How can I decrypt AES-encrypted data in Java and Scala, given that the data was encrypted in Golang with a 128-bit key?

AES Encryption in Golang and Decryption in Java

The Golang code provided encrypts data using the AES algorithm with a 128-bit key. To decrypt this data, we can use a similar Java decoder to ensure compatibility between the two languages.

Java Decoder

<code class="java">String decode(String base64Text, byte[] key) throws InvalidAlgorithmParameterException,NoSuchAlgorithmException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException {
    byte[] inputArr = Base64.getUrlDecoder().decode(base64Text);
    SecretKeySpec skSpec = new SecretKeySpec(key, "AES");
    Cipher cipher = Cipher.getInstance("AES/CFB/NoPadding");
    int blockSize = cipher.getBlockSize();
    IvParameterSpec iv = new IvParameterSpec(Arrays.copyOf(inputArr, blockSize));
    byte[] dataToDecrypt = Arrays.copyOfRange(inputArr, blockSize, inputArr.length);
    cipher.init(Cipher.DECRYPT_MODE, skSpec, iv);
    byte[] result = cipher.doFinal(dataToDecrypt);
    return new String(result, StandardCharsets.UTF_8);
}</code>

Scala Decoder

<code class="scala">def decode(input:String, key:String) = {
    val cipher = Cipher.getInstance("AES/CFB/NoPadding")
    val blockSize = cipher.getBlockSize()
    val keyBytes = key.getBytes()
    val inputArr = Base64.getUrlDecoder().decode(input)
    val skSpec = new SecretKeySpec(keyBytes, "AES")
    val iv = new IvParameterSpec(inputArr.slice(0, blockSize).toArray)
    val dataToDecrypt = inputArr.slice(blockSize, inputArr.size)
    cipher.init(Cipher.DECRYPT_MODE, skSpec, iv)
    new String(cipher.doFinal(dataToDecrypt.toArray))
}</code>

Usage

To decrypt the encrypted text, use the provided Java or Scala decoder. For instance, if the encrypted text is "c1bpFhxn74yzHQs-vgLcW6E5yL8zJfgceEQgYl0=" and the key is "0123456789abcdef", the decrypted text would be "test text 123".
