There are multiple issues with your code.
crypto.createCipher(algorithm, password) uses a password not a key. The actual key will be derived from that password. It seems that you want to use a key instead of a password, so you need to use crypto.createCipheriv(algorithm, key, iv).
PHP's mcrypt module only applies zero padding, but node.js' crypto module only applies PKCS#5/PKCS#7 padding. You should use PKCS#7 padding in PHP like shown here. (used in the example code)
You have to use the same IV in both node.js and PHP. Usually a random IV is generated and prepended to the ciphertext. During decryption it must be sliced off and used. (not included in the example code)
node.js
var crypto = require('crypto');
var secretKey = new Buffer("efd77bed61e8fdd0437df1ac", "utf8");
var iv = new Buffer("\0\0\0\0\0\0\0\0");
var enchding = 'hex';
var text = 'This is test.';
var cipher = crypto.createCipheriv('des-ede3-cbc', secretKey, iv);
var cryptedPassword = cipher.update(text, 'utf8', enchding) + cipher.final(enchding);
console.log(cryptedPassword);
output:
4e91635045f42185831403057ef16749
PHP
function pkcs7pad($plaintext, $blocksize)
{
$padsize = $blocksize - (strlen($plaintext) % $blocksize);
return $plaintext . str_repeat(chr($padsize), $padsize);
}
$pt = pkcs7pad('This is test.', 8);
$iv = '\0\0\0\0\0\0\0\0';
$key = 'efd77bed61e8fdd0437df1ac';
$ct = mcrypt_encrypt(MCRYPT_3DES, $key, $pt, MCRYPT_MODE_CBC, $iv);
echo bin2hex($ct);
output:
4e91635045f42185831403057ef16749
It seems you want to encrypt passwords. Passwords should never be encrypted. Use a good hashing solution like PBKDF2, bcrypt or scrypt and verify the password by hashing it again.
