AES explanation before DES? Why? It doesn't make any sense.
... because the only way to introduce ciphers is, what, chronologically? Why? And why does that make it superficial?

AAMOF, I've never seen a more shallow explanation of AES... and I find it rather superficial for this reason. Man, that's nice you have written a book, now plant a tree, have a baby, and relax... take a constructive review on your work. Use it to improve that version.
Your feedback isn't really actionable. How is the author supposed to use anything about your feedback to "improve that version"?
Started reading it, pretty good so far! Only thing, why did you choose to introduce block cipher modes in the stream cipher chapter? This makes little sense to me.
It actually makes a lot of sense for practical purposes. This probably looks strange to you because most introductory cryptography texts strictly segregate stream and block ciphers. The standard pedagogical style bifurcates modern symmetric encryption into one of these two categories and talks about things like synchronization, on-the-fly encryption, speed, error correction, etc. between the two. In point of fact, th…
I don't think there have been any new designs for a good while that didn't. RC4 is, I think, the last actual stream cipher that saw widespread use (apart from designed-as-broken telco crypto). The same observation can be made for classified crypto, where they used to use bit-stream ciphers like Walburn or Saville (efficient, relatively low gate count hardware implementation) but pivoted to block ciphers since the ~80s.
Oh interesting. I recently got "Applied Cryptography" in one of the nostarchpress sales. I expected it to be turbo technical and way outside my league but popped it open on a whim one day. So far it's incredibly accessible, does anyone have thoughts on that versus this course? Worth taking the course after I finish Applied cryptography?

Every entry in CAESAR that I've studied is either based on a block cipher or a hash function. A lot of them use AES internally, but others (MORUS, NORX) used their own designs.
There are no RC4-esque stream ciphers being taken seriously these days, for good reason.

No Starch's "Serious Cryptography", the JP Aumasson book, is strong.

Hi! I'm the author. Happy to answer questions.
Do you intend to complete this book at some indeterminate point in the future?
Is there anything that any of us can do to help make it happen?
