Help needed with Groovy !

[das_sappo]

Hi Experts,

I am using following Groovy script in Integration Suite to encrypt the payload but getting numeric output in bytes.

Could you please advise or review the code ?

def Message processData(Message message) {
       
  def body = message.getBody(String);
  String ALGORITHM = "AES/CBC/PKCS5Padding";
  String key ="86dh577a8h0a402eed195f7f1798850d";

Cipher cipher = Cipher.getInstance(ALGORITHM);
byte[] messageArr = body.getBytes();
byte[] keyparam=key.getBytes();
SecretKeySpec keySpec = new SecretKeySpec(keyparam, "AES");
byte[] ivParams = new byte[16];
byte[] encoded = new byte[messageArr.length + 16];
System.arraycopy(ivParams,0,encoded,0,16);
System.arraycopy(messageArr, 0, encoded, 16, messageArr.length);
cipher.init(Cipher.ENCRYPT_MODE, keySpec, new IvParameterSpec(ivParams));
byte[] encryptedBytes = cipher.doFinal(encoded);
encryptedB = Base64.getEncoder().encode(encryptedBytes);
def encryptString = encryptedB.toString();
message.setBody(encryptString);
 return message;

Dear Arvik,

If you want the output as a Base64 encoded string then I would say use "encodeToString" method rather than "encode" method.

import com.sap.gateway.ip.core.customdev.util.Message

import javax.crypto.Cipher
import javax.crypto.spec.IvParameterSpec
import javax.crypto.spec.SecretKeySpec;



def Message processData(Message message) {
        def body = message.getBody(String);
        String ALGORITHM = "AES/CBC/PKCS5Padding";
        String key ="86dh577a8h0a402eed195f7f1798850d";

        Cipher cipher = Cipher.getInstance(ALGORITHM);
        byte[] messageArr = body.getBytes();
        byte[] keyparam=key.getBytes();
        SecretKeySpec keySpec = new SecretKeySpec(keyparam, "AES");
        byte[] ivParams = new byte[16];
        byte[] encoded = new byte[messageArr.length + 16];
        System.arraycopy(ivParams,0,encoded,0,16);
        System.arraycopy(messageArr, 0, encoded, 16, messageArr.length);
        cipher.init(Cipher.ENCRYPT_MODE, keySpec, new IvParameterSpec(ivParams));
        byte[] encryptedBytes = cipher.doFinal(encoded);
        encryptedB = Base64.getEncoder().encodeToString(encryptedBytes);
        //def encryptString = encryptedB.toString();
        message.setBody(encryptedB);
        return message;
    }

Thanks,

Asutosh
