Security & Utility tools help with practical tasks like generating strong passwords, hashing text, creating QR codes, and working with colors. These tools are useful for website admins, developers, designers, and everyday users who want quick, reliable results without installing extra apps.

Use Password Generator to create strong random passwords for accounts and services. Hash Generator lets you create MD5/SHA hashes for verification or development workflows (note: hashes are not encryption). QR Code Generator creates scannable codes for links, Wi-Fi details, contact info, and more. Color tools (picker and HEX↔RGB converter) are perfect for UI design, brand color matching, and CSS work.

Whenever you’re working with security-related data, keep best practices in mind: never share private passwords, and don’t rely on MD5 for secure storage in modern systems. These tools are meant to support workflows, not replace professional security measures.

FAQ

  • Are generated passwords secure? They are random; you should still store them safely (password manager).

  • Is hashing the same as encryption? No. Hashing is one-way; encryption is reversible with a key.

  • Can I use QR codes for URLs? Yes — paste a URL and export the QR image.

  • Which color format should I use for CSS? HEX is common; RGB is helpful for effects and opacity.
