dstash is a Dart binding for the Stash library. It enables encrypted data storage and exchange. Similar to traditional systems, Stash offers controlled access with a security model inspired by Unix permissions. Unlike traditional storage, the access is based on cryptographic features, enabling distributed control.

Features

Stash offers convenient

It supports Android, iOS, macOS, Linux and Windows on the common architectures for each OS.

Getting started

Run flutter pub get dstash or dart pub get dstash from your terminal. Alternatevely add dstash dependency in your pubspec.yaml file.

The package only contains the dart source code. You still need to download the binary libraries (depending on the target architecture) from http://github.com/stregato/stash and copy to the subfolders for your architecture, i.e. linux, ios, macos, android, windows.

The script http://github.com/stregato/stash/dart/install.sh automatically download the libraries and place them in the correct folder in your dart project. Folders for the target environments (e.g. macos, android) must be already in your project. You can run the script from the terminal at the folder where your dart project is with the Unix command

bash <(wget -qO- https://raw.githubusercontent.com/stregato/repo/stash/dart/install.sh)

Usage

    loadstashLibrary();
    
    var i = Identity('Admin');
    var db = DB.defaultDB();

    var url = 'file:///tmp/${i.id}/sample';
    var s = Safe.create(db, i, url);

    var groups = s.getGroups();
    expect(groups, isNotNull);

    var alice = Identity('Alice');
    groups = s.updateGroup('usr', Safe.grant, [alice.id]);
    expect(groups['usr']?.contains(alice.id), true);

    groups = s.getGroups();
    expect(groups['usr']?.contains(alice.id), true);

    var keys = s.getKeys('usr');
    expect(keys, isNotNull);

    s.close();
    db.close();
