Generate JWT Secret Env

Generate JWT_SECRET in .env

Workflow

1. Resolve target files and preconditions.

   • Require a repository root with a readable src/ directory.
   • Require a writable .env file; create .env only if it is missing and the task asks to initialize environment values.
   • Preferred reference check:
     • rg -n --glob "src/**" "JWT_SECRET"
   • Accept reference patterns such as:
     • config.get('JWT_SECRET')
     • ConfigService.get('JWT_SECRET')
     • process.env.JWT_SECRET
   • Stop without editing .env if no src/ reference exists.

2. Inspect .env and determine whether generation is needed.

   • Parse lines and locate active (non-comment) JWT_SECRET= entries.
   • Generate only if:
     • Key is absent, or
     • Value is empty (JWT_SECRET=, JWT_SECRET="", JWT_SECRET=''), or
     • Value is exactly change-me-in-production (with or without quotes).
   • Do not overwrite any other non-placeholder value.
   • If multiple active keys exist, update only the first eligible active key by default.

3. Generate a cryptographically secure secret.

   • Preferred Node command:
     • node -e "console.log(require('crypto').randomBytes(32).toString('base64'))"
   • Accept equivalent secure output formats (hex is also valid) when randomness comes from a cryptographically secure source.

4. Update .env safely.

   • If an active JWT_SECRET= line exists and is empty/placeholder, replace only its value.
   • If no active key exists, append JWT_SECRET=<generated> in a sensible auth/env section.
   • Preserve unrelated lines, comments, spacing style, and key order.
   • If duplicate active keys exist, update only the first active eligible key and leave the rest unchanged unless the task explicitly asks for cleanup.

5. Perform security checks.

   • Confirm .env is ignored by git (.gitignore or equivalent ignore rules).
   • Confirm no command output, logs, or summaries expose the generated secret value.
   • Never print the generated secret in summaries unless the user explicitly asks for it.
   • If .env is tracked by git and the task is to harden security, recommend rotating the leaked secret after ignore rules are fixed.

6. Run deterministic verification gates.

   • Re-scan src/ references and confirm they still resolve to JWT_SECRET.
   • Confirm .env now has an active JWT_SECRET= entry with a non-empty, non-placeholder value.
   • Report one of these outcomes:
     • updated (secret generated and written),
     • unchanged-valid (existing non-placeholder secret kept),
     • skipped-no-reference (no src/ usage),
     • blocked (missing permissions/files or other hard blocker with exact cause).
