[Python-Dev] Cipher implementation (such as AES) in standard library

Dear all, Have we tried cipher implementation includes AES as a standard library in the past? https://docs.python.org/3.6/library/crypto.html if possible I want to try to implement AES because famous 3rd party library is not maintained and general cipher programs should be used for multiple purpose.Though the implementation is tough, I believe this should be worth to it. In my case, I want to use AES implementation for zipfile module. Thanks and Regards, --------------- Takahiro Ono
