🔀 URL Obfuscator & Decoder Tool

🌐 Overview

A dual-purpose web tool that provides:

• Obfuscation: Convert URLs/IPs into various security-safe formats
• Decoding: Reverse obfuscated URLs back to their original form

Perfect for security professionals, threat analysts, and IT teams who need to safely share potentially malicious links in reports or communications.

✨ Key Features

🔒 Obfuscator

• Multiple obfuscation formats:
  • hxxp://example[.]com
  • hxxps[:]//example[.]com
  • example [dot] com
  • e x a m p l e . c o m (spaced format)
• Two processing modes:
  • URLs-only (extracts and obfuscates just URLs/IPs)
  • Full-text (processes entire text while obfuscating detected URLs/IPs)
• Supports:
  • Full URLs (http://, https://)
  • Bare domains (example.com)
  • IP addresses (192.168.1.1)

🔓 Decoder

• Reverses common obfuscation techniques:
  • hxxp → http
  • [.] → .
  • [dot] → .
  • Removes spacing patterns
• Input validation to prevent double-decoding

🛠️ Technologies Used

• Frontend:
  • Bootstrap 5 (responsive design)
  • Vanilla JavaScript
• Core Functionality:
  • Regular expressions for pattern matching
  • Clipboard API for copy functionality
• No backend required (runs entirely in browser)

🚀 Usage Guide

Obfuscation

1. Paste text/URLs in the left panel
2. Select obfuscation format
3. Choose processing mode:
   • URLs-only: Extracts and obfuscates just URLs/IPs
   • Full-text: Processes entire text while obfuscating detected URLs/IPs
4. Click "Convert"
5. Copy results with "Copy to Clipboard"

Decoding

1. Paste obfuscated URLs in the right panel
2. Click "Decode"
3. Copy clean URLs with "Copy to Clipboard"

🔧 Core Functions

encoder.js

• convertUrls(): Main obfuscation function
• URL detection regex patterns:
  • Complete URLs
  • Bare domains
  • IP addresses
• Formatting handlers for each obfuscation type

decode.js

• decodeUrls(): Main decoding function
• Pattern replacement for common obfuscation techniques
• Input validation to prevent unnecessary decoding

💡 Use Cases

• Security Reporting: Safely share malicious URLs in reports
• Threat Analysis: Process IOC lists with different obfuscation formats
• Forensics: Decode obfuscated URLs found in investigations
• Training: Demonstrate common URL hiding techniques

⚠️ Limitations

• Decoder may not handle all custom obfuscation schemes
• Complex nested obfuscations might require multiple passes
• Spaced format (e x a m p l e . c o m) decoding is basic

🌟 Future Enhancements

• Add more obfuscation formats
• Implement batch file processing
• Add URL validation checks
• Create browser extension version
