During February 2026, Hawara developed server-side encryption with customer-provided keys (SSE-C) support for the Terraform state reader in the cloudposse/atmos repository. This feature enables secure remote state reads from AWS S3 buckets encrypted with user-managed keys, addressing compliance and security requirements. Hawara implemented robust key validation and error handling in Go, introduced configuration options for specifying SSE-C keys, and updated both tests and documentation to guide users through correct usage and edge cases. The work demonstrated depth in backend development, encryption, and testing, resulting in a well-integrated solution that broadens secure remote state access for Terraform users.
