Oculus TLS extractor

The purpose of this code is to extract TLS keys from a running OVRServer_x64.exe, that sends some data to the mothership over TLS.

For details, please read the accompanying post

Note: this codebase is only intended for experimentation and documentation of reverse engineering. Using this code may cause system instability and crash your Oculus Runtime.

Building

  1. cargo build --release
  2. Copy the binaries from target/release directory.

If you want to rebuild ssl_inspector.lib, run cargo build --features=build-ssl-lib --release.

Usage

To use injector.exe as a debugger for OVRServer_x64.exe, you can use gflags or regedit. injector.exe expects path to OVRServer_x64.exe as its first argument, the rest of the arguments will be passed through to OVRServer_x64.exe.

By default, injectee.dll will log TLS keys into ssl_keylog.txt near its own location. To override secret key log location, set system environment variable SSLKEYLOGFILE. Keylog format is expected to be compatible with NSS Keylog Format.
