Technical Specification: Free Online Security.txt Generator
1. Overview
A client-side web application designed to help developers and website administrators generate valid security.txt files compliant with RFC 9116. The tool provides a user-friendly interface to input security contact details and generates a copy-pasteable, downloadable text file.
2. Core Features
- Live Preview: As the user types in the form, the
security.txtcontent updates in real-time in a read-only code block. - Field Validation: Real-time validation for email addresses, URLs, and date formats (ISO 8601) to ensure the generated file is RFC-compliant.
- Download & Copy: One-click functionality to copy the generated text to the system clipboard and download the content as a
.txtfile. - Standardized Field Support:
- Contact (Email/URL)
- Encryption (PGP Key URL)
- Acknowledgments (URL)
- Hiring (URL)
- Policy (URL)
- Preferred Languages (ISO 639 codes)
- Expires (Date picker)
- Contextual Help: Tooltips explaining each field's purpose according to RFC 9116.
3. UI/UX Layout
- Header: Simple title: "Security.txt Generator". No nav bars.
- Main Content Area: A two-column split layout on desktop (Form on left, Preview on right) and a single-column stack on mobile.
- Form Section: Grouped inputs with clean, descriptive labels and floating-label interaction styles.
- Preview Section: A stylized
codeblock with syntax highlighting (even if basic), featuring a distinct "Copy to Clipboard" button in the corner. - Footer/Bottom Section: No footer. Minimalist interface focus.
4. Color Palette (Light Mode Only)
- Primary Surface: White (
#FFFFFF) - Background: Soft Gray (
#F9FAFB) - Primary Accent: Vibrant Indigo (
#4F46E5) for buttons. - Text: Dark Charcoal (
#1F2937) for readability. - Borders/Dividers: Light Slate (
#E5E7EB). - Success/Alert: Soft Emerald (
#10B981) for confirmation toasts.
5. Technical Directives
- Architecture: Single-file HTML5 (CSS/JS embedded). Use Tailwind CSS via CDN.
- State Management: Pure Vanilla JavaScript. Store form values in a single object variable; update DOM elements via document query selectors. Do NOT use
localStorage. - Interaction: Smooth CSS transitions on all button hovers and focus states. Use custom overlay divs for modal notifications (e.g., "Copied to clipboard!").
- Security: Run in a sandboxed iframe. Ensure all external links use
rel="noopener noreferrer". - Compatibility: Ensure responsiveness via CSS Flexbox/Grid. The form must remain scrollable independently if it exceeds the viewport height on smaller screens.
- Download Logic: Use
Blob()andURL.createObjectURL()to generate the download link programmatically on the fly.
