This repo provides a C API for AWS Nitro Enclaves, including a KMS SDK that integrates it with attestation. The simplest way to use this SDK is by using one of the available containers as a base. Note that this SDK is currently not supported on Windows. Only the client-side sample application (kmstool_instance) is supported on Windows. If you discover a potential security issue in the Nitro Enclaves SDK for C, we ask that you notify AWS Security via our vulnerability reporting page.
