zero-share

• A client-side secure P2P file sharing solution using WebRTC technology

• Key Features:

  • Enables parallel transfer of multiple files
  • Generates SDP connections for WebRTC data channels
  • Serverless architecture (only uses public STUN servers for ICE candidates)
  • Implements PGP encryption for additional security
  • Responsive UI with QR code scanning and clipboard paste functionality
  • Uses [sdp-compact](https://github.com/ntsd/sdp-compact fa-solid fa-up-right-from-square) for shortened SDP

• How It Works:

  • Uses ICE protocol to establish direct peer connections through NAT
  • Secures transfers with DTLS and adds PGP encryption (RSA-OAEP-1024, AES-128) as a second layer
  • Example workflow:
    1. Offer generates link → sends to answer
    2. Answer opens link → sends response
    3. Offer accepts → secure file transfer begins

• Target Audience:

  • Users needing secure, direct file transfers without server intermediaries
  • Developers interested in WebRTC implementations

• Known Limitations:

  • Potential firewall blocking during transfers
  • Performance may vary depending on STUN server availability

• Open Source:

  • MIT Licensed
  • Accepts community contributions following Conventional Commits

Note: While built with Svelte, framework implementation details are secondary to the core WebRTC functionality.
