Lucas Gabriel Vuotto f511cddf0d Fix _ctx_new and _ctx_free implementations They both will only alloc and free the internal _ctx structs. Get rid of the void argument for new and only pass arg to _free instead of the whole lc__ctx struct.		2024-06-06 11:45:30 +00:00

=========

> 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
  - [/] compare: returns `0` if match, non-`0` otherwise. The non-`0`
    case might leak information. Would be better to return `0xffffffff`
    if match, `0` otherwise.

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

- [x] Poly1305
- [ ] SHA-512 (needed for Ed25519)

Ciphers
-------

- [x] ChaCha20
- [ ] XChaCha20

AEAD
----

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

ECC
---

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

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

Utilities
---------

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

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?
