Generates deterministic passwords

This is inspired by spectre.app but simpler. This uses a sha256 hashed combination of username + password + service to generate the same password, thus eliminating the need to store, maintain and back up other generated passwords.

jpedro.github.io/master has the browser experience.

The used service name list is kept under the file ~/.config/master/list.txt (or whatever MASTER_LIST points to) purely for autocompletion, which will be added later.

Eventually, the idea is to create a simple browser extension that uses the URL domain name as the service.

pip install masterpass

Yes, yes. The package is called masterpass but the binary is called master. To be fixed after #2582 is resolved.

$ master --help

NAME
    master -- Generates deterministic passwords for services

USAGE
    master NAME                 Gets the password for service NAME
    master -l, --list           Lists all stored services
    master -r, --remove NAME    Removes service NAME from the stored list
    master -v, --version        Shows the version
    master -h, --help           Shows this help

Using these default settings, it will generate a password that's 41 characters long. 6 chunks of 6 character long with 5 separators in between.

Note [1] If you don't set the MASTER_USERNAME or the MASTER_PASSWORD you will be prompted for them.
