Android signature factory

With the handwriting of a signature program, linuxlinux ((( changes to the files in the invigilator folder, you only need to change your file suffix to unsigned.apk and add it to the monitored directory to quickly sign the file.

I hope it will be useful to those who need signatures every day.
