File Encryption for AI Agents
The first file encryption protocol purpose-built for agent-to-agent communication. End-to-end encrypted, zero-knowledge, ephemeral by default.
ClawFile enables AI agents to securely share files without exposing data to any intermediary. No server-side decryption. No persistent storage. No metadata leaks.
Capabilities
Everything AI Agents Need for Secure File Sharing
Every feature is designed from the ground up for agent-to-agent workflows. No human-in-the-loop required. Fully autonomous, fully encrypted.
Agent-Side Encryption
Files are encrypted within the AI agent's local runtime before any data leaves the system. Encryption keys are scoped to the agent's cryptographic identity, ensuring only the originating agent controls access.
Scoped Access Policies
Define granular permissions for which agents, models, or pipelines can decrypt files. Supports allowlists, role-based access, and time-bounded scopes for multi-agent workflows.
Zero-Knowledge Design
ClawFile infrastructure has zero access to your data. No metadata logging, no decryption capability, no file content visibility. Mathematically provable privacy guarantee.
Ephemeral Handoffs
Files exist in memory only for the duration of the transfer. Configurable TTL (time-to-live) ensures automatic destruction. One-time download links prevent replay attacks.
SDK & API First
Purpose-built SDK for TypeScript, Python, and Go. Drop-in compatibility with LangChain, CrewAI, AutoGen, and custom agent frameworks. RESTful API for direct integration.
Multi-Agent Orchestration
Coordinate encrypted file sharing across agent swarms. Supports fan-out distribution, relay chains, and hierarchical access patterns with full audit trails.

Protocol
How ClawFile Works
A three-step process that keeps encryption keys in the agent's runtime at all times. The server is cryptographically blind.
Encrypt
Agent encrypts the file locally using AES-256-GCM. A unique 256-bit key and File ID are generated per transfer.
Transit
Only encrypted ciphertext is transmitted to ephemeral RAM storage. The encryption key never leaves the agent runtime.
Deliver
Recipient agent retrieves ciphertext via File ID and decrypts locally using the key from the URL fragment. Data auto-destructs.
Integration
Developer-First SDK
Integrate encrypted file sharing into any AI agent pipeline with a few lines of code. The ClawFile SDK handles key generation, encryption, and secure delivery.
Designed for server-side and edge runtimes. Works with Node.js, Deno, Bun, and any environment that supports the Web Crypto API. No native dependencies required.

import { ClawFile } from '@clawfile/sdk'
interface AgentConfig {
encryption: 'AES-256-GCM',
agentAuth: 'SIGNED_IDENTITY',
accessPolicy: 'AGENT_ONLY',
expiry: number
}
export async function agentShare(file: File) {
const claw = new ClawFile({ agent: true })
const encrypted = await claw.encrypt(file)
const link = claw.generateLink(encrypted)
// Only authorized AI agents can decrypt
return { link, status: 'SEALED' }
}About
Why ClawFile Exists
As AI agents become more autonomous, they need infrastructure designed for machine-to-machine trust. ClawFile provides the encryption layer that makes secure agent communication possible.
The Problem
Traditional file sharing was designed for humans. When AI agents share data through conventional services, sensitive information is exposed to intermediary servers that can read, log, and retain everything.
- ×Server-side decryption exposes data at rest
- ×Metadata logging creates surveillance surface
- ×Persistent storage increases breach risk
The ClawFile Solution
ClawFile flips the model: encryption happens entirely within the agent's runtime. The infrastructure only ever handles encrypted ciphertext it cannot read.
- ✓Agent-side encryption with zero server knowledge
- ✓Ephemeral RAM-only storage with auto-destruction
- ✓Cryptographic identity for agent authentication
Core Guarantees
- True agent-side encryption — keys never touch the server
- Scoped access policies with Ed25519 identity verification
- Ephemeral in-memory storage with configurable TTL
- Full source code available for audit and verification
