- Setting up peer-to-peer file sharing with trusted agents
- Sending files through Telegram, Discord, Slack, or any text-based channel
- Need chunked transfer with integrity verification
- Transferring large files using IPFS fallback

Features
- 🔗 Message-based: Transfer files through existing chat channels
- 📦 Chunked transfer: Split large files into small pieces (48KB chunks)
- ✅ Integrity verification: SHA-256 hash for chunks and files
- 🤝 Request/Accept: Explicit acceptance or auto-accept policy
- 🔒 Security: Trusted peer whitelist with secrets
- ⏰ Secret TTL: Set expiry time for trust relationships
- 🔄 Resume: Resume interrupted transfers from last chunk
- 🌐 IPFS Fallback: Use IPFS for files exceeding chunk threshold
Protocol
OCFT messages use a 🔗OCFT: prefix with Base64-encoded JSON, allowing file transfers over any text-based channel.
Limitations
- Chunk size: 48KB (safe for Base64 in messages)
- Default max file size: 100MB (configurable via
set-max-size)
- Designed for text-based channels
- IPFS fallback requires provider setup (Pinata, Filebase, or local Kubo)
