How it works
Frameworks need a long random secret to sign sessions and tokens (Django's SECRET_KEY, Rails' secret_key_base, Laravel's APP_KEY, Express session secrets, JWT HS256 keys). 32 random bytes (256 bits) can't be guessed. Keep it out of your repository — use environment variables or a secrets manager — and rotate it if it leaks.
