The Cryptographer's Codex
An opinonated introduction and general resource for those interested in cryptography
Contents
| Q | A |
|---|---|
| Not sure if cryptography is your thing? | Start with the introductory beginner series of challenges, they're a short series of 4 challenges that go from nothing to solving some real cryptography challenges |
| Wanting to learn more about cryptography? | Work on cryptopals and follow the companion guide! |
| Done both and looking for more? | Take a look at cryptohack for more challenges that cover additional topics like elliptical curves |
| Want more low level systems-like cryptography? | Take a look at Block Breakers for a guided series on attacking block ciphers themselves |
| Prefer lecture style lessons instead of getting hands on with challenges? | RPISEC has a bunch of streamed lectures covering a number of cryptography concepts. (If anyone has any textbook recommendations feel free to open a PR on the repo) |
| Interested in building out your cryptography toolkit? | Check out some of the assorted guides |
| Want to test your skills against a set of beginner/intermediate challenges? | Try out picoCTF, an excellent beginner CTF put on by CMU |
| Already built up a foundation with cryptohack/cryptopals? | Dive straight into CTFs! Check out ctftime to get a list of upcoming events |

About
The Cryptographer's Codex is primarily consisted of challenges and documents written up by Arctic of Maple Bacon
The codex was an idea that I had when we (Maple Bacon) first hosted our beginner CTF for UBC students, SaplingCTF. The name was catchy so it stuck around and over time I built up more and more stuff that I had written up for various things so I thought I should just collect them together under site.
The end goal with the site is to have a place for us cryptographers to point interested CTF players towards, with a curated set of challenges, guides, and setup resources.
