18.1.6 The createKeyGenerator method

The createKeyGenerator method returns a new KeyGenerator object that will
generate new keys using the specified AlgorithmIdentifier. It must act as
follows:

  1. Let normalizedAlgorithm be the result of processing algorithm according to
     the algorithm normalizing rules.
  2. If normalizedAlgorithm does not describe a registered algorithm that
     supports the key generation operation, throw a NotSupportedError and
     terminate the operation.
  3. Return a new KeyGenerator object S with the following characteristics:
     1. S.result = null

Generated keys conform to the temporary, extractable, and keyUsages arguments.

Public keys are always extractable.
