在上述代码中,decryptAES函数接受密文、密钥和初始化向量作为输入,并返回解密后的字符串。使用CCCrypt函数进行解密操作,其中CCOperation(kCCDecrypt)表示解密操作,CCAlgorithm(kCCAlgorithmAES)表示AES算法,CCOptions(kCCOptionPKCS7Padding)表示使用PKCS7Padding填充方式。 对于iOS开发中的AES/CBC/PKCS7Padding算法解...
6. AES解密 解密数据时,需要使用相同的AES key和iv,可以使用decrypt方法来解密数据: fromCrypto.Util.Paddingimportunpad# 创建AES解密对象decipher=AES.new(aes_key,AES.MODE_CBC,iv=aes_iv)# 解密数据decrypted_data=decipher.decrypt(encrypted_data)# 去除PKCS7填充unpadded_data=unpad(decrypted_data,16) 1....
