— now INCLUDING A LICENSING MECHANISM, while keeping the system realistic, implementable, and government-grade.


---

PHP + MySQL LINE-BY-LINE TYPING EXAM SYSTEM

(WITH LICENSING MECHANISM – SUMMARY)


---

1. Purpose

A secure, offline-capable typing examination system for government or institutional use to conduct English and Hindi (DevLys font) typing exams, with strict exam discipline, automatic recovery, legally auditable outputs, and license-based authorised usage.

Hindi typing is DevLys font only (non-Unicode). Candidates never see evaluation results.


---

2. Technology

PHP 8.x (procedural)

MySQL / MariaDB

Apache

HTML, CSS, Vanilla JavaScript

TCPDF for offline PDF generation

OpenSSL (for license verification only)


No external internet dependency after setup.


---

3. Core Rules

Candidate language (English / Hindi DevLys) is fixed by admin.

Typing is strictly line-by-line, one line at a time.

Arrow keys allowed; copy/paste fully blocked.

Typed data stored exactly as entered (no Unicode processing).

Candidates never see speed, accuracy, errors, or results.

All evaluation and reporting are admin-only.

System runs only when a valid license is present.



---

4. Licensing Mechanism (Mandatory)

License Characteristics

License file: [login to view URL]

Issued only by software owner

Digitally signed (RSA)

Time-bound (valid_from / valid_to)

Bound to installation identity (server hash)


License Verification

License is verified on:

System load

Admin login

If license is invalid or expired:

System blocks access

Shows: “System not authorised. Please contact vendor.”



License File Contents (before signing)
