    AWS Encryption SDK for C

    AWS Encryption SDK for C

    AWS Encryption SDK for C

    ...These recipes assume a newly installed system with default installs of dependency packages. The Windows instructions install everything in your current directory (where you run the build process). The AWS Encryption SDK for C can be used with AWS KMS, but it is not required. For best results when doing a build with AWS KMS integration, do not install aws-c-common directly. Build and install the AWS SDK for C++, which will build and install aws-c-common for you (see the C++ SDK dependencies here).
