Hi! Author here. Sorry it's down. Will host on something CDNy now. Was previously on single server.

You can get the PDF for now from here: https://9d0df72831e4b345bb93-4b37fd03e6af34f2323bb971f72f0c0...

EDIT: Unfortunately I am on conference wifi, so, might take me a while.

EDIT2: Now on Github. https://crypto101.github.io/

Is this the final version?

I don't think it will be final for a long time, because I haven't really defined what "done" means. I still think what's there is useful, and provides a new, material improvement over a lot of existing books, despite not being anywhere near done. Plus, it's free :-)

For what it is worth, this hit HN about 8 months ago and garnered a healthy amount of discussion: https://news.ycombinator.com/item?id=7430946

Does anyone know how this compares to Coursera course [1] or [2] + [3]?

[1] https://www.coursera.org/course/cryptography

[2] https://www.coursera.org/course/crypto

[3] https://www.coursera.org/course/crypto2

(Author here.)

I've taken Dan's crypto class ([2]), so I think I can weigh in.

Obvious difference: not organized as a MOOC. Whether that is good or bad is up to you.

Focus difference: I think Crypto 101 is targetting applied crypto more, whereas the Coursera classes take a more classical introduction. There is nothing wrong with either approach, in my opinion. Just a difference in focus.


Udacity also has a applied cryptography, I haven't tried. but it's good if someones has feedback.

I have heard good things about [2] from colleagues. Also, Boneh is a capable cryptographer.

[3] has never been available while this seems only temporarily unavailable.

[1] is starting next week and I was considering spending time on it. I'd really appreciate any feedback from those who have taken it!

Site is dead, returns 500 as a response (which prints the Processing Failed to the screen).

Oh, thanks. At first I thought it was satirical. Maybe a jab at the imperfections of crypto implementations, but I guess I was reading too far into it.

i had the same issue --- hit refresh a couple of times and i went through

also dead :(

Sorry! Wasn't expecting the HN hordes. Temporarily moved to Github: https://crypto101.github.io/

  Processing Failed
This is cryptic all right. Now I've got my crypto 101, I guess.

Sorry, man. Wasn't expecting the HN flood :) I've put it on Github now. Try again? https://crypto101.github.io/

Yep, the flood has subsided. It works now :)

This is a really nice overview of currently available crypto and some uses for it. Kudos to the project manager. Good job!

Thanks! Not much of a project manager though. Just me, myself and I; and of course the people who have contributed patches through Github :)

Sounds good, I'd love to see more such hackers opening up on cryptography...

I've been looking for something like this for ages, thank you very much.

"Processing Failed"

Just hit refresh. Server does not seem happy with the attention from HN

Reddit calls it "the hug of death". Quite fitting imho.
