Project Proposal: CycleGuard v1.0
Introduction: CycleGuard aims to be a leading privacy-focused menstrual health tracker, providing accurate predictions and insightful data without compromising user privacy. This proposal outlines the core features and development strategy for its initial release.
Objectives:
- Develop an intuitive mobile application for cycle tracking.
- Implement robust algorithms for period and ovulation prediction.
- Ensure all user data remains strictly on the user's device.
- Provide an accessible, open-source codebase for community review.
Key Features:
- Daily logging of period, symptoms, and moods.
- Calendar view with predicted cycle phases.
- Customizable reminders for period and fertility windows.
- Data export functionality.
Technology Stack: To be determined, focusing on privacy-preserving frameworks.
SHA-256 Hashing: Password Strength, Salting & Rainbow Table Defense
Type in a password below. Instantly see its unique SHA-256 hash, get real-time strength feedback, and observe how a random 'salt' dramatically changes the hash. Try common passwords to see a simulated "rainbow table" check in action!
Unsalted Password Hash:
Combined Input (Password + Salt) SHA-256 Hash:
Password Strength:
Why this matters for your privacy:
- One-Way Street: Notice how you can't easily figure out the original password from the hash? That's by design! Websites store hashes, not your actual password, for security.
- Avalanche Effect: See how changing just one character (in either password or salt) completely scrambles the hash? This means if someone tries to tamper with data, its hash will immediately reveal the change.
- Salting for Super Security: The 'salt' is a *unique, random string* added to your password *before* hashing. Even if two people use the exact same password, with different salts, their stored hashes will be completely different! This is critical for protecting against "rainbow table" attacks.
- Rainbow Table Defense: Websites like freerainbowtables.com provide pre-computed lists of common password hashes. These tables allow attackers to instantly look up the original password if they get your database's unsalted hashes. Our simulated check demonstrates this vulnerability. **Salting ensures that even if your password is in such a table, its unique salted hash prevents a quick lookup.**
- Strength vs. Hash: A strong password makes it incredibly hard for computers to guess your original input. The hash itself will always be the same length, but the *difficulty* of breaking it relies on your password's complexity and length. The estimated crack time shows just how much!
