Cryptographic Identity
for AI Agents

SSL certificates for the AI agent economy. Post-quantum secure DIDs and verifiable credentials that let your AI agents prove who they are, what they can do, and who authorized them.

AI agents have no identity

Today's AI agents operate with API keys and bearer tokens — shared secrets that can be stolen, leaked, or impersonated.

  • No cryptographic proof of agent identity
  • No capability boundaries or permission scoping
  • No audit trail of delegated authority
  • Classical crypto vulnerable to quantum computers

AstraCipher: SSL for agents

Give every AI agent a cryptographic identity — a W3C DID with post-quantum keys and verifiable credentials defining what it can do.

  • DIDs: Unique, verifiable identity per agent
  • Credentials: Signed capability boundaries
  • Trust Chains: Delegated authority with depth limits
  • PQC: ML-DSA-65 + ECDSA P-256 hybrid signing

Built for the agent economy

Everything you need to secure autonomous AI agents at scale

🔑

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.

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.

Trust Chains

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

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...

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);
