Decrypt openssl AES with CryptoJS

Question

I'm trying to decrypt a file encrypted with openssl using CryptoJS 3.1.5.

Everything works fine if I encrypt and decrypt using CryptoJS, same goes for OpenSSL in shell, but when I try to mix CryptoJS with OpenSSL everything goes wrong.

The file is created using this command:

openssl enc -aes-256-cbc -in file.txt -out file.enc -k password

and I try to decrypt like this:

fs.readFile('file.enc', function(err, data) {
  var decrypted = CryptoJS.AES.decrypt(
                    data.toString(),
                    "password",
                    { mode : CryptoJS.mode.CBC }
                  );

  console.log(decrypted.toString(CryptoJS.enc.Utf8));
});

// Give me this err: Uncaught Error: Malformed UTF-8 data

And in the other way, I do :

fs.readFile('file.txt', function(err, data) {
  var encrypted = CryptoJS.AES.encrypt(
                    data.toString(),
                    "password",
                    { mode : CryptoJS.mode.CBC });

  fs.writeFile('file.enc', encrypted);
});

And then in Shell:

openssl enc -d -aes-256-cbc -in file.enc -out file2.txt -k password
// Give me this err: bad magic number

Am I missing something obvious ?

For the record, this is how I decrypt openssl file.

//openssl enc -aes-256-cbc -in file.txt -out file.enc -k password

fs.readFile('file.enc', function(err, data) {
  var salt          = data.toString("hex", 8, 16),
      enc           = data.toString("hex", 16, data.length),
      derivedParams = CryptoJS.kdf.OpenSSL.execute(
                        password,
                        256/32,
                        128/32,
                        CryptoJS.enc.Hex.parse(salt)
                      ),
      cipherParams  = CryptoJS.lib.CipherParams.create({
                       ciphertext : CryptoJS.enc.Hex.parse(enc)
                     }),
      decrypted     = CryptoJS.AES.decrypt(
                        cipherParams,
                        derivedParams.key,
                        { iv : derivedParams.iv }
                      );

  console.log(hex2a(decrypted.toString())); // result is in hexa
});

And this is how I encrypt to make it work with OpenSSL

fs.readFile('file.txt', function(err, data) {
  var encrypted = CryptoJS.AES.encrypt(data.toString(), password);
      buff      = new Buffer(encrypted.toString(), "base64");

  fs.writeFile('file.enc', buff);
});

// openssl enc -d -aes-256-cbc -in file.enc -out file2.txt -k password

Hope it'll help someone :)
