(C++) PBES1 Password-Based Encryption (PBE)Demonstrates how to implement password-based encryption according to the PKCS #5 v2.0: Password-Based Cryptography Standard (published by RSA Laboratories). This example uses PBES1, which ise based on the PBKDF1 function and an underlying block cipher such as RC2, DES, etc.
#include <CkCrypt2.h> void ChilkatSample(void) { // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. CkCrypt2 crypt; // Set properties for PBES1 encryption: crypt.put_CryptAlgorithm("pbes1"); crypt.put_PbesPassword("mySecretPassword"); // Set the underlying PBE algorithm (and key length): // For PBES1, the underlying algorithm must be either // 56-bit DES or 64-bit RC2 // (this is according to the PKCS#5 specifications at // http://www.rsa.com/rsalabs/node.asp?id=2127 ) crypt.put_PbesAlgorithm("rc2"); crypt.put_KeyLength(64); // The salt for PBKDF1 is always 8 bytes: crypt.SetEncodedSalt("0102030405060708","hex"); // A higher iteration count makes the algorithm more // computationally expensive and therefore exhaustive // searches (for breaking the encryption) is more difficult: crypt.put_IterationCount(1024); // A hash algorithm needs to be set for PBES1: crypt.put_HashAlgorithm("sha1"); // Indicate that the encrypted bytes should be returned // as a hex string: crypt.put_EncodingMode("hex"); const char *plainText = "To be encrypted."; const char *encryptedText = crypt.encryptStringENC(plainText); std::cout << encryptedText << "\r\n"; // Now decrypt: const char *decryptedText = crypt.decryptStringENC(encryptedText); std::cout << decryptedText << "\r\n"; } |
