# slow-libs single-header libraries
MIT / Public Domain (see ./LICENSE)

Most libraries are not actually slow, but that is just the naming scheme.


## Features of all libraries
- C89 (or later) compatible
- intuitive to use
- don't pollude namespace
- configurable with pre-processor macros


## Libraries
- `./chacha20.h`
- `./slowarr.h`: C templated dynamic array
- `./slowgraph.h`: WIP graph library (this is the only library that is actually slow)


## CLI Tools
CLI utils built with slow-libs.

- `./slowgraph/sgraph-adj.c`: dgtxt graphs <-> adjacency matrix


## Cryptography Security Considerations
All cryptography libraries list possible side channel attacks in their documentation

| Library      | Zeroing memory | Timing attacks | Notes |
| ------------ | -------------- | -------------- | ----- |
| `chacha20.h` | manual [^1]    | impossible     | [^2]  |

[^1]: the compiler might optimize the zeroing away
[^2]: does not prevent against length-extension, by algorithm design. See Cryptography 101.
