Blowfish Encryption to Match PHP's Mcrypt Extension

See more Encryption Examples

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.

Chilkat2 Java

import com.chilkatsoft.chilkat2.Crypt2;

public class ChilkatExample {

    public static void main(String[] args) {
        // This example assumes the Chilkat API to have been previously unlocked.
        // See Global Unlock Sample for sample code.

        Crypt2 crypt = new Crypt2();

        // Use "blowfish2" to get proper results:
        crypt.setCryptAlgorithm("blowfish2");

        // CipherMode may be "ecb" or "cbc"
        crypt.setCipherMode("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.setKeyLength(256);

        // Pad with NULL bytes (PHP pads with NULL bytes)
        crypt.setPaddingScheme(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.setEncodingMode("hex");

        // The blowfish algorithm uses a 64-bit block size,
        // therefore the IV must be 8 bytes:
        String ivAscii = "12345678";
        crypt.setEncodedIV(ivAscii, "ascii");

        // For 256-bit encryption, the key is 32 bytes:
        String keyAscii = "1234567890123456ABCDEFGHIJKLMNOP";
        crypt.setEncodedKey(keyAscii, "ascii");

        String plainText = "The quick brown fox jumped over the lazy dog";

        String cipherText = crypt.encryptStringENC(plainText);
        System.out.println(cipherText);
        // Output should be (case insensitive):
        // 276855ca6c0d60f7d9708210440c1072e05d078e733b34b4198d609dc2fcc2f0c30926cdef3b6d52baf6e345aa03f83e

        // Do 128-bit Blowfish encryption:
        crypt.setKeyLength(128);
        keyAscii = "1234567890123456";
        crypt.setEncodedKey(keyAscii, "ascii");

        cipherText = crypt.encryptStringENC(plainText);
        System.out.println(cipherText);
        // Output should be (case insensitive):
