我能夠解密運(yùn)行腳本的消息，但當(dāng)我使用用戶輸入法獲取加密消息時(shí)無法解密。我有這個(gè)簡單的腳本：from cryptography.hazmat.primitives.ciphers import Cipher, algorithms, modesfrom cryptography.hazmat.backends import default_backendfrom cryptography.hazmat.primitives import paddingpadder = padding.PKCS7(128).padder()backend = default_backend()def operation_getmessage():    messagesinput = input("Please, insert messages to decrypt: ")    messagesinput = bytes(messagesinput, "utf-8")    message = padder.update(messagesinput)    message += padder.finalize()    return messagekeyinput = input("Please insert the key used for encrypt : ")print(keyinput)key = bytes(str(keyinput), 'ascii')print("key value is :", key)message = operation_getmessage()cipher = Cipher(algorithms.TripleDES(key), modes.ECB(), backend=backend)encryptor = cipher.encryptor()message_encrypt = encryptor.update(message) + encryptor.finalize()print("Value of message_encrypted:", message_encrypt)test = operation_getmessage()print("Value of test: ", test)decryptor = cipher.decryptor()message_decrypt = decryptor.update(test) + decryptor.finalize()print("Value of message_decrypted is: ", message_decrypt)unpadder = padding.PKCS7(128).unpadder()data = unpadder.update(message_decrypt)print("Value of message is: ", data + unpadder.finalize())
