+browserify-sign
+===
+
+a package to duplicate the functionality of node's crypto public key functions, much of this is based on [Fedor Indutny's](https://github.com/indutny) work on [tls.js](https://github.com/indutny/tls.js).
+
+# done
+
+- basic rsa signing and verifying with the right api
+
+# todo
+
+- tests to make sure we actually did it
+- chinese remainder theorom?
+- eliptical curve signing
+- publicEncrypt and privateDecrypt?
