Hi Mars,

This is a common garbled/corrupted Chinese wording issue, which can be resolved by the use of UTF-8 conversion.

Checking in the plugin itself, the encryption and decryption of wordings in English and numbers are working perfectly fine, while characters in Chinese and Japanese (I have only tested these 2) are going into garbled characters, just as what you are showing in screenshots above. In order to deal with this issue, I looked back into the source code of the plugin, and among all the discussion, I am able to find out this post. Inside the post and comparing it with the function call in the plugin, I am able to find out that the existing way of calling in the plugin has not yet been taking UTF-8 into consideration. And therefore, characters like Chinese or Japanese could result in garbled characters.

Encrypt

Decrypt

In regard of this, I have made changes to the call such that it also now takes UTF-8 into consideration.

Encrypt

var cipher = forge.cipher.createCipher('AES-CBC', $parameters.Key);
cipher.start({iv: $parameters.IV});
cipher.update(forge.util.createBuffer($parameters.Value,'utf8'));
cipher.finish();
$parameters.Encrypted = forge.util.encode64(cipher.output.getBytes());

Decrypt

var decipher = forge.cipher.createDecipher('AES-CBC', $parameters.Key);
decipher.start({iv: $parameters.IV});
decipher.update(forge.util.createBuffer(forge.util.decode64($parameters.Encrypted)));
decipher.finish();
$parameters.Value = decipher.output.toString();

Testing with Chinese, it works. Switched back to English, working as well. Problem solved!

Hope that helps :)

Cheers,

Hillman
