Mesh Drop

English | 中文

Simple, fast LAN file transfer tool, built with Wails and Vue.

Features

• File Transfer: Support multi-file sending, easily share.
• Folder Transfer: Support sending entire folder structures.
• Text Transfer: Quickly sync text content between devices.
• Encrypted Transmission: Ensure data security during transmission.
• Secure Identity: Ed25519-based signature verification to prevent spoofing.

Security Mechanisms

Mesh Drop uses a multi-layered security design to protect users from potential malicious attacks:

1. Identity

   • Each device generates a unique pair of Ed25519 keys on first startup.
   • All presence broadcasts are signed with the private key.
   • The receiver verifies the signature with the public key to ensure the identity has not been tampered with.

2. Trust

   • Uses TOFU (Trust On First Use) strategy.
   • Users can choose to "Trust" a Peer. Once trusted, that Peer's public key is pinned.
   • Subsequent packets from that Peer ID must be verified by the saved public key, otherwise they will be marked as Mismatch.
   • Anti-spoofing: If someone tries to spoof a trusted Peer ID, the UI will display a clear "Mismatch" security warning and prevent metadata from being overwritten.

3. Encryption

   • File transfer service uses HTTPS protocol.
   • Automatically generates self-signed certificates for communication encryption to prevent eavesdropping.
