rustls-libssl is a partial reimplementation of the OpenSSL 3 libssl ABI. It is written in rust and uses rustls. It does not replace libcrypto: this is still required.
This project is experimental. We have aimed for the subset of libssl used by:
- curl on Ubuntu 22.04 LTS
- nginx on Ubuntu 22.04 LTS and 24.04 LTS
We have a compatibility matrix and known issues.
$ wget https://github.com/rustls/rustls-openssl-compat/releases/latest/download/rustls-libssl_amd64.deb
$ sudo dpkg -i rustls-libssl_amd64.debUsing curl:
$ with-rustls-libssl curl https://google.com/with-rustls-libssl just sets LD_LIBRARY_PATH and executes the given process.
Using nginx:
$ sudo rustls-libssl-nginx enable
$ sudo systemctl daemon-reload
$ sudo service nginx restartrustls-libssl-nginx enable installs a systemd drop-in in /etc/systemd/system/nginx.service.d/.
rustls-libssl-nginx disable undoes that.
