# Azure Key Vault Certificates SDK for Rust Client library for Azure Key Vault Certificates — secure storage and management of certificates. ## Installation ```sh cargo add azure_security_keyvault_certificates azure_identity ``` ## Environment Variables ```bash AZURE_KEYVAULT_URL=https://<vault-name>.vault.azure.net/ ``` ## Authentication ```rust use azure_identity::DeveloperToolsCredential; use azure_security_keyvault_certificates::CertificateClient; let credential = DeveloperToolsCredential::new(None)?; let client = CertificateClient::new( "https://<vault-name>.vault.azure.net/", credential.clone(), None, )?; ``` ## Core Operations ### Get Certificate ```rust use azure_core::base64; let certificate = client .get_certificate("certificate-name", None) .await? .into_model()?; println!( "Thumbprint: {:?}", certificate.x509_thumbprint.map(base64::encode_url_safe) ); ``` ### Create Certificate ```rust use azure_security_keyvault_certificates::models::{ CreateCertificateParameters, CertificatePolicy, IssuerParameters, X509CertificateProperties, }; let policy = CertificatePolicy { issuer_parameters: Some(IssuerParameters { name: Some("Self".into()), ..Default::default() }), x509_certificate_properties: Some(X509CertificateProperties { subject: Some("CN=example.com".into()), ..Default::default() }), ..Default::default() }; let params = CreateCertificateParameters { certificate_policy: Some(policy), ..Default::default() }; let operation = client .create_certificate("cert-name", params.try_into()?, None) .await?; ``` ### Import Certificate ```rust use azure_security_keyvault_certificates::models::ImportCertificateParameters; let params = ImportCertificateParameters { base64_encoded_certificate: Some(base64_cert_data), password: Some("optional-password".into()), ..Default::default() }; let certificate = client .import_certificate("cert-name", params.try_into()?, None) .await? .into_model()?; ``` ### Delete Certificate ```rust client.delete_certificate("certificate-name", None).await?; ``` ### List Certificates ```rust use azure_security_keyvault_certificates::ResourceExt; use futures::TryStreamExt; let mut pager = client.list_certificate_properties(None)?.into_stream(); while let Some(cert) = pager.try_next().await? { let name = cert.resource_id()?.name; println!("Certificate: {}", name); } ``` ### Get Certificate Policy ```rust let policy = client .get_certificate_policy("certificate-name", None) .await? .into_model()?; ``` ### Update Certificate Policy ```rust use azure_security_keyvault_certificates::models::UpdateCertificatePolicyParameters; let params = UpdateCertificatePolicyParameters { // Update policy properties ..Default::default() }; client .update_certificate_policy("cert-name", params.try_into()?, None) .await?; ``` ## Certificate Lifecycle 1. **Create** — generates new certificate with policy 2. **Import** — import existing PFX/PEM certificate 3. **Get** — retrieve certificate (public key only) 4. **Update** — modify certificate properties 5. **Delete** — soft delete (recoverable) 6. **Purge** — permanent deletion ## Best Practices 1. **Use Entra ID auth** — `DeveloperToolsCredential` for dev 2. **Use managed certificates** — auto-renewal with supported issuers 3. **Set proper validity period** — balance security and maintenance 4. **Use certificate policies** — define renewal and key properties 5. **Monitor expiration** — set up alerts for expiring certificates 6. **Enable soft delete** — required for production vaults ## RBAC Permissions Assign these Key Vault roles: - `Key Vault Certificates Officer` — full CRUD on certificates - `Key Vault Reader` — read certificate metadata ## Reference Links | Resource | Link | |----------|------| | API Reference | https://docs.rs/azure_security_keyvault_certificates | | Source Code | https://github.com/Azure/azure-sdk-for-rust/tree/main/sdk/keyvault/azure_security_keyvault_certificates | | crates.io | https://crates.io/crates/azure_security_keyvault_certificates | ## When to Use This skill is applicable to execute the workflow or actions described in the overview. ## Limitations - Use this skill only when the task clearly matches the scope described above. - Do not treat the output as a substitute for environment-specific validation, testing, or expert review. - Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
