Hi Behcet:
I think it carries a little bit too far to try and discuss algorithm
agility considerations on this list (here, with SHA-2 hash function
family vs. SHA-3). Please see [1] and info on the so-called SHA3 hash
function contest (which ran from ~2009 to 2013) one can find online and
in [1] itself.
I hope this helps you navigate this.
Rene

Hi Rene,
What is sha3?
What happened to sha2? Is sha2 out now?
Why do we need a new sha every now and then?

Hi Carsten:
Thanks for the support.
One can download my Sage code, some conversion functions, and
examples via the link below. The conversion functions follow
Appendix I of the lwig curve draft.
Please contact me *offline* if you wish to discuss.

Hi Rene,
thank you for doing this work.
One question comes to mind:

I implemented all SHA3 functions from scratch on the bit-level and had this
vetted independently via contacts at NIST.
Is this implementation available?
Has it been upstreamed to Sage?
