I don’t have enough information to provide a specific answer for your question. It seems like you are trying to debug JavaScript code that uses JSX syntax.

The provided code snippet appears to be a part of a larger application and might not run as is due to missing imports, dependencies, or other context. The error message about an unexpected token `<` suggests a syntax issue.

Could you please provide more information or clarify what your question is? What are you trying to achieve with this code? Are there any specific errors or issues you're facing?

If you provide the full code snippet or more context, I'll be happy to help.

Given the additional context, it appears that the provided code snippet is a Java implementation of an AES encryption algorithm using the javax.crypto package. The code defines various constants and variables for the encryption process.

To refine the original answer based on this new context:

*   The original question about the Python code snippet doesn't apply here since the provided code is in Java.
*   However, if we're looking to implement a similar AES encryption algorithm in Python using the cryptography library, the approach would be different. In that case, you could use the Fernet symmetric encryption algorithm from the cryptography library for AES-like functionality.

Here's an example of how to encrypt and decrypt strings using AES with a 256-bit key:

```python
from cryptography.hazmat.primitives import padding
from cryptography.hazmat.primitives.ciphers import Cipher, algorithms, modes
from cryptography.hazmat.backends import default_backend
import os

def aes_encrypt(plain_text, key):
    # Generate a random initialization vector (IV)
    iv = os.urandom(16)

    # Create an AES-CBC cipher object with the given key and IV
    cipher = Cipher(algorithms.AES(key), modes.CBC(iv), backend=default_backend())
    encryptor = cipher.encryptor()

    # Pad the plaintext to a multiple of the block size (16 bytes for AES-128)
    padder = padding.PKCS7(128).padder()
    padded_data = padder.update(plain_text) + padder.finalize()

    # Encrypt the padded data
    encrypted_data = encryptor.update(padded_data) + encryptor.finalize()

    return iv + encrypted_data

def aes_decrypt(cipher_text, key):
    # Extract the IV from the cipher text
    iv = cipher_text[:16]
    encrypted_data = cipher_text[16:]

    # Create an AES-CBC cipher object with the given key and IV
    cipher = Cipher(algorithms.AES(key), modes.CBC(iv), backend=default_backend())
    decryptor = cipher.decryptor()

    # Decrypt the encrypted data
    decrypted_padded_data = decryptor.update(encrypted_data) + decryptor.finalize()

    # Unpad the decrypted padded data
    unpadder = padding.PKCS7(128).unpadder()
    plain_text = unpadder.update(decrypted_padded_data) + unpadder.finalize()

    return plain_text

# Usage example:
key = os.urandom(32)
plain_text = b"Hello, World!"
cipher_text = aes_encrypt(plain_text, key)

print(f"Cipher text: {cipher_text.hex()}")

decrypted_plain_text = aes_decrypt(cipher_text, key)
print(f"Decrypted plain text: {decrypted_plain_text.decode()}")
```

This example demonstrates how to encrypt and decrypt strings using AES-256-CBC with a randomly generated key in Python.
