示例

AESGCM.generate_key requires key size in bits rather than bytes, and AESGCM.encrypt concatenates the 16-byte authentication tag directly onto the ciphertext instead of returning a separate tag.

常见的想当然

AESGCM.generate_key takes key length in bytes and AESGCM.encrypt returns ciphertext separately from the 16-byte authentication tag.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• AESGCM.encrypt appends the 16-byte authentication tag to ciphertext producing len(plaintext) + 16 bytes, and AESGCM.generate_key rejects byte lengths with ValueError
• AESGCM.decrypt accepts combined ciphertext and tag and fails with InvalidTag when passed detached ciphertext or mismatched associated data
• AESGCM accepts None for associated_data during encryption and decrypts successfully with b''
