python aes 加密/解密不返回相同的结果

下面的代码示例在加密/解密操作后没有返回原始文本，我正在尝试找出原因

from Crypto.Cipher import AES

text = """This is plain text
to use.
It should be exqctly 128 characters long to avoid padding and it is split
with new lines as in
file"""

password = "password........"

block = 32
mode = AES.MODE_CBC

enc = AES.new(password, mode)

encrypted = enc.encrypt(text)

print "ORIGINAL: " + text

print "ENCRYPTED: " + str(encrypted)

print "DECRYPTED: " + str(enc.decrypt(encrypted))

谁能告诉为什么文本的第一部分格式不正确？

最佳答案

我认为，您需要重置初始化向量 (IV)，以获得所需的结果。最简单的方法可能是创建一个新的 AES 对象来解密:

enc = AES.new(password, mode)
encrypted = enc.encrypt(text)
print "ORIGINAL: " + text
print "ENCRYPTED: " + str(encrypted)
dec = AES.new(password, mode)
print "DECRYPTED: " + str(dec.decrypt(encrypted))
