# Purpose: Create a time-limited gateway URL for phpMyAdmin on Virtuozzo LLSMP.
|
||||
# Usage: create_pma_gateway.sh --validity=30 [--slug=myalias]
|
||||
# Outputs: Prints the generated URL.
|
||||
#
|
||||
# SECURITY FEATURES:
|
||||
# - Input validation prevents path traversal and injection attacks
|
||||
# - Secret key handling avoids shell expansion vulnerabilities
|
||||
# - HMAC-signed tokens with time-based expiration
|
||||
# - Automatic SSL certificate detection and configuration
|
||||
# - Comprehensive rewrite rules for phpMyAdmin protection
|
||||
# - Secure cookie-based access control
|
||||
# - Self-destructing gateway files
