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
