PHP加密，node解密，采用blowfish CBC模式。

blowfish.cbc.js

var crypto = require('crypto');

function BlowFish(){

    this.decode = function(data, password){

        var text = data.split('.');
        var code = text[0];
        var iv = text[1];

        var decipher = crypto.createDecipheriv( 'bf-cbc', new Buffer(password, 'utf8'), new Buffer(iv, 'base64') );
        decipher.setAutoPadding( auto_padding=false );
        return decipher.update( code, 'base64', 'utf8' );
    }
}

var password = 'key';
var data = 'xxxxxxxxxx';

var bf = new BlowFish();
var result = bf.decode(data, password);
console.log(result);

blowfish.cbc.php

<?php

$password = 'key';

$data = 'data:' . mt_rand();

echo $data;
echo '<br>';
//  创建 iv ，无 iv 会提示错误
$size = mcrypt_get_iv_size(MCRYPT_BLOWFISH, MCRYPT_MODE_CBC);
$iv = mcrypt_create_iv($size, MCRYPT_DEV_RANDOM);
//  加密
$enc = mcrypt_encrypt(MCRYPT_BLOWFISH, $password, $data, MCRYPT_MODE_CBC, $iv );

$data = base64_encode($enc) . '.' . base64_encode($iv);


echo $data;
