revised Is the logic for how the enigma machine worked documented somewhere?
Links needed a description, which I added. (The answer still looks like a link-only answer or comment.)

Linked to papers.

comment How is the MD2 hash function S-table constructed from Pi?
"these numbers do not seem to match up with the first bytes of pi." They do not match up with the "first bytes" of PI because only a fractional part of PI was used. Remember that for a positive number written in decimal notation, the fractional part corresponds to the digits appearing after the decimal point.

comment How is the MD2 hash function S-table constructed from Pi?
Because it was never stated which range of PI was used, and because it was never stated which calculation (if any) was involved while extracting the bits/bytes, and because PI is known to be infinite, it's pretty senseless to try reverse-engineering that s-table unless you want to spend the rest of your life brute-forcing fractions of PI towards that s-table. In cases like these, if you want to learn how to reconstruct the table, you'll have to ask the creator of that s-table (or work for a governmental agency).

comment How is the MD2 hash function S-table constructed from Pi?
It's a mystery to me why no one ever asked the creator of that s-table. When weird things show up in RFCs, someone like me expects the crypto-pros to speak up and ask. But we have to remember that crypto-professionals were a bit rarer "back in the days". I'm probably expecting too much from the past.

comment Why use CBC-MAC? Why not just apply hash function on the whole message?
possible duplicate of Can I jettison MAC if I already have SHA1(M)?

I added the *homework* tag.

revised How to submit a new method of encryption?
Corrected the format so it's obvious that the 2nd paragraph is an EDIT.
