We have published the keystore file functionality for everyone to use.
The hope is that instead of getting several different implementations of this functionality, we can all congregate around one.

Github:
https://github.com/stellarport/stellar-keystore

npm:
https://www.npmjs.com/package/stellar-keystore

Additionally, we have had our library audited by a 3rd party dev (author of TweetNaCl.js):
https://github.com/stellarport/stellar-keystore/blob/master/audit.pdf

Enjoy!

    What is it supposed to be used for? How do I extract the key from the keystore?
    There seems to be a lot of missing functionality here.

        .keypair() I guess..

        Everything assumes I have keys stored in files, which seems a bit restrictive

            Yes, you're probably right. There should probably be a method that takes a json object (i.e file contents in json form) and returns a keypair. Then wrap that method in a method that takes a file (similar to the create methods).

              @dzham ok, updated the keypair() and publicKey() methods to accept object or blob. Also updated the readme.

                  TraA-Li Hi, sorry about that. I've published a new version, try it now.

                  p.s. you could fix that error in the future by including babel-polyfiill. The new version won't need it though.
