   Want captchas for Pleroma that may be harder to crack?
   Pleroma uses a C captcha generator from huacnlee/rucaptcha on GitHub, but it’s an older version, and it has been updated to generate much stronger captchas now.

   The problem is that it’s now written in Rust, so I don’t think Pleroma devs will even think about accepting this upstream unless someone rewrites it in C/C++, but I did it anyway.

   I modified the Rust code to be a cli and output the same thing the old C stuff did (https://github.com/animeavi/rucaptcha), so it’s a drop-in replacement. If you want you can even compile this on your own PC and replace the binary in /opt/pleroma/deps/captcha/priv and be done with it.

   If you want to do it a more “proper” way, keep reading.

   You need to install Rust+Cargo first of course.

   Replace the existing :captcha in mix.exs for Pleroma with those values.

   {:captcha, git: "https://github.com/animeavi/elixir-captcha.git", ref: "d280d06ae7ba7757a772567b9e608dba3a0c0ae2"},

   Then run mix deps.get and mix compile, all that good stuff, it will take a while because Rust lol, but you can keep the instance running while it compiles, and it should just work.

   First two pics are current Pleroma captchas, last two are the new ones.
