Azure Key Vault Certificates for Rust: Secure Certificate Lifecycle Management

Managing X.509 certificates securely at scale requires centralized storage, automatic renewal, and audited access. Azure Key Vault provides this with hardware-backed security, while the Rust SDK adds compile-time safety guarantees for certificate operations.

What This Skill Does

Provides certificate creation and import, automatic renewal policies, certificate version management, X.509 certificate retrieval, PEM/DER format support, and integration with Azure Identity for authentication.

Getting Started

cargo add azure_security_keyvault_certificates azure_identity

Create and retrieve certificates:

use azure_security_keyvault_certificates::CertificateClient;
use azure_identity::DefaultAzureCredential;

let credential = DefaultAzureCredential::new()?;
let client = CertificateClient::new(
    "https://myvault.vault.azure.net",
    credential
)?;

// Get certificate
let cert = client.get_certificate("my-cert").await?;

Key Features

Certificate Creation with custom policies and subject names. Automatic Renewal eliminates manual certificate rotation. Version Management tracks certificate history. Type Safety prevents misuse of certificate data. Hardware Security protects private keys in HSMs.

When to Use

Use for TLS/SSL certificate management, code signing certificates, client authentication, mTLS implementations, and PKI infrastructure. Avoid when local certificate files suffice for development-only scenarios.
