php - 如何将这个mcrypt php代码转换为nodejs中的相同代码？

Question

我需要转换这个 php 代码:

$cipher_alg = MCRYPT_TRIPLEDES;
$key = "thekey";
$iv = mcrypt_create_iv(mcrypt_get_iv_size($cipher_alg, MCRYPT_MODE_ECB), MCRYPT_RAND);
$encrypted_string = mcrypt_encrypt($cipher_alg, $key, $string, MCRYPT_MODE_ECB, $iv);

return base64_encode($encrypted_string);

到nodejs。

我使用https://github.com/tugrul/node-mcrypt进行了测试但对于相同的字符串，加密结果并不相同:

测试的nodejs代码:

let blowfishCfb = new MCrypt('tripledes', 'ecb');
let iv = blowfishCfb.generateIv();
blowfishCfb.validateKeySize(false);
blowfishCfb.validateIvSize(false);
blowfishCfb.open('thekey', iv);

let ciphertext = blowfishCfb.encrypt(text);

return Buffer.concat([iv, ciphertext]).toString('base64');

你能帮助理解这一点吗？

谢谢

不要将 IV 和密码连接在一起:

let blowfishCfb = new MCrypt('tripledes', 'ecb');
let iv = blowfishCfb.generateIv();
blowfishCfb.validateKeySize(false);
blowfishCfb.validateIvSize(false);
blowfishCfb.open('thekey', iv);

let ciphertext = blowfishCfb.encrypt(text);

return ciphertext.toString('base64');
