This is a wrapper library to easily make the webcrypto capabilities available in Dart. Currently only hash functions available, where also a native Dart implementation is available.

If the selected browser does not support webcrypto API the library falls back to native Dart implementations.

Unfortunetaly the promise based webcrypto interface is not compatible with the synchronous native Hash interface.

var h = new SHA1();
h.close().then((List<int> digest){
