Context / Background

It's not clearly mentioned how to perform decryption in a web application that is not running inside the HardhatRuntimeEnvironment.

The only workaround i've found for now is to spawn a webserver that internally uses CLI commands to run hardhat tasks that run the encryption/decryption, and return the stdout to the webserver, which returns it to the calling website.

This is a good point — the current docs are not very clear about how decryption should be handled in web apps running outside the HardhatRuntimeEnvironment.

For developers building local or standalone web applications (e.g. React/Vue on localhost), it would be helpful to:

• Clearly document whether client-side decryption is supported or discouraged
• Explain the recommended architecture for handling decryption (backend service, trusted relayer, CLI, etc.)
• Provide an example flow for localhost development that does not rely on spawning Hardhat tasks indirectly

Right now, the workaround of invoking Hardhat CLI tasks from a backend service feels unintuitive and should either be documented as the intended approach or replaced with a cleaner solution.
