About

Hi! I'm a cybersecurity enthusiast who likes turning fiddly, command-line security and developer chores into fast, free web tools. What started as a small set of password-recovery and hash utilities has grown into a large collection of browser-based tools for developers, system administrators, penetration testers, digital forensics analysts, and students.

The guiding principle is simple: everything runs in your browser. Your files, keys, hashes, tokens, and configs are processed locally with JavaScript and WebAssembly and are never uploaded to a server. That makes these tools safe to use on sensitive data and fast to use anywhere, on desktop or mobile.

What you'll find here

Encryption & ciphers: AES, RSA, DES/3DES, ChaCha20-Poly1305, Blowfish, RC4, XOR, and classic ciphers (ROT, Affine, Bacon, Morse).
Hashing, checksums & HMAC: MD-, SHA-1/2/3, Keccak, SHAKE, BLAKE2/3, CRC, and bcrypt variants, plus a streaming file checksum/integrity verifier and a generic HMAC generator and verifier.
Encoding & converters: Base64, URL, HTML, Punycode/IDN, hash and file-signature identifiers, and data-format converters such as JSON, XML, and TOON.
Application password decryptors: recover stored credentials from tools like DBeaver, FileZilla, WinSCP, mRemoteNG, MobaXterm, Navicat, HeidiSQL, VNC, TeamViewer, Jenkins, Openfire, Cisco Type 7, Juniper Type 9, Oracle SQL Developer, and many more.
Hash extraction for cracking: John the Ripper modules (zip2john, ssh2john, office2john, pdf2john, rar2john, 7z2john, gpg2john, kdbx2john, bitlocker2john, luks2john, truecrypt2john, dmg2john) and hashcat converters.
Security & forensics: a .git secret scanner, a pickle / ML-model scanner, an offline SAM + SYSTEM NT-hash extractor, a Firefox/Thunderbird password decryptor, and a MikroTik RouterOS backup tool.
Developer & web3 utilities: a JWT decoder, editor and attack toolkit, an Ethereum ABI encoder/decoder, an ABI-to-Solidity interface generator, QR-code generators, and assorted text utilities.

New tools and improvements are added regularly based on feedback from the developer and security communities. If something is missing, broken, or could be clearer, I'd love to hear about it.

A note on responsible use: several of these tools are intended for digital forensics, password recovery on your own systems, and authorized security testing. Please only use them on data and systems you own or have explicit permission to assess.

Thanks for visiting, and stay safe and secure!
