以下设置，适用于python3.5及以前的

pip  install   pycryptoimport base64from Crypto.Cipher import AESfrom Crypto import RandomBS = 16key = "1234567890123456"pad = lambda s: s + (BS - len(s) % BS) * chr(BS - len(s) % BS)unpad = lambda s : s[:-ord(s[len(s)-1:])]class AESCipher:    def __init__(self, key):        self.key = key    def encrypt(self, raw):        raw = pad(raw)        iv = Random.new().read(AES.block_size)        cipher = AES.new(self.key, AES.MODE_CBC, iv)        return base64.urlsafe_b64encode(iv + cipher.encrypt(raw))    def decrypt(self, enc):        enc = base64.urlsafe_b64decode(enc.encode('utf-8'))        iv = enc[:BS]        cipher = AES.new(self.key, AES.MODE_CBC, iv)        return unpad(cipher.decrypt(enc[BS:]))a = AESCipher(key=key)b = a.encrypt(raw='123456')b1 = b.decode()print(b1,type(b),type(b1))c = a.decrypt(enc='N4wGyzPTnggQtUr_gyGcsxMzU136thzPIc8y3mJ2uxg=')print(c)

python3.6版本的

pip install  cryptographyfrom cryptography.fernet import Fernet##  key = base64.urlsafe_b64encode(os.urandom(32))  生成keydef  encrypt_p(password):        f = Fernet('Ow2Qd11KeZS_ahNOMicpWUr3nu3RjOUYa0_GEuMDlOc=')        p1 = password.encode()        token = f.encrypt(p1)        p2 = token.decode()        return   p2def  decrypt_p(password):        f = Fernet('Ow2Qd11KeZS_ahNOMicpWUr3nu3RjOUYa0_GEuMDlOc=')        p1 = password.encode()        token = f.decrypt(p1)        p2 = token.decode()        return p2
