Problem with encryption/Decryption code written in Jmeter

I have written a code in beanshell for encryption and decryption in Jmeter but somehow its not working. I am getting error : In file: inline evaluation of: ``import java.security.InvalidAlgorithmParameterException; import java.security.In . . . '' Encountered "}" at line 19, column 82. I have added the crypto jar in test plan but issue persists.

Attached is the code.

Working :

  1. I am generating a random string(R1) and encryption it with a public key using RSA algo.
  2. Using the key R1, I need to encrypt the request body using AES algo, CBC mode, PKCS7Padding.
        package com.sample.feedbackrating;
        import java.security.InvalidAlgorithmParameterException;
        import java.security.InvalidKeyException;
        import java.security.NoSuchAlgorithmException;
        import java.security.SecureRandom;
        import java.util.Base64;
        import java.util.UUID;
        import javax.crypto.BadPaddingException;
        import javax.crypto.Cipher;
        import javax.crypto.IllegalBlockSizeException;
        import javax.crypto.NoSuchPaddingException;
        import javax.crypto.spec.IvParameterSpec;
        import javax.crypto.spec.SecretKeySpec;

    public class Crypto {
    

        public static IvParameterSpec generateIv() {
        byte[] iv = new byte[16];
        return new IvParameterSpec(iv);
    }

        public static String encrypt(String algorithm, String input, String secretKey, IvParameterSpec iv) throws NoSuchPaddingException, NoSuchAlgorithmException, InvalidAlgorithmParameterException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException

    {
    Cipher cipher = Cipher.getInstance(algorithm);
    cipher.init(Cipher.ENCRYPT_MODE, new 
    SecretKeySpec(secretKey.getBytes(), "AES"), iv);
    byte[] cipherText = cipher.doFinal(input.getBytes());
    return Base64.getEncoder().encodeToString(cipherText);
    }
    
    public static String decrypt(String algorithm, String cipherText, String secretKey, IvParameterSpec iv) throws NoSuchPaddingException, NoSuchAlgorithmException,InvalidAlgorithmParameterException, InvalidKeyException,BadPaddingException, IllegalBlockSizeException

    {
    Cipher cipher = Cipher.getInstance(algorithm);
    cipher.init(Cipher.DECRYPT_MODE, new SecretKeySpec(secretKey.getBytes(), "AES"), iv);
    byte[] plainText = cipher.doFinal(Base64.getDecoder().decode(cipherText));
    return new String(plainText);
}

        public static String generateSecretKey() {
            return UUID.randomUUID().toString().replace("-", "");
        }

    }

Encountered "}" is a syntax error so double check your Beanshell script for eventual missing semicolons or closing brackets or whatever. You can use online lint tool like this one to see where exactly the problem is

In general I cannot reproduce your issue:

So it's either a copy-paste issue or a Beanshell-related problem, be aware that starting from JMeter 3.1 you're supposed to use JSR223 Test Elements and Groovy language for scripting, especially for "heavy" tasks like cryptographic operations.
