🛡️ Advanced Security & Encryption

🔒 Client-Side Encryption

All content is encrypted in your browser using AES-256 encryption before being sent to our servers. We never see your data in plain text.

🔑 Encryption Key Management

Encryption keys are generated client-side and included in sharing links. Only users with the complete link can decrypt content.

🚫 Zero Server Access

Our servers store only encrypted data. Even system administrators cannot access your content without the decryption key.

🔥 Burn-After-Reading

• Set 1-20 access limits per content
• Automatic deletion when limit reached
• Atomic access counting prevents race conditions
• Perfect for one-time password sharing

⚠️ Access Warnings

• Warning dialogs before accessing limited content
• Visual indicators showing remaining accesses
• Confirmation prompts for final access
• Real-time access count tracking

⏰ Dual Expiration System

• Choose time-based OR count-based expiration
• Time-based: 10 minutes to 30 days
• Count-based: 1-20 access limits
• Automatic cleanup system

🔐 Encryption Standards

• AES-256 Encryption: Military-grade client-side encryption
• HTTPS/TLS 1.3: Secure data transmission
• CryptoJS Library: Industry-standard cryptographic implementation
• Key Derivation: Secure random key generation

🚫 Zero-Knowledge Architecture

• Client-Side Processing: All encryption/decryption in browser

🔒 For Maximum Security:

• Use count-based access for sensitive data
• Enable private mode for confidential content
• Share links through encrypted channels
• Use shortest appropriate expiration times
• Verify recipient before sharing

⚠️ Security Considerations:

• Complete sharing links contain decryption keys
• Count-based content deleted after access limit
• Private content requires authentication
• QR codes contain full access information
• Backup important data before sharing
