SDK ID Encryption Configuration

To use the larksr SDK, you first need to obtain an SDK authorization code from Pingxingyun Business (business@pingxingyun.com) or at https://www.pingxingyun.com/console (note that this is not the server-side authorization code).

Pass the authCode through larksr config or set the authorization code using the method larksr.initSDKAuthCode('YourSDKID').

To protect the security of the SDK ID, from server version 3.2.3.0 onwards, you can configure SDK ID encryption.

Configure SDK encryption:

1. First, log in to the larkxr platform backend, find System Settings -> Access Management -> SDKID Key Management to generate an SDK ID encryption key.

2. Encrypt the SDK ID

The following is an example in Java:

public static void main(String[] args) {
    /**
    * @param res   The original string to be encrypted
    * @param key   16-character key for encryption
    */
    try {
        String res = "The original string to be encrypted";
        String key = "16-character key for encryption";
        String ALGORITHM = "AES";
        String CHARSET = "UTF-8";
        SecretKeySpec sks = new SecretKeySpec(key.getBytes(CHARSET), ALGORITHM);
        Cipher cipher = Cipher.getInstance(ALGORITHM);
        cipher.init(cipher.ENCRYPT_MODE, sks);
        byte[] result = cipher.doFinal(res.getBytes());
        // BASE64Encoder encoder = new BASE64Encoder();      //java8
        Base64.Encoder encoder = Base64.getEncoder(); //java9+
        System.out.println(encoder.encodeToString(result));
    } catch (Exception e) {
    }
}

1. Pass the encrypted string into the lark configuration.
