(C++) Blowfish Encryption to Match PHP's Mcrypt ExtensionDemonstrates how to match Blowfish encryption results with PHP's mcrypt extension. Please refer to this PHP (non-Chilkat) example for PHP Blowfish Encryption. The code here matches the PHP mcrypt results on that web page.
#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; // Use "blowfish2" to get proper results: crypt.put_CryptAlgorithm("blowfish2"); // CipherMode may be "ecb" or "cbc" crypt.put_CipherMode("cbc"); // KeyLength (in bits) may be a number between 32 and 448. // 128-bits is usually sufficient. The KeyLength must be a // multiple of 8. crypt.put_KeyLength(256); // Pad with NULL bytes (PHP pads with NULL bytes) crypt.put_PaddingScheme(3); // EncodingMode specifies the encoding of the output for // encryption, and the input for decryption. // It may be "hex", "url", "base64", or "quoted-printable". crypt.put_EncodingMode("hex"); // The blowfish algorithm uses a 64-bit block size, // therefore the IV must be 8 bytes: const char *ivAscii = "12345678"; crypt.SetEncodedIV(ivAscii,"ascii"); // For 256-bit encryption, the key is 32 bytes: const char *keyAscii = "1234567890123456ABCDEFGHIJKLMNOP"; crypt.SetEncodedKey(keyAscii,"ascii"); const char *plainText = 0; plainText = "The quick brown fox jumped over the lazy dog"; const char *cipherText = crypt.encryptStringENC(plainText); std::cout << cipherText << "\r\n"; // Output should be (case insensitive): // 276855ca6c0d60f7d9708210440c1072e05d078e733b34b4198d609dc2fcc2f0c30926cdef3b6d52baf6e345aa03f83e // Do 128-bit Blowfish encryption: crypt.put_KeyLength(128); keyAscii = "1234567890123456"; crypt.SetEncodedKey(keyAscii,"ascii"); cipherText = crypt.encryptStringENC(plainText); std::cout << cipherText << "\r\n"; // Output should be (case insensitive): // d2b5abb73208aea3790621d028afcc74d8dd65fb9ea8e666444a72523f5ecca60df79a424e2c714fa6efbafcc40bdca } |
