Verify vault secret integrity in unauthenticated I/O streams (audit log, STDOUT/STDERR via the systemd journal) by scanning the text with Vault Radar. We search for both known and unknown secrets by using an index of KVV2 values and also by radar's built-in heuristics for credentials, secrets, and keys.
The verification has been added to many scenarios where a slight time increase is allowed, as we now have to install Vault Radar and scan the text. In practice this adds less than 10 seconds to the overall duration of a scenario.
In the in-place upgrade scenario we explicitly exclude this verification when upgrading from a version that we know will fail the check. We also make the verification opt-in so as to not require a Vault Radar license to run Enos scenarios, though it will always be enabled in CI.
As part of this we also update our enos workflow to utilize secret values from our self-hosted Vault when executing in the vault-enterprise repo context.
