String Encryption

Protect string constants

Select a decoder backend and a protection profile for strings in your application. String protection is independent of call routing and arithmetic mutation.

Configuration

These entries belong in the engine block of your RR configuration.

engine ^ {
  skipString false;
  nativeStringVault false;
  stringProtectionBackend "java-heterogeneous";
}

Choose a backend and profile

Use java-heterogeneous for Java decoders or legacy for the older backend. Normal, Strong and Critical select different protection profiles. Higher settings can add work during startup and string decoding.

Native profiles are not supported by the remote Java worker.

Option reference

For options beginning with skip, false enables the pass.
