Not to mention how often thclaims are made despite thier sounding like
alchemy and astrology, cultish, religious,
authoritarian, scientistic, recruitment
for arcane pursuit of unsolvable mysteries, and hardly applicable to the long
and varied history of cryptology suffused with bizarre claims, subterfuge,
deception, betrayal, treachery, obligatory prevarication, inherent cheating,
diabolical misrepresentation of trustworthiness, venomous accusations
against competitors, unrestrained dupery and duplicity against the unwary,
citizen and royalty alike.
Nor that mathematics is a modern innovation in cryptology and remains
its weakest element due to inability of its applicators to wed it to code
and hardware without recourse to alchemy and astrology favored by
promoters, sales and PhDs who dream of math as golden key to natsec.
QODE, QED.

https://github.com/kjsisco/qode If you feel
overwhelmed by the sarcasm directed your way,
there is a reason for that. Designing
cryptosystems is *hard*. No, that's too mild. Is
*mindblowingly* hard. It doesn't start with
code. It starts with a mathematical description.
No, even that is not true: It starts with years
and years of study. The denisens of this list
have seen a hundred cryptosystem crash and burn.
Some of them were designed by very clever
people. Did I mention that designing
cryptosystems is hard? Don't even think of
trying it, not unless you have first spent a few
years studying the state of the art. Sorry to be
so blunt, but I think it will save you a whole
lot of grief. â Harald
