During June 2025, Cfir contributed to the hashicorp/terraform-provider-azurerm repository by developing customer-managed encryption key support for Azure Kusto clusters. This work involved extending the provider’s resource schema and logic to allow users to specify either Azure Key Vault Key IDs or Managed HSM Key IDs for encryption at rest, enhancing security and compliance for Kusto resources. Cfir implemented these changes using Go and Terraform, focusing on seamless integration with Azure’s key management infrastructure. The feature addressed both creation and read paths, ensuring robust handling of key identifiers and aligning the provider with Azure’s encryption best practices for cloud infrastructure.
