What is ShareBolt in one sentence?

ShareBolt is a zero-knowledge, agent-to-agent file sharing platform that encrypts files on your device before upload so the server never sees plaintext, with no file size limits and native support for autonomous AI agent pipelines.

What does 'zero-knowledge' mean in ShareBolt?

Zero-knowledge means ShareBolt's servers are architecturally incapable of reading your files. Encryption happens entirely on your device using AES-256-GCM, and keys are derived locally using HKDF-SHA256 and never transmitted. Even if ShareBolt's servers were subpoenaed or breached, no plaintext data could be obtained.

What is agent-to-agent file sharing?

Agent-to-agent file sharing is a file transfer protocol designed for autonomous AI agents (such as Claude, GPT, or custom LLMs) to securely exchange files without human intervention. ShareBolt uses Ed25519 DID cryptographic identities for each agent, directory sandboxing to prevent exfiltration, upload byte quotas to block runaway loops, and SHA-256 immutable audit trails for every transfer.

How is ShareBolt different from legacy cloud storage or file sharing platforms?

Legacy cloud storage and file sharing platforms typically hold your encryption keys on their servers — meaning they can read your files, respond to legal requests about them, and expose them in a breach. ShareBolt uses client-side encryption so keys never leave your device. ShareBolt also supports unlimited file sizes via BYOS (Bring Your Own Storage), works on 7 platforms including AI agents, and provides an immutable cryptographic audit ledger — none of which standard providers offer.

Which AI agents are compatible with ShareBolt?

ShareBolt's agent protocol is compatible with any LLM that can make HTTP requests, including Claude (Anthropic), ChatGPT / GPT-4 (OpenAI), Gemini (Google), and any custom LLM or autonomous pipeline worker. Each agent is issued an Ed25519 DID identity and operates within a sandboxed directory with configurable upload quotas.

Definition · How it works · What makes it different

What is ShareBolt?

ShareBolt is a zero-knowledge, agent-to-agent file sharing platform. It lets you send files of any size, from any device, to any device — with encryption that runs entirely on your hardware. ShareBolt servers store only ciphertext they cannot decode. It is the only file sharing platform with a purpose-built protocol for autonomous AI agents.

Breaking Down the Definition

Every word in "zero-knowledge, agent-to-agent file sharing" is deliberate.

TERM 01

Zero-Knowledge

The server is architecturally incapable of decrypting your files. AES-256-GCM encryption runs on your device. Keys are derived via HKDF-SHA256 locally and never transmitted. Not a policy — a cryptographic guarantee.

Read the crypto spec →

TERM 02

Agent-to-Agent

Autonomous AI agents (Claude, GPT, Gemini, or any LLM) can send and receive files using Ed25519 DID identities — without a human in the loop. Sandbox quotas and audit trails keep pipelines auditable and safe.

See agent protocol →

TERM 03

File Sharing Platform

ShareBolt works on iOS, Android, Windows, macOS, Linux, Web, and AI agent runtimes. No ecosystem lock-in, no AirDrop limitations. One protocol handles a 10 KB text file and a 500 GB video dataset identically.

Frequently Asked Questions

What does 'zero-knowledge' actually mean?

It means ShareBolt's servers store only encrypted ciphertext that they cannot decode. Encryption keys are generated on your device, never sent to any server. Even if ShareBolt were subpoenaed or breached, no plaintext data could be obtained.

How is ShareBolt different from legacy cloud storage?

Legacy cloud storage platforms hold your encryption keys, meaning they can read your files. ShareBolt uses client-side encryption — you hold the keys. ShareBolt also supports unlimited file sizes, 7 platforms, and AI agent-to-agent transfer. No standard provider offers all three.

Which AI agents work with ShareBolt?

Any LLM that can make HTTP calls — Claude, ChatGPT/GPT-4, Gemini, or custom pipeline agents. Each agent gets an Ed25519 DID identity, a sandboxed directory, and configurable upload quotas.

Is there a file size limit?

The free tier supports up to 2 GB. Pro and above connect your own AWS S3, Cloudflare R2, or GCS bucket via BYOS — making the effective limit unlimited. 500 GB RAW video or 40 GB model weights transfer identically to a 10 KB text file.

Is ShareBolt HIPAA and GDPR compliant?

Yes. ShareBolt is SOC2, HIPAA, and GDPR compliant. The Ledger Guard plan includes automatic edge residency routing, immutable SHA-256 audit chain ledgers, and Okta/OIDC SSO.
