Choosing the right secret format
Use Hex key (32 bytes = 256 bits) or Base64url key for HMAC signing secrets (JWT_SECRET, NEXTAUTH_SECRET, AES-256 keys). For database passwords embedded in connection strings or URLs, use Random password with URL / conn-string safe symbols enabled so characters like ;, @, / or ? never break parsing.
