  "service": "<fullname>AWS Key Management Service</fullname> <p> AWS Key Management Service (KMS) is an encryption and key management web service. This guide describes the KMS actions that you can call programmatically. For general information about KMS, see (need an address here). For the KMS developer guide, see (need address here). </p> <note> AWS provides SDKs that consist of libraries and sample code for various programming languages and platforms (Java, Ruby, .Net, iOS, Android, etc.). The SDKs provide a convenient way to create programmatic access to KMS and AWS. For example, the SDKs take care of tasks such as signing requests (see below), managing errors, and retrying requests automatically. For more information about the AWS SDKs, including how to download and install them, see <a href=\"http://aws.amazon.com/tools/\">Tools for Amazon Web Services</a>. </note> <p> We recommend that you use the AWS SDKs to make programmatic API calls to KMS. However, you can also use the KMS Query API to make to make direct calls to the KMS web service. </p> <p><b>Signing Requests</b></p> <p> Requests must be signed by using an access key ID and a secret access key. We strongly recommend that you do not use your AWS account access key ID and secret key for everyday work with KMS. Instead, use the access key ID and secret access key for an IAM user, or you can use the AWS Security Token Service to generate temporary security credentials that you can use to sign requests. </p> <p> All KMS operations require <a href=\"http://docs.aws.amazon.com/general/latest/gr/signature-version-4.html\">Signature Version 4</a>. </p> <p><b>Recording API Requests</b></p> <p> KMS supports AWS CloudTrail, a service that records AWS API calls and related events for your AWS account and delivers them to an Amazon S3 bucket that you specify. By using the information collected by CloudTrail, you can determine what requests were made to KMS, who made the request, when it was made, and so on. To learn more about CloudTrail, including how to turn it on and find your log files, see the <a href=\"http://docs.aws.amazon.com/awscloudtrail/latest/userguide/whatiscloudtrail.html\">AWS CloudTrail User Guide</a> </p> <p><b>Additional Resources</b></p> <p>For more information about credentials and request signing, see the following:</p> <ul> <li> <a href=\"http://docs.aws.amazon.com/general/latest/gr/aws-security-credentials.html\">AWS Security Credentials</a>.
