Job description
I have Java application sources without documentation, the application consists of many programs and modules, only the fragment responsible for authorization / update from the https: path is required
You also need to create a simple web authorization mechanism that saves successful and failed logins in the login database,
preferably in conjunction with SMTP (if the user has a valid e-mail account - the application starts / if not and incorrect authorization repeatedly e.g. 10x in a row - deletes files on the disk).
