CLIENT-SIDE ENCRYPTION FLOW:

User Input → Paste Content
     ↓
[1] Generate AES-256 Key (random 32 bytes)
     ↓
[2] Generate IV (random 12 bytes)
     ↓
[3] Encrypt Content (AES-GCM client-side)
     ↓
[4] Extract Key Material (never sent!)
     ↓
[5] Build URL: base + #key (hash fragment)
     │
     ├─→ Send to Server: { encrypted, iv } ONLY
     │   Server stores: encrypted blob (unreadable)
     │
     └─→ Share URL: https://cybertools.cfd/paste/abc123#key
         Hash fragment (#key) NOT sent to server! ✓

RETRIEVAL FLOW:

User Clicks URL: https://cybertools.cfd/paste/abc123#key
     ↓
[1] Browser parses URL
     ├─→ Paste ID (abc123) → sent to server
     └─→ Key (#key) → kept in browser (NOT sent) ✓
     ↓
[2] Server returns: { encrypted, iv }
     ↓
[3] Client decrypts using #key from URL
     ↓
[4] Display decrypted content
     ↓
Result: Server NEVER sees plaintext ✓

SECURITY GUARANTEE:
- Server compromise → attacker gets encrypted blobs only
- Cannot decrypt without URL hash keys
- Zero-knowledge proven ✓
