(Unicode 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_CkCrypt2W.h> void ChilkatSample(void) { HCkCrypt2W crypt; const wchar_t *ivAscii; const wchar_t *keyAscii; const wchar_t *plainText; const wchar_t *cipherText; // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. crypt = CkCrypt2W_Create(); // Use "blowfish2" to get proper results: CkCrypt2W_putCryptAlgorithm(crypt,L"blowfish2"); // CipherMode may be "ecb" or "cbc" CkCrypt2W_putCipherMode(crypt,L"cbc"); // KeyLength (in bits) may be a number between 32 and 448. // 128-bits is usually sufficient.
