keyobject.asymmetricKeyType crashes on C++ assertion
A followup discussion to #26319
We're still crashing here on any unhandled key. e.g:
-----BEGIN PRIVATE KEY-----
MC4CAQAwBQYDK2VuBCIEILD/13Y5R/tmcCjZVSooIcpfGvZxf+qt6dMu5FYaOC1a
-----END PRIVATE KEY-----
This makes the API rather unstable since end-users can force key material that will crash the process. Developers have no way to detect this other than parsing the key material before sending it to create(private|public)Key, kinda killing the KeyObject point.
The sane thing here would be return "unsupported"
/"unknown"
or to not instantiate the KeyObject at all and throw in JS instead.
Returning unsupported
is enough for libraries using KeyObjects to check if they want to accept the key.
