Books
=======

* "Handbook of Elliptic and Hyperelliptic Curve Cryptography"
  Cohen and Frey https://www.hyperelliptic.org/HEHCC/
  An excellent reference for ECC math, algorithms, and side channels

* "Post-Quantum Cryptography" Bernstein, Buchmann, Dahmen
  Covers code, lattice, and hash based cryptography

Standards
============

* IEEE 1363 http://grouper.ieee.org/groups/1363/
  Very influential early in the library lifetime, so a lot of terminology used
  in the public key (such as "EME" for message encoding) code comes from here.

* ISO/IEC 18033-2 http://www.shoup.net/iso/std4.pdf
  RSA-KEM, PSEC-KEM

* NIST SP 800-108
  http://csrc.nist.gov/publications/nistpubs/800-108/sp800-108.pdf
  KDF schemes

* NIST SP 800-90A
  http://csrc.nist.gov/publications/nistpubs/800-90A/SP800-90A.pdf
  HMAC_DRBG, Hash_DRBG, CTR_DRBG, maybe one other thing?
