Algorithms

draft list of algorithms

Updated 17th of August on the basis of Harry Halpin proposed text :

"As the API is meant to be extensible in order to keep up with future developments within cryptography and to provide flexibility, there are no strictly required algorithms. Thus users of this algorithm should check to see what algorithms are currently recommended and supported by implementations.

However, in order to promote interoperability for developers, there are a number of recommended algorithms. The recommended algorithms are: HMAC using SHA-256, RSASSA using SHA-256 hash, and ECDSA using P-256 curve and we expect implementations at the time of publication of this Recommendation to support these algorithms. To see the results of test-cases between implementations, please see the [@@Upcoming] Web Cryptography Test Cases Working Group."
