comment Plain text size limits for AES-GCM mode just 64GB?
The machines are 'just' 200,000 or 200k ... typo on my part by also putting in the 'k'. I can't edit that old comment now but sorry for the excitement :)

comment Plain text size limits for AES-GCM mode just 64GB?
Chunking was the first on our mind but there are $200,000K+ machines before and after this pipeline stage which expect one file. That limitation is also modeled (not by us) into the larger architecture :( ... chunking would involve many vendors so is practically not possible

comment Why is a Feistel network bijective?
Ok, as soon as I edited my question it came to me, the different input (B0) continues to propagate down on the side ... need coffee!

comment Why is a Feistel network bijective?
The round function (Fk) can be block cipher or hash based and we pick a subset of output bits into the next round. A collision at say, Fk(n,T,0), in round zero would then map two inputs at the top to a single input at the bottom, right?

comment Why is the P-521 elliptic curve not in Suite B if AES-256 is?
Makes sense, thanks for the reference. Although by the timing Kevin might put me in the crypto purist group, I excuse myself from it as a crypto pragmatist. The question comes to (my) mind less as grumbling but more as a crypto anomaly design curiosity ...
