1. **Key Length**: AES-256 requires a 256-bit (32-byte) key, but your current key is only 16 bytes long. You need to generate a 32-byte key. 2. **Padding**: Your current implementation uses PKCS7 padding, which is correct, but make sure the…

3. **Padding**: While PKCS7 padding is acceptable, ensure that it is applied correctly. 4. **Cipher Mode**: CBC mode is commonly used, but consider using authenticated encryption modes like GCM (Galois/Counter Mode) for added security. 5.…
