slow-libs single-header libraries

MIT licennced (see ./LICENSE)

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

Each library is documentated at the top of each header file

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

Contribution guide

• Please use clang-format (and the provided .clang-format style) If you do not want to use clang-format, try to match the code style of other existing code, and a maintainer will format your code on merge.
• Do not break portability of an existing "finished" library
• Make new libraries as portable as possible (in a reasonable amount of time)

1. the compiler might optimize the zeroing away ↩︎

2. does not prevent against length-extension, by algorithm design. See Cryptography 101. ↩︎
