SSL証明書の期限取得する関数です。戻ってくるのがＪＳＴではないので、調整しています。

# ssl の期限の読み込み
def get_ssl_end(domain):
    import ssl
    import OpenSSL
    import datetime
    from datetime import datetime as dt
    cert = ssl.get_server_certificate((domain, 443),
    ssl_version=ssl.PROTOCOL_SSLv23)
    x509 = OpenSSL.crypto.load_certificate(OpenSSL.crypto.FILETYPE_PEM, cert)
    return((dt.strptime(str(x509.get_notAfter())[2:16],'%Y%m%d%H%M%S')  + datetime.timedelta(hours=9)).strftime('%Y %m %d'))
