 bits to 4096 bits. bool success = rsa.GenerateKey(1024); if (success != true) { std::cout << rsa.lastErrorText() << "\r\n"; return; } // Keys are exported in XML format: const char *publicKeyXml = rsa.exportPublicKey(); std::cout << publicKeyXml << "\r\n"; const char *privateKeyXml = rsa.exportPrivateKey(); std::cout << privateKeyXml << "\r\n"; // Save the private key in PEM format: CkPrivateKey privKey; success = privKey.LoadXml(privateKeyXml); success = privKey.SavePemFile("privateKey.pem"); // Save the public key in PEM format: CkPublicKey pubKey; success = pubKey.LoadFromString(publicKeyXml); success = pubKey.SavePemFile(false,"publicKey.pem"); } |
