Okay.  Let me offer a fingerprint proposal, then: SHA-256.  Basically,
identical to Werner's proposal, except with the full SHA-256.  That

I am a bit surprised that 5 months after the proposal and 6 weeks after
-02 we now get back to the fingerprint thing.  Given the lack of
comments I assumed we agreed on that.

Anyway, to move forward I agree to modify this and remove the
truncation.  I just pushed the commit below.


Salam-Shalom,
