Passkey-PRF File Encryption with Hybrid EC P-256 Wrapping
🔗 Metanet Desktop
✅ Connected to Metanet Desktop
Your Public Key:
⚠️ Metanet Desktop not detected
Running in Passkey-only mode
🔐 Passkey Setup
Choose how you want to register your Passkey:
Platform Passkey: Uses your device's biometric authentication (Face ID, Touch ID, Windows Hello) or hardware keys. 💡 Tip: If you only see one option, click "Cancel" to see all available authenticators (including hardware keys). Security Key: Directly opens hardware key dialog (YubiKey, FIDO2 compatible devices).
🔒 Encrypt File
💡 Empfehlung: Wenn du dich selbst als Empfänger hinzufügst, kannst du die Datei später auch ohne Husky direkt in Metanet Desktop entschlüsseln!
Additional recipients can decrypt with their private keys
Hide original filename in encrypted package
🔓 Decrypt File
⚠️ SECURITY WARNING
IMPORTANT: This application will NEVER ask you for your private key during encryption!
❌ NEVER enter your private key unless you are explicitly decrypting a file that was sent to you
❌ NO legitimate window or popup from this application will ever ask for your private key during registration or encryption
⚠️ If you see any prompt asking for a private key during Passkey registration or file encryption, it is NOT from this application and is likely a phishing attempt
✅ Your private key is only needed for decryption of files that were encrypted for you as a recipient
✅ Passkeys use biometric authentication (Face ID, Touch ID, Windows Hello) - they never expose private keys
🛡️ Stay safe! If in doubt, contact the developer before entering any sensitive information.
ℹ️ How It Works
Passkey-PRF: Your device's biometric authentication derives a stable encryption key
Hybrid Encryption: File is encrypted with AES-256-GCM, then wrapped using EC P-256 ECDH
Multiple Recipients: Each recipient's public key creates a separate wrapped key
GZIP Compression: Files are compressed before encryption for efficiency
Filename Encryption: Optional encryption of the original filename for privacy
