Lucas Gabriel Vuotto 666b833b98 auth/hmac: complete overhaul 
Now that there are dedicated struct for initial parameters, make the
HMAC params provide a lc_hash_ctx to be used internally. This makes HMAC
less special and allows it to work with any hash, instead of needing
dedicated inits and ctx_news. As an upside, now it's possible to have a
one-pass HMAC.

lilcrypto
=========

> They see me rollin', they hatin'.

Experiment on rolling my own crypto. Kinda. I'm not creating any new
protocol, but implementing known algorithms and constructions. The main
focus is to understand how to implement the math behind the algorithms,
and to get to know the constructions better.

Algorithms
==========

Utilities
---------

- Constant-time operations
  - [x] compare

Hash
----

- [x] SHA-224
- [x] SHA-256
- [x] SHA-384
- [x] SHA-512 (needed for Ed25519)

Authentication
--------------

- [x] HMAC
- [x] Poly1305

Ciphers
-------

- [x] ChaCha20
- [x] XChaCha20

AEAD
----

- [x] ChaCha20-Poly1305
- [x] XChaCha20-Poly1305

ECC
---

- Curve25519
  - [ ] Ed25519 (EdDSA)
  - [ ] X25519 (ECDH)

Nice-to-haves
=============

Utilities
---------

- [ ] Portable Makefile
- [ ] NaCl interface
- [ ] signify interface

Hash
----

- [ ] SHA-512/224 & SHA-512/256 (most of the work done)

Authentication
--------------

- [ ] GMAC

Ciphers
-------

- [ ] AES
- [ ] Camellia
- [ ] Salsa20 (no Wycheproof test vector suite)
- [ ] XSalsa20 (no Wycheproof test vector suite)

AEAD
----

- [ ] AES-GCM
- [ ] Camellia-GCM
- [ ] Salsa20-Poly1305 (no Wycherproof test vector suite)
- [ ] XSalsa20-Poly1305 (no Wycherproof test vector suite)

KDF
---

- [ ] HKDF
