TL;DR: Filarr prioritizes privacy with zero-knowledge encryption. Dropbox prioritizes features and collaboration. Choose Filarr if security is your top priority.

Encryption: The Fundamental Difference

Dropbox: Server-Side Encryption

Your Device → Upload File → Dropbox Servers → Encrypt → Storage
                                    ↓
                            Dropbox Has Keys
                            Can Decrypt Anytime

What this means:

• Files uploaded in plaintext
• Dropbox encrypts on their servers
• Dropbox holds encryption keys
• Employees can technically access your files
• Law enforcement can request access

Filarr: Client-Side Zero-Knowledge Encryption

Your Device → Encrypt Locally → Upload → Storage
      ↓                                      ↓
  You Keep Keys              Filarr Stores Encrypted Blob
                             Cannot Decrypt (No Keys)

What this means:

• Files encrypted before upload
• You control encryption keys
• Filarr cannot access your files
• Even employees cannot decrypt
• Nothing to give law enforcement

Real-World Impact

Scenario: Government Data Request

Dropbox:

Government → Warrant → Dropbox Complies → Your Files Disclosed

Filarr:

Government → Warrant → Filarr Has Only Encrypted Data → Cannot Comply

Example: In 2022, Dropbox complied with 87% of government data requests (Transparency Report). With Filarr's zero-knowledge encryption, there's nothing to disclose.

Performance Comparison

Upload Speed

// 1GB file upload benchmark

Dropbox: {
  plainUpload: '~5 seconds',
  serverEncryption: '+0.5s',
  total: '5.5 seconds'
}

Filarr: {
  clientEncryption: '+2 seconds',
  encryptedUpload: '~5 seconds',
  total: '7 seconds'
}

Verdict: Dropbox is ~25% faster due to no client-side encryption. Filarr's encryption overhead is minimal with modern hardware.

Search Performance

Dropbox: Instant server-side search Filarr: Client-side encrypted search (requires local index)

Example:

Query: "contract 2024"

Dropbox:
  - Search server → Results in under 100ms
  - Can search any text in files

Filarr:
  - Download encrypted index → Decrypt → Search
  - Results in ~500ms
  - Only searches encrypted metadata + filenames

GDPR Compliance Comparison

Filarr

✓ Zero-knowledge encryption (Article 32) ✓ Data minimization by default ✓ EU data centers only ✓ No data analysis (can't see your data) ✓ Crypto-shredding for instant deletion ✓ One-click data export

Breach scenario: Even if breached, data is encrypted with keys Filarr doesn't have. May not require breach notification (Article 34).

Dropbox

~ Encryption at rest (Article 32) ~ International data transfers (US company) ~ Data analysis for features (requires consent) ~ Standard deletion (not instant) ~ Data export available

Breach scenario: 2022 breach exposed source code and internal data. User files were encrypted but Dropbox holds keys.

Technical Deep Dive

Encryption Implementation

Dropbox:

# Server-side encryption (simplified)
def store_file(file):
    # File arrives unencrypted
    encrypted = aes256_encrypt(file, server_key)
    # Server keeps key
    store(encrypted, server_key)

Filarr:

// Client-side encryption
async function storeFile(file: File, userPassword: string) {
  // Derive user's key (never sent to server)
  const userKey = await deriveKey(userPassword)

  // Encrypt locally
  const encrypted = await aes256gcm(file, userKey)

  // Upload encrypted blob
  await upload(encrypted)
  // Server never sees key or plaintext
}

Sharing Encrypted Files

Filarr's approach:

async function shareFile(fileId: string, recipientEmail: string) {
  // 1. Get file's encryption key
  const fileKey = await getFileKey(fileId)

  // 2. Get recipient's public key
  const recipientPubKey = await getPublicKey(recipientEmail)

  // 3. Encrypt file key with recipient's public key
  const encryptedFileKey = await rsaEncrypt(fileKey, recipientPubKey)

  // 4. Share encrypted key
  await shareEncryptedKey(fileId, recipientEmail, encryptedFileKey)
}

Recipient can decrypt with their private key, maintaining zero-knowledge.
