+# Python-RSA has been archived
+
+Hi folks,
+
+I'm Sybren, one of the original authors and the maintainer of this project.
+Unfortunately I don't have the time and brain space left to properly maintain
+Python-RSA. As you can see from the lack of activity on the open issues, and the
+lack of commits, that has been the case for a while now.
+
+As Python-RSA is included as a dependency in quite a few high-profile projects,
+I don't feel comfortable handing over the project to someone else. It's just too
+big of a risk.
+
+Thanks for having used this little library for so long, and in so many projects.
+I truely didn't expect that when I started working on it. Also big thanks to all
+the people helping out and improving the project.
+
+There are improvements that haven't made it into a new release. As I said, I
+don't have the time and the brain space to really investigate and oversee the
+security impact of all those changes. It's not a decision I've made lightly.
+
+So that's it. If you want to keep the project alive, please fork it. Give it the
+love it deserves, investigate those yet-unreleased improvements, and have a
+project that's then already better than how I left this one.
+
+Cheers,
+Sybren
