looks like I'll need to parse the keyParams... which can be done in a non-breaking fashion by adding properties to the string 😬
spec:
https://tools.ietf.org/html/rfc4568#section-6.1
which includes test vectors.
Needs to deal with this which is probably an extension (in sessionParam)

hrm. Looks like adding properties to the string isn't possible even. So this will have to be a separate method.
