(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 <C_CkCrypt2.h> void ChilkatSample(void) { HCkCrypt2 crypt; const char *ivAscii; const char *keyAscii; const char *plainText; const char *cipherText; // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. crypt = CkCrypt2_Create(); // Use "blowfish2" to get proper results: CkCrypt2_putCryptAlgorithm(crypt,"blowfish2"); // CipherMode may be "ecb" or "cbc" CkCrypt2_putCipherMode(crypt,"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. CkCrypt2_putKeyLength(crypt,256); // Pad with NULL bytes (PHP pads with NULL bytes) CkCrypt2_putPaddingScheme(crypt,3); // EncodingMode specifies the encoding of the output for // encryption, and the input for decryption. // It may be "hex", "url", "base64", or "quoted-printable". CkCrypt2_putEncodingMode(crypt,"hex"); // The blowfish algorithm uses a 64-bit block size, // therefore the IV must be 8 bytes: ivAscii = "12345678"; CkCrypt2_SetEncodedIV(crypt,ivAscii,"ascii"); // For 256-bit encryption, the key is 32 bytes: keyAscii = "1234567890123456ABCDEFGHIJKLMNOP"; CkCrypt2_SetEncodedKey(crypt,keyAscii,"ascii"); plainText = "The quick brown fox jumped over the lazy dog"; cipherText = CkCrypt2_encryptStringENC(crypt,plainText); printf("%s\n",cipherText); // Output should be (case insensitive): // 276855ca6c0d60f7d9708210440c1072e05d078e733b34b4198d609dc2fcc2f0c30926cdef3b6d52baf6e345aa03f83e // Do 128-bit Blowfish encryption: CkCrypt2_putKeyLength(crypt,128); keyAscii = "1234567890123456"; CkCrypt2_SetEncodedKey(crypt,keyAscii,"ascii"); cipherText = CkCrypt2_encryptStringENC(crypt,plainText); printf("%s\n",cipherText); // Output should be (case insensitive): // d2b5abb73208aea3790621d028afcc74d8dd65fb9ea8e666444a72523f5ecca60df79a424e2c714fa6efbafcc40bdca CkCrypt2_Dispose(crypt); } |
