python2.7 AES 加解密（工具類）

先安裝包

pip install pycrypto==2.6.1

if __name__ == '__main__':
    encrypt = ASEUtil.encrypt('hhhhhhhhhhhhhhhh', '{"abc":"abc"}')
    decrypted = ASEUtil.decrypted('hhhhhhhhhhhhhhhh',encrypt)
    print(decrypted)

該代碼僅支持python2，注意，key只能爲16位或者16位的倍數，否則報錯

ValueError: Incorrect AES key length (15 bytes)
