When enabled, Terragrunt skips checksum validation of engine files.

This can be useful during development or testing with self-developed engines.

Terragrunt currently only supports checksum validation for engines downloaded from GitHub releases, though this will change in the future.

In the meantime, download custom engines from a trusted source, verify the integrity of the engine manually, and reference the local path to the engine in your Terragrunt configuration when possible.

You must also set the [`experimental-engine`](/reference/cli/commands/run#experimental-engine) flag to use engines.
