In today’s digital landscape, network security and cryptography are no longer optional—they’re fundamental skills every developer needs. Whether you’re building web applications, securing APIs, or working with blockchain technology, having the right tools at your fingertips can make all the difference.
1. Port Scanner
Understanding what ports are open on your servers is crucial for security auditing and network troubleshooting. The Port Scanner tool allows you to quickly scan target hosts or IP addresses for open TCP ports.
Key Features:
- Scan common ports (20, 21, 22, 80, 443, 3306, etc.)
- Custom port range scanning
- Service identification for well-known ports
- Configurable timeout settings
Whether you’re verifying firewall rules or checking for unauthorized services, this tool provides instant visibility into your network exposure.
2. WHOIS Lookup
Need to find out who owns a domain or when it expires? The WHOIS Lookup tool queries domain registration information directly from WHOIS databases.
What you’ll discover:
- Registrar information
- Registration and expiration dates
- Name servers
- Domain status codes
- Raw WHOIS data for advanced users
This is invaluable for competitive research, domain acquisition, or verifying website legitimacy.
3. Bitcoin Address Validator
Working with cryptocurrency applications? The Bitcoin Address Validator helps you verify Bitcoin addresses and identify their types.
Supported address types:
- P2PKH – Legacy addresses starting with 1
- P2SH – Multisig addresses starting with 3
- Bech32 – SegWit addresses starting with bc1
Validate addresses before transactions to prevent costly errors and improve user experience in your crypto applications.
4. XOR Encryptor
Sometimes you need simple, reversible encryption for data obfuscation. The XOR Encryptor applies XOR cipher encryption and decryption with a custom key.
Use cases:
- Simple data obfuscation
- Challenge-response protocols
- Learning cryptography fundamentals
- Quick encoding/decoding tasks
While XOR encryption isn’t suitable for sensitive data protection, it’s perfect for lightweight obfuscation and educational purposes.
5. PBKDF2 Generator
Proper password hashing is essential for any application that stores user credentials. The PBKDF2 Generator creates cryptographically secure derived keys using the PBKDF2 algorithm.
Features:
- Multiple hash algorithms (SHA-256, SHA-512)
- Configurable iteration counts
- Customizable salt and key length
- Industry-standard key derivation
PBKDF2 is recommended by NIST for password storage and is widely supported across frameworks and languages.
