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...
aes-256-gcm 加密 key: 为str,hex字符串,64字符(32字节) aad: 为str,hex字符串,32字符(16字节) ciphertext: 为bytes, 明文 返回: 为bytes, base64 的密文 ''' aes_gcm_ivlen = 12 key_bytes = binascii.unhexlify(key) aad_bytes = binascii.unhexlify(aad) data = ciphertext iv_bytes = os....
AES作为目前最广泛使用的对称加密算法,以其高效的加解密性能和高安全性著称。在Python中,可以通过cryptography库实现AES的加密与解密操作。以下是一个完整的AES-GCM模式加密与解密的流程: from cryptography.hazmat.primitives.ciphers import Cipher, algorithms, modes from cryptography.hazmat.backends import default_backe...
