+# dynamic-preauth
+
+I had an idea that executables could be pre-authenticated by the server before being ran, with no interaction from the user.
+
+This is a proof of concept of that idea, built in Rust.
+
+## How it works
+
+1. The server is provided a fully built template executable on startup.
+
+2. Users can 'authenticate' themselves and then download the executable.
+
+3. Before the executable is served to the user, the server will inject the user's authentication token into the executable by modifying the binary.
+
+4. The modified binary is then served to the user.
+
+5. A constant time string in the binary, now modified, is used to authenticate the binary's requests to the server.
+
+## Implementation
+
+- The testing binary is built in Docker, and is a simple Rust binary that sends a GET request to the server with the authentication token.
