OpenSSL source is maintained by a team of committers. The overall project is run by the OpenSSL Management Committee We operate under a set of project bylaws and ask everyone to follow our code of conduct.
Here are some of the ways you can join the community and contribute; see the links on the right-hand side. The Getting Started has some ideas. We maintain several mailing lists. Anyone can join, but you must be a member of a list to post to it. We have a public wiki, and anyone can request an account and start adding content. We have a team blog, where members of the development team will occasionally post.
While we only distribute source, some members of the community make binaries available.
Finally we'also like to thank several groups for help with the project infrastructure over time.
