Problem: Using the WebCrypto APIs developers are not able to check if the UA supports a specific crypto algorithm before they use it. They are forced to try an algorithm operation, catch the exception if the algorithm is not supported, and then try something else. This development pattern seems inefficient.

Request: Provide an API that allows developers the ability to verify if a specific algorithm is supported by the UA before they create an operation. The API would only verify if the algorithm specified is supported or not, true or false return value. It wouldn't return a list of algorithms supported by the UA.
