How to encrypt and decrypt with AES in pycryptodome (Crypto.Cipher.AES): GCM first, CBC when required

Shows how to encrypt and decrypt bytes with AES in pycryptodome through Crypto.Cipher.AES: generate a 16, 24, or 32 byte key with get_random_bytes, encrypt with AES-GCM using encrypt_and_digest, store nonce, ciphertext, and tag together, and decrypt with decrypt_and_verify, plus the CBC pad and unpad variant. Use when…
