Learn some math.

SIKE was known to be breakable since at least 1997, specific breaking algorithms were developed in 2000, and these were implemented in Magma (a symbolic algebra suite from John Cannon, Sydney Uni, second generation after the original Cayley system of the mid 1980s).

It wasn't a choice that would have been put forward by people in the abstract algebra game - just something put forward as a 'candidate' by security researchers.

Something something Venn diagrams.

Little rude, he was just asking a question.

Learn some decency.

Learn some math, more specifically learn abstract algebra | read current papers in the field, befriend people active in the field that have taken over from Charles Leedham-Green, George Havas, et al is good practical advice to avoid using methods already known for decades to be weak.

It answers the question.

Little rude, given the question asked was answered.
