The AI Agent Identity Crisis
Open Source · BSL 1.1 → Apache 2.0

3 million AI agents.
No way to prove who they are.

AstraCipher is the open-source SDK that gives every AI agent a verifiable, quantum-safe identity — built on W3C DIDs, verifiable credentials, and NIST post-quantum cryptography.

The identity crisis is already here

OWASP, NIST, and industry data all point to the same conclusion: AI agent identity is the #1 unsolved security problem of 2026.

AI agents have no identity

3 million AI agents are active in the US and UK alone, with 1.5 million running without any oversight. They authenticate with API keys and bearer tokens — credentials designed for humans, not autonomous systems.

  • No cryptographic proof of who an agent is or what it is authorized to do
  • 97% of AI-breached organizations lacked sufficient access controls
  • Only 28% can trace agent actions back to a human sponsor
  • A single compromised agent can poison 87% of downstream decisions within 4 hours

Verifiable identity for every agent

AstraCipher gives every AI agent a cryptographic identity — a W3C DID with post-quantum keys and verifiable credentials that define exactly what it can do, and who authorized it.

  • DIDs: Unique, globally verifiable identity per agent — no centralized registry needed
  • Verifiable Credentials: Cryptographically signed capability boundaries and permissions
  • Trust Chains: Delegated authority with depth limits — Creator → Authorizer → Agent → Sub-agent
  • Post-Quantum: ML-DSA-65 + ECDSA P-256 hybrid signing, quantum-safe today

Built for builders, trusted by security teams

Whether you are writing your first agent or securing thousands in production

🛠

Agent Developers

Building multi-agent systems on MCP, A2A, LangChain, or CrewAI? Add verifiable identity in minutes with TypeScript or Python SDKs. Your agents prove who they are without a centralized auth server.

🛡

Security & Platform Teams

Get cryptographic audit trails, trust chain enforcement, and least-privilege scoping for every agent. Trace every action back to a verified DID. Solve the non-human identity problem OWASP is warning about.

🏛

Regulated Industries

Financial services, healthcare, and government teams need traceable AI. AstraCipher's compliance engine maps agent activity to EU AI Act, DPDP, SEBI CSCRF, SOC 2, HIPAA, and GDPR requirements.

What AstraCipher gives your agents

An open-source identity stack purpose-built for autonomous AI — from cryptographic primitives to compliance reporting

🔑

Post-Quantum Cryptography

Hybrid ML-DSA-65 + ECDSA P-256 signatures. ML-KEM-768 key encapsulation. Future-proof against quantum attacks while maintaining backward compatibility with classical systems today.

Open Source
🆔

W3C Decentralized Identifiers

Every agent gets a globally unique DID with multiple verification methods. Resolve, verify, and rotate keys without centralized registries.

Open Source
📜

Verifiable Credentials

Issue signed credentials that define capabilities, permissions, and trust levels. Verify instantly without contacting the issuer.

Open Source
🔗

Trust Chains

Creator → Authorizer → Agent → Sub-agent. Delegate authority with depth limits and capability intersection.

Open Source
🛡️

Compliance Engine — 10+ Regulatory Frameworks

DPDP Act, SEBI CSCRF, EU AI Act, SOC 2, HIPAA, GDPR, NIST RMF, ISO 42001, and more. Auto-generate audit-ready compliance reports from agent activity. Available as part of the AstraCipher Platform.

Audit Trail

Cryptographically signed, append-only audit logs. Every agent action is traceable to a DID. Tamper-evident chain hashing.

Open Source
📊

Admin Dashboard

Manage agent identities, view audit analytics, export compliance reports, and configure team permissions from a centralized dashboard.

How it works

Three lines of code to give your agent a cryptographic identity

import { AstraCipher } from '@astracipher/core';

const ap = new AstraCipher({ network: 'testnet' });

// Create a post-quantum secured agent identity
const { did, didId } = await ap.createAgent({
  name: 'my-trading-agent',
  description: 'Automated trading agent for equities',
});

console.log(didId);
// did:astracipher:testnet:a1b2c3d4e5f6...

Try it live — in your browser

Real post-quantum cryptography running client-side. No server, no sign-up. Click each step to see AstraCipher in action.

AstraCipher Live Demo Ready

Click Generate Identity to create a post-quantum agent identity using ML-DSA-65 + ECDSA P-256 hybrid keys.

All cryptography runs in your browser using @noble/post-quantum and @noble/curves. Nothing is sent to any server.

Works with your stack

MCP has 97M monthly SDK downloads but no built-in agent identity. A2A connects agents but trusts you to handle auth. AstraCipher is that missing layer.

MCP Server

Expose AstraCipher identity operations as MCP tools. Any Claude, GPT, or MCP-compatible agent can create identities and verify credentials.

npx @astracipher/mcp-server

Google A2A Adapter

Full Agent-to-Agent protocol implementation. Agent Card discovery at /.well-known/agent-card.json enriched with DID and trust metadata.

import { A2AServer } from '@astracipher/a2a-adapter'

Python SDK

Async Python client with Pydantic models. Create agents, verify credentials, query audit trails. Full type hints and async support.

pip install astracipher

CLI Tool

Command-line interface for DevOps workflows. Create agents, resolve DIDs, issue credentials from CI/CD pipelines.

npx @astracipher/cli create --name my-agent

Quick start

1

Install

npm install @astracipher/core @astracipher/crypto
2

Create an agent identity

import { AstraCipher } from '@astracipher/core';
const ap = new AstraCipher({ network: 'testnet' });
const { didId } = await ap.createAgent({ name: 'my-agent' });
3

Issue credentials & verify

const cred = await ap.issueCredential({
  subjectDID: didId,
  capabilities: ['data:read'],
  trustLevel: 7,
});
const { valid } = await ap.verifyCredential(cred);
