With the changes starting after version 7.3.3, the introduction of the CryptoModule system silently removes all encryption for React Native users even when a cipherKey value is passed. Essentially, the legacy crypto object is set up, but all underlying functionality relies on a crypto module being defined. As such, React Native users passing in a cipherkey are unknowingly falling back to unencrypted communication, which creates a security risk and is likely not the intended behavior.

I would like to propose:

• Have the React Native entrypoint continue to respect the cipherKey configuration value and use the prior (legacy) encryption system

• Update the documentation to note that the legacy behavior can be opted into, or a custom method must be used on RN. This way users are not inadvertently defaulted into plaintext communication (this is very unlikely to be their expectation when passing in a cipherKey)

I have code changes under test for the first bullet and will be happy to submit them if you are willing to consider this approach. I believe it would be best for users to retain some level of encryption if they were previously relying on it, while providing a clear recommendation path to enhanced encryption in documentation.
