They SHOULD use the algorithm id, I presume.
Maybe we can make this a stronger requirement or recommendation
for the future. I something believe that we should be able to change
the string representation without major problems at least at major revisions.
Third party applications would then need to adjust.

This makes two assumptions that this code should not do, once it does not use
the algo id and secondly it uses internal knowledge of what this string will
lead do, aka guessing the keysize. I believe a lot of the design should be
done that frontends to not do too much guessing here, otherwise they will
have to expect to change sooner or later.
