HashKey: Secure Passwords

Secure Passwords, Built Locally.

HashKey is a powerful, offline-first utility designed to help you generate strong passwords and understand the mechanics behind digital security. Built with privacy at its core, HashKey operates entirely on your device. No internet connection required, and zero data collected.

Whether you want to create an unbreakable password or learn about cryptographic strength, HashKey provides the tools you need in a clean, single-screen interface.

Features:
- Advanced Password Generator: Customize the length and character sets (uppercase, lowercase, numbers, symbols) to generate highly secure passwords instantly.
- Brute-Force & Entropy Estimations: Understand the true strength of your passwords. HashKey provides theoretical estimates of how long a brute-force attack would take to crack your password, along with detailed entropy calculations.
- Cryptographic Hashes: See how your generated password translates into standard cryptographic hashes like SHA and MD5, using Apple's native frameworks.
- 100% Offline & Private: Your data never leaves your device. HashKey does not track, store, or transmit any of your keystrokes or generated passwords.
