+# @peculiar/attestation-common
+
+A common module providing tools and interfaces for verifying HSM attestation files from various HSMs, including support for certificate chain validation and attestation data extraction.
+
+## Installation
+
+To install the library, use npm:
+
+```sh
+npm install @peculiar/attestation-common
+```
+
+## Usage
+
+This example demonstrates how to use the common attestation interfaces and types:
+
+```typescript
+import { X509Certificate, PublicKey } from "@peculiar/x509";
+import {
+  Attestation,
+  AttestationVerificationParams,
+  AttestationVerificationResult,
+  AttestationProvider,
+} from "@peculiar/attestation-common";
+
+// Example implementation of an AttestationProvider
+class ExampleAttestationProvider implements AttestationProvider {
+  format = "example";
+
+  async read(data: BufferSource): Promise<Attestation> {
+    // Implement the logic to read attestation data
+    return {
+      format: this.format,
+      publicKey: new PublicKey(/* public key data */),
+      metadata: {
+        /* metadata */
+      },
+    };
+  }
+
+  async verify(
+    params: AttestationVerificationParams
+  ): Promise<AttestationVerificationResult> {
+    // Implement the logic to verify attestation data
+    return {
+      status: true,
+      chain: params.intermediateCerts,
+      signer: params.intermediateCerts[0],
+    };
+  }
+}
+
+// Example usage
+const provider = new ExampleAttestationProvider();
+
+// Example attestation data and certificate chain data
+const attestationData = new Uint8Array([
+  /* attestation data bytes */
+]);
+const certChainPem = `-----BEGIN CERTIFICATE-----
+MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA7V1...
+-----END CERTIFICATE-----
+-----BEGIN CERTIFICATE-----
+MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA7V1...
+-----END CERTIFICATE-----`;
+
+// Read the attestation data
+const attestation = await provider.read(attestationData);
+
+// Decode the certificate chain
+const certBlobs = x509.PemConverter.decode(certChainPem);
+const certs = certBlobs.map((blob) => new x509.X509Certificate(blob));
+
+// Verify the attestation using the provided certificate chain
+const result = await provider.verify({
+  attestation,
+  intermediateCerts: certs,
+});
+
+console.log(result);
