Curated list of awesome lists
Awesome Crypto Papers
A curated list of cryptography papers, articles, tutorials and howtos for noncryptographers.
Notes
The goal of this list is to provide educational reading material for different levels of cryptographic knowledge. I started it because my day job onboarding engineers at Cossack Labs includes educating them in cryptographic matters and giving advise what to read on specific topics, and that involves finding the same materials repeatedly. Hopefully, it will be useful for someone else as well.
It is aimed at people who are using cryptography in higherlevel security systems to implement database encryption, secure sharing, endtoend encryption in various schemes, and should understand how it works, how it fails and how it is attacked. It is not a list of notable / important / historically important papers (although many of them are here). It is not aimed at academics (who have better grasp of what they need anyway), nor it is aimed for systematic study of wannabe cryptographers (who better follow structured approach under professional guidance).
It will be extended gradually as I find something of "musthave" value. Pull requests are very welcome.

Math

PRIMES is in P  Unconditional deterministic polynomialtime algorithm that determines whether an input number is prime or composite.
Postquantum cryptography
Books
That seems somewhat out of scope, isn't it? But these are books only fully available online for free. Read them as a sequence of papers if you will.
Lectures and educational courses
Online crypto challenges
Not exactly papers, but crypto challenges are awesome educational material.
