Instead, you can use the public key within AWS KMS by calling the <a>Encrypt</a>, <a>ReEncrypt</a>, or <a>Verify</a> operations with the identifier of an asymmetric CMK. When you use the public key within AWS KMS, you benefit from the authentication, authorization, and logging that are part of every AWS KMS operation. You also reduce of risk of encrypting data that cannot be decrypted. These features are not effective outside of AWS KMS. For details, see <a href=\"https://docs.aws.amazon.com/kms/latest/developerguide/download-public-key.html#download-public-key-considerations\">Special Considerations for Downloading Public Keys</a>.</p> <p>To help you use the public key safely outside of AWS KMS, <code>GetPublicKey</code> returns important information about the public key in the response, including:</p> <ul> <li> <p> <a href=\"https://docs.aws.amazon.com/kms/latest/APIReference/API_GetPublicKey.html#KMS-GetPublicKey-response-CustomerMasterKeySpec\">CustomerMasterKeySpec</a>: The type of key material in the public key, such as <code>RSA_4096</code> or <code>ECC_NIST_P521</code>.</p> </li> <li> <p> <a href=\"https://docs.aws.amazon.com/kms/latest/APIReference/API_GetPublicKey.html#KMS-GetPublicKey-response-KeyUsage\">KeyUsage</a>: Whether the key is used for encryption or signing.</p> </li> <li> <p> <a href=\"https://docs.aws.amazon.com/kms/latest/APIReference/API_GetPublicKey.html#KMS-GetPublicKey-response-EncryptionAlgorithms\">EncryptionAlgorithms</a> or <a href=\"https://docs.aws.amazon.com/kms/latest/APIReference/API_GetPublicKey.html#KMS-GetPublicKey-response-SigningAlgorithms\">SigningAlgorithms</a>: A list of the encryption algorithms or the signing algorithms for the key.</p> </li> </ul> <p>Although AWS KMS cannot enforce these restrictions on external operations, it is crucial that you use this information to prevent the public key from being used improperly.

This guide describes the AWS KMS operations that you can call programmatically. For general information about AWS KMS, see the <a href=\"https://docs.aws.amazon.com/kms/latest/developerguide/\"> <i>AWS Key Management Service Developer Guide</i> </a>.</p> <note> <p>AWS provides SDKs that consist of libraries and sample code for various programming languages and platforms (Java, Ruby, .Net, macOS, Android, etc.). The SDKs provide a convenient way to create programmatic access to AWS KMS and other AWS services. 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>.</p> </note> <p>We recommend that you use the AWS SDKs to make programmatic API calls to AWS KMS.</p> <p>Clients must support TLS (Transport Layer Security) 1.0. We recommend TLS 1.2. Clients must also support cipher suites with Perfect Forward Secrecy (PFS) such as Ephemeral Diffie-Hellman (DHE) or Elliptic Curve Ephemeral Diffie-Hellman (ECDHE). Most modern systems such as Java 7 and later support these modes.</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 <i>do not</i> use your AWS account (root) access key ID and secret key for everyday work with AWS KMS. Instead, use the access key ID and secret access key for an IAM user. You can also use the AWS Security Token Service to generate temporary security credentials that you can use to sign requests.</p> <p>All AWS KMS operations require <a href=\"https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html\">Signature Version 4</a>.</p> <p> <b>Logging API Requests</b> </p> <p>AWS KMS supports AWS CloudTrail, a service that logs 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 AWS 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=\"https://docs.aws.amazon.com/awscloudtrail/latest/userguide/\">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> <p> <a href=\"https://docs.aws.amazon.com/general/latest/gr/aws-security-credentials.html\">AWS Security Credentials</a> - This topic provides general information about the types of credentials used for accessing AWS.</p> </li> <li> <p> <a href=\"https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp.html\">Temporary Security Credentials</a> - This section of the <i>IAM User Guide</i> describes how to create and use temporary security credentials.</p> </li> <li> <p> <a href=\"https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html\">Signature Version 4 Signing Process</a> - This set of topics walks you through the process of signing a request using an access key ID and a secret access key.</p> </li> </ul> <p> <b>Commonly Used API Operations</b> </p> <p>Of the API operations discussed in this guide, the following will prove the most useful for most applications.
