(JavaScript) Blowfish Encryption to Match PHP's Mcrypt Extension
Demonstrates 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.
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
var crypt = new CkCrypt2();
// Use "blowfish2" to get proper results:
crypt.CryptAlgorithm = "blowfish2";
// CipherMode may be "ecb" or "cbc"
crypt.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.KeyLength = 256;
// Pad with NULL bytes (PHP pads with NULL bytes)
crypt.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.EncodingMode = "hex";
// The blowfish algorithm uses a 64-bit block size,
// therefore the IV must be 8 bytes:
var ivAscii = "12345678";
crypt.SetEncodedIV(ivAscii,"ascii");
// For 256-bit encryption, the key is 32 bytes:
var keyAscii = "1234567890123456ABCDEFGHIJKLMNOP";
crypt.SetEncodedKey(keyAscii,"ascii");
var plainText;
plainText = "The quick brown fox jumped over the lazy dog";
var cipherText = crypt.EncryptStringENC(plainText);
console.log(cipherText);
// Output should be (case insensitive):
// 276855ca6c0d60f7d9708210440c1072e05d078e733b34b4198d609dc2fcc2f0c30926cdef3b6d52baf6e345aa03f83e
// Do 128-bit Blowfish encryption:
crypt.KeyLength = 128;
keyAscii = "1234567890123456";
crypt.SetEncodedKey(keyAscii,"ascii");
cipherText = crypt.EncryptStringENC(plainText);
console.log(cipherText);
// Output should be (case insensitive):
// d2b5abb73208aea3790621d028afcc74d8dd65fb9ea8e666444a72523f5ecca60df79a424e2c714fa6efbafcc40bdca
