在Python中,使用AES-GCM模式进行加密时,通常会生成一个认证标签(authentication tag),这个标签可以用来验证数据的完整性。当你解密数据时,如果认证标签不匹配,那么说明数据已经被篡改。 以下是一个使用cryptography库的示例代码,展示了如何验证AES-GCM加密后的数据的完整性: from cryptography.hazmat.primitives.ciphers imp...
AES-GCM是一种高级加密标准(Advanced Encryption Standard)的加密模式,它结合了对称加密算法AES(Advanced Encryption Standard)和GCM(Galois/Counter Mode)模式。在Python中,我们可以使用cryptography库来进行AES-GCM解密。 AES-GCM解密的步骤如下: 导入cryptography库:from cryptography.hazmat.primitives.ciphers.aead import...
GCM (Galois/Counter Mode) 指的是该对称加密采用Counter模式,并带有GMAC消息认证码。随着科学的发展,...
