This simple application allows safely keep passwords for browser using only one master key.

For each website a user should provide alias, url and login. Based on url, login and secret master-key, an
automatical 64 symbols password is generated using sha256 algorithm. The usage of master-key and hash
functions forces the password to be almost random sequence of numbers and letters a-f. A line containing
alias, url, login and generated password is added to password.gpwd file, while encrypted master-key is saved
in master-key.gpwd file. The cryptography part is based on cryptography and hashlib packages and graphical
interface relies on CustomTkinter package.

We recommend a master-key to be at least 15 symbols to safely encrypt passwords, such length should prevent
against brut-force-methods. Only numbers, capital and lowercase letters are allowed for master key.

                    login already exists, nothing will be added. Master-key is neccessary for this operation.
