The program uses a well-known principle: passwords are not stored anywhere, to generate all passwords, one master password is used, which is entered by the user.
After starting the program in the menu "File" -> "Open File" you need to select a file with logins. After selecting a file, the program displays buttons corresponding to individual services. When you click on any button, the corresponding login is copied to the clipboard and a window appears with the message: "Please copy login now". When you click on the "OK" button in the message window, a password is generated and copied to the clipboard.
File with logins has the following format:
name_on_button_1;login_1;name_of service_or_site_1
name_on_button_2;login_2;name_of service_or_site_2
name_on_button_3;login_3;name_of service_or_site_3
Password generation principle:
- The master password, login and name of the service (website) are combined together into a string.
- SHA512 conversion is performed on this line.
- Letters, numbers and special characters are selected from the resulting byte sequence, which form a new string.
- If this new string meets the password requirements (length, presence of certain characters), then it becomes the password. Otherwise, the cycle of conversions is repeated over the new string.
