Python实现AES加解密和MD5加密方法

通过Python实现AES加解密和MD5加密方法

def add_to_16(self,text):
    #进行长度补足
    while len(text) % 16 != 0:
        text += '\0'
    return text

def encrypt(self,data, password):
    """
    AES加密
    :param data:需要加密的数据
    :param password: 私钥
    :return:
    """
    if isinstance(password, str):
        password = password.encode('utf8')

    bs = AES.block_size
    pad = lambda s: s + (bs - len(s) % bs) * chr(bs - len(s) % bs)
    cipher = AES.new(password, AES.MODE_ECB)
    data = cipher.encrypt(pad(data).encode('utf8'))
    encrypt_data = binascii.b2a_hex(data)  # 输出hex
    # encrypt_data = base64.b64encode(data)         # 取消注释,输出Base64格式
    return encrypt_data.decode('utf8')

def decrypt(self,decrData, password):
    """
    AES解密
    :param decrData: 加密后的数据
    :param password: 私钥
    :return:
    """

    if isinstance(password, str):
        password = password.encode('utf8')

    cipher = AES.new(password, AES.MODE_ECB)
    plain_text = cipher.decrypt(binascii.a2b_hex(decrData))
    return plain_text.decode('utf8').rstrip('\0')

def md5(self, mdkey):
    """
    MD5加密
    mdkey:需要加密地key
    """
    new_md5 = md5()
    # 这里必须用encode()函数对字符串进行编码,不然会报 TypeError: Unicode-objects must be encoded before hashing
    new_md5.update(mdkey.encode(encoding='utf-8'))
    # 加密
    return new_md5.hexdigest()
