The Envoy OpenSSL Extensions project hosts extensions for building Envoy purely with OpenSSL.
The Envoy OpenSSL Extensions project is governed by the Apache License, Version 2.0. See the LICENSE file for the full license text.
To build OpenSSL-enabled Envoy run
$ CXXFLAGS="-DENVOY_SSL_VERSION=\\\"OpenSSL\\\"" bazel build //:envoy --define boringssl=disabled
If you need OpenSSL dynamically linked to Envoy then re-map @boringssl to
@openssl_shared by editing the WORKSPACE file.
