Shared, copied and unfinished secrets
keytally reuse takes the .env files of the folder, or the files you name, and the example file for comparison. A secret value found in two files is an error, because a leak of staging then opens production. A placeholder such as changeme or <your-key>, or a value still equal to the one in .env.example, is an error. One value behind two keys of a file and a secret under eight characters are warnings. Secrets are picked out by key name (PASSWORD, TOKEN, SECRET, API_KEY and similar, but not PUBLIC_KEY or SITE_KEY) and by long random-looking or URL-embedded values.
