Using a .NET .snk Key File for RSA EncryptionDemonstrates how to load and use a .NET .snk key file for RSA encryption. SNK files are created by the Microsoft .NET Strong Name Tool (Sn.exe).
#include <CkRsa.h> void ChilkatSample(void) { CkRsa rsa; bool success; success = rsa.UnlockComponent("Anything for 30-day trial"); if (success != true) { printf("RSA component unlock failed\n"); return; } // Load a public/private key pair from a .snk key file. const char * xmlKey; xmlKey = rsa.SnkToXml("chilkat2.snk"); printf("%s\n",(const char *)xmlKey); // The xmlKey contains both public and private keys. // Import either the public or private for encrypting or // decrypting. rsa.ImportPrivateKey(xmlKey); bool bUsePrivateKey; bUsePrivateKey = true; const char * encryptedText; encryptedText = rsa.EncryptStringENC("Hello World!",bUsePrivateKey); printf("%s\n",(const char *)encryptedText); // Now decrypt with the public key: rsa.ImportPublicKey(xmlKey); bUsePrivateKey = false; const char * decryptedText; decryptedText = rsa.DecryptStringENC(encryptedText,bUsePrivateKey); printf("%s\n",(const char *)decryptedText); // Note: We could have just as well encrypted using the public key // and decrypted using the private key. } |
