X509 Certificates Handling
The cryptoauthlib library streamlines X.509 certificate management for Microchip CryptoAuthentication devices. It provides APIs to generate, parse, sign, and verify X.509 certificates, utilizing secure key storage and cryptographic operations performed by the hardware.
The library abstracts ASN.1 DER encoding/decoding and certificate structure, enabling secure creation and processing of certificates without exposing private keys outside the device. This facilitates robust device authentication, provisioning, and mutual TLS for embedded and IoT applications.
cryptoauthlib supports efficient encoding and decoding of X.509 certificates, including compressed certificate formats to reduce memory and bandwidth usage. This enables secure certificate storage and transmission in resource-constrained environments while maintaining X.509 compatibility.
