Usage Examples

Download Torrent with Encryption

downloader = TorrentDownloader()
downloader.start_aria2()

# Download torrent
downloader.download_torrent(
    "magnet:?xt=urn:btih:...",
    output_name="my_file"
)

# Encrypt and upload to Drive
downloader.encrypt_and_upload(
    "/content/downloads/my_file",
    password="secure_password",
    cleanup_source=True
)

Encrypt Local Files

from AzuDL_GC2GD_v1.5.0_COMPLETE_COLAB import FileEncryptor

encryptor = FileEncryptor()

# Encrypt
encryptor.encrypt_file(
    "/path/to/file",
    "/path/to/file.enc",
    password="secure_password"
)

# Decrypt
encryptor.decrypt_file(
    "/path/to/file.enc",
    "/path/to/file",
    password="secure_password"
)

Configure Security Level

from AzuDL_GC2GD_v1.5.0_COMPLETE_COLAB import CONFIG_PRESETS

# Maximum privacy (slower)
preset = CONFIG_PRESETS["privacy_maximum"]

# Balanced (recommended)
preset = CONFIG_PRESETS["privacy_balanced"]

# Performance-focused
preset = CONFIG_PRESETS["privacy_performance"]

Storage Structure

AzuDL creates the following folder structure in Google Drive:

/MyDrive/AzuDL-GC2GD/
├── TorrentDownloads/
├── YouTubeDownloads/
├── DirectDownloads/
├── BatchDownloads/
├── GitHubDownloads/
├── Archives/
└── Logs/
    ├── aria2.log
    ├── aria2.session
    ├── azudl_YYYYMMDD_HHMMSS.log
    └── blocklists/

Configuration

Aria2 Configuration

Default configuration includes:

bt-require-crypto=true          # Mandatory encryption
bt-min-crypto-level=arc4        # Minimum arc4 encryption
bt-force-encryption=true        # Force all connections
bt-max-peers=55                 # Limit peer connections
enable-dht=true                 # DHT enabled
enable-peer-exchange=true       # PEX enabled

Blocklist Support

Automatic IP blocklist downloads from:

Level 1: Spyware, adware, throttlers
Level 2: Malware, trojans, botnets
BadPeers: Malicious peers, honey pots

Encryption Algorithm

Algorithm: AES-256-GCM
Key Derivation: PBKDF2-SHA256
Iterations: 100,000 (OWASP compliant)
Authentication: HMAC-SHA256

Security Considerations

✓ Do's

Use strong passwords (16+ characters, mixed case, symbols)
Store passwords in secure password manager
Encrypt sensitive files before uploading
Keep session logs secure
Use privacy-focused presets for sensitive content

✗ Don'ts

Don't share passwords via email/chat
Don't disable BT encryption
Don't trust unverified torrent sources
Don't leave Colab notebooks unattended
Don't commit credentials to Git

Limitations

Google Colab Timeout: Colab may disconnect idle sessions
File Size Limits: Google Drive API has rate limits
Bandwidth: Shared Colab resources may throttle transfers
Legal: Only download content you have rights to download
