The Matasano Crypto Challenges (2013)

"You get the challenges in batches of eight by emailing cryptopals at Matasano, and solve them at your own pace, in the programming language of your choice. Once you finish a set, you send in the solutions and Sean unlocks the next eight. (Curiously, after the third set, Gmail started rejecting my tarball as malware.) "

Can you still submit them for some kind of recognition? I know you can get them all now without emailing.

(FWIW I got stuck on getting an existing software package to get the correct result from encrypting via AES with a given key.)

Not really, but sort of. There's a set 8, and it's by far the best of all 8 sets (I'd rank the sets 8->6->2->3->4->7->5->1), but you have to mail Sean to get it, and you should tell him you've done at least sets 1-6.

I emailed them like 3 years ago and never heard anything. I doubt anyone monitors the mailbox anymore.

I haven't checked. Do you mean can you receive some sort of certificate of successful completion? I would think successful solutions with sharaebale code (e.g. a github repo) would be adequate for recognition of completion and competency.

I meant if they still care if you complete them.

And I thought they asked not to publish solutions?

Ah, I see. Well then, seems like it'd be good to ping them for some clarity and perhaps share the answer(s) here. :)

The nature of the challenges means you'll always know when you've solved them.
