A simple API for working with the Mac OS X keychain.
The API is designed for you to work with the keychain based on key/value pair matching.
This is a further distilation of how things work with the new Snow Leopard APIs for accessing the keychain. Ideally things now work in a much more Rubyish way than they would had you used the originally set of C functions.
There are 4 categories of key/value pairs that you combine to make queries.
this is a mandatory field; but
mr_keychaincurrently will automatically add a class of KSecClassInternetPassword for you (since that is the only supported class right now).
- Item Attributes; there can be zero or more of these.
- Search filters; there can be zero or more of these.
there must be at least one of these, but more can be
specified. However, most methods in
mr_keychainwill set the return type for you and prevent you from overriding.
# get an item item = Keychain::Item.new # add some search criteria, you need at least one, options are listed # in the keychain services reference 'Attribute Item Keys and Values' # section (link above) item.attributes.merge!( KSecAttrProtocol => KSecAttrProtocolHTTPS, KSecAttrServer => 'github.com' ) # work with the entry if it exists if item.exists? # cache all the metadata and print the account name (user name) puts item.metadata![KSecAttrAccount] # print the password (needs authorization) puts item.password # change the password and check it (BE CAREFUL) puts item.password = 'test' # change the user name and save to the keychain # note how you do not need authorization to change the user name item.update!( KSecAttrAccount => 'test' ) puts item.metadata[KSecAttrAccount] else puts 'No such item exists, maybe you need different criteria?' end
- Make the simple cases simpler
- Allow more succinct names for constants and guess the actual values
- Allow deleting of keychain items
The APIs that this library depends on can only access to internet passwords right now. The interface should remain the same when/if it is expanded to include the other types of items that the keychain holds.
In order to run the tests on your system, you need to have a specific dataset already installed into your keychain; I will eventually document the details of this required fixture.
- Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
- Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
- Fork the project
- Start a feature/bugfix branch
- Commit and push until you are happy with your contribution
- Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
- Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
