We have added new tools to our online hacking tools collection. All of our online tools run directly in the browser and don’t send data anywhere. If you work with bug bounties, networks, code, or CTF challenges, you may find something useful here.
New Security & Network Tools
Email Header Analyzer
Paste raw email headers and see how the message moved across different servers. The tool checks SPF, DKIM, and DMARC results and highlights signs of spoofing. It also points out the sending IP address.
Security Headers Checker
Drop in your server’s HTTP response and get a quick look at the security headers in place. It reports missing items such as HSTS, CSP, X-Frame-Options, and others. Each missing header comes with a short note on what it does.

Bcrypt Hash Generator
Create bcrypt hashes with an adjustable cost value. You can also test a password against an existing hash. All of the work is done locally in the browser.
CIDR Visualizer
Enter a CIDR block and get the network address, broadcast address, mask, and usable host range. A binary layout shows which bits belong to the network part.
Chmod Calculator
Toggle read, write, and execute permissions and watch the octal and symbolic forms update. Common presets such as 755 and 644 are available.
Developer Tools
ASCII / Unicode Converter
Convert between text, hex, binary, decimal, and Unicode code points. Handy for CTFs or quick format changes. An ASCII table is included for reference.
Port Reference Guide
Look up common TCP and UDP ports. Search by number or filter by category. Useful during firewall setup or reconnaissance work.
HTTP Status Code Reference
Covers status codes from 100 to 511 with short explanations. Codes can be sorted by category or searched directly.
cURL Command Builder
Assemble cURL commands without typing them by hand. Set the method, headers, body, and other options, then copy the finished command.
Regex Tester
Enter a pattern and a test string. Matches appear immediately. Flags like case-insensitive or multiline can be toggled. A few common patterns are included for quick tests.
QR Code Generator
Create QR codes for URLs, text, WiFi details, or email actions. Size and colors can be adjusted before downloading the image.
CTF & Cryptography Tools
ROT13 & Caesar Cipher
Shift text by any value from 1 to 25. The tool can also show all rotations at once, which helps when dealing with unknown shifts.
Vigenère Cipher
Encrypt or decrypt using a keyword. A table shows how each letter changes based on the key.
XOR Cipher
XOR text with a key supplied in ASCII or hex. A brute-force option tries all single-byte keys and highlights readable output.
Brainfuck Interpreter
Run Brainfuck programs in the browser and watch memory values update. A few sample snippets are included.
Morse Code Translator
Convert text to Morse or decode Morse back to text. There is also an audio mode with adjustable speed and tone.
Why We Have Created Such Tools?
Many people prefer browser-based utilities that do not store input or require accounts. Everything here works offline once loaded, and the code runs on the user’s device.
If you have an idea for a tool that should be added to the list, feel free to suggest it.
