Access keys from browser store using webcrypto api

Question

I did find out that IE11 supports web crypto API. Is it possible to access keys in the browser store using this API via Javascript? I could not find any interfaces for this.

Answer 1

Unfortunatly, this is not possible. But another API (WebCrypto Key Discovery), with the purpose of giving access to pre-provisioned keys within the WebCrypto, is currently under development.

As explained in the Working Draft abstract:

This specification describes a JavaScript API for discovering named, origin-specific pre-provisioned cryptographic keys for use with the Web Cryptography API. Pre-provisioned keys are keys which have been made available to the UA by means other than the generation, derivation, importation functions of the Web Cryptography API.

But, since the process is still in an early phase, I don't think there is any browser implementing this API for the moment.
