The Device Identity Platform
Four integrated capabilities — certificate lifecycle, firmware signing, hardware attestation, and developer APIs — engineered to work together from manufacturing to end-of-life.
Complete Coverage. One Integration.
Each module is independently capable, but built to integrate — certificate issuance triggers a signing event; signing keys live in attested hardware; all events surface through a unified API.
Certificate Lifecycle Management
Automated provisioning, renewal scheduling, CRL/OCSP management, and revocation for device X.509 certificates. Supports ECDSA P-256/P-384 and RSA-2048/4096. One root CA hierarchy can serve millions of devices.
Deep-diveFirmware Code Signing
Sign firmware images, OTA update packages, and configuration payloads with hardware-backed keys. Verification runs on-device at boot using the embedded C SDK. Supports ECDSA, Ed25519, RSA-PSS.
Deep-diveDevice Attestation & Identity
Hardware root of trust via TPM 2.0 or Secure Element. ErlySign issues device certificates anchored to hardware identity — private keys never leave silicon. Zero-trust device onboarding with verifiable attestation chains.
Deep-diveAPI & SDK
REST API for all platform operations. Embedded C SDK (<50KB binary footprint) for constrained devices. Python SDK for manufacturing automation and CI/CD pipelines. Webhook events for real-time certificate lifecycle notifications.
