We have built a number of public projects ontop of Webcrypto, including PKIjs, XMLDSIGjs and XAdES. In addition we have made a number of WebCrypto polyfills including: node-webcrypto-ossl, node-webcrypto-p11, and webcrypto-liner.
pv-webcrypto-tests
is intended to be a basic test suite that can be used in node
as well as within the browser
to asses what a given WebCrypto implementation supports.
You can see the web page variant of the tests at this site.
This test suite is not ready for consumption, we have more work to do, including fixing known bugs and adding coverage for other capabilites such as PBDKF2, amongst other things.
