                    AWSKMSGrantConstraints

Use this structure to allow cryptographic operations in the grant only when the operation request includes the specified encryption context.

KMS applies the grant constraints only to cryptographic operations that support an encryption context, that is, all cryptographic operations with a symmetric KMS key. Grant constraints are not applied to operations that do not support an encryption context, such as cryptographic operations with asymmetric KMS keys and management operations, such as DescribeKey or RetireGrant.

In a cryptographic operation, the encryption context in the decryption operation must be an exact, case-sensitive match for the keys and values in the encryption context of the encryption operation. Only the order of the pairs can vary.

However, in a grant constraint, the key in each key-value pair is not case sensitive, but the value is case sensitive.

To avoid confusion, do not use multiple encryption context pairs that differ only by case. To require a fully case-sensitive encryption context, use the kms:EncryptionContext: and kms:EncryptionContextKeys conditions in an IAM or key policy. For details, see kms:EncryptionContext: in the Key Management Service Developer Guide.

                    AWSKMSXksKeyConfigurationType

Information about the external key that is associated with a KMS key in an external key store.

This element appears in a CreateKey or DescribeKey response only for a KMS key in an external key store.

The external key is a symmetric encryption key that is hosted by an external key manager outside of Amazon Web Services. When you use the KMS key in an external key store in a cryptographic operation, the cryptographic operation is performed in the external key manager using the specified external key. For more information, see External key in the Key Management Service Developer Guide.

Declaration

Objective-C

@interface AWSKMSXksKeyConfigurationType

Swift

class AWSKMSXksKeyConfigurationType


                    
                    
                    AWSKMSXksProxyAuthenticationCredentialType

KMS uses the authentication credential to sign requests that it sends to the external key store proxy (XKS proxy) on your behalf. You establish these credentials on your external key store proxy and report them to KMS.

The XksProxyAuthenticationCredential includes two required elements.

Required parameters: [AccessKeyId, RawSecretAccessKey]

Declaration

Objective-C

@interface AWSKMSXksProxyAuthenticationCredentialType

Swift

class AWSKMSXksProxyAuthenticationCredentialType


                    
                    
                    AWSKMSXksProxyConfigurationType

Detailed information about the external key store proxy (XKS proxy). Your external key store proxy translates KMS requests into a format that your external key manager can understand. These fields appear in a DescribeCustomKeyStores response only when the CustomKeyStoreType is EXTERNAL_KEY_STORE.

Key Management Service

Key Management Service (KMS) is an encryption and key management web service. This guide describes the KMS operations that you can call programmatically. For general information about KMS, see the Key Management Service Developer Guide.

KMS has replaced the term customer master key (CMK) with KMS key and KMS key. The concept has not changed. To prevent breaking changes, KMS is keeping some variations of this term.

Amazon Web Services 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 KMS and other Amazon Web Services 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 Amazon Web Services SDKs, including how to download and install them, see Tools for Amazon Web Services.

We recommend that you use the Amazon Web Services SDKs to make programmatic API calls to KMS.

If you need to use FIPS 140-2 validated cryptographic modules when communicating with Amazon Web Services, use the FIPS endpoint in your preferred Amazon Web Services Region. For more information about the available FIPS endpoints, see Service endpoints in the Key Management Service topic of the Amazon Web Services General Reference.

All KMS API calls must be signed and be transmitted using Transport Layer Security (TLS). KMS recommends you always use the latest supported TLS version. 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.

Signing Requests

Requests must be signed using an access key ID and a secret access key. We strongly recommend that you do not use your Amazon Web Services account root access key ID and secret access key for everyday work. You can use the access key ID and secret access key for an IAM user or you can use the Security Token Service (STS) to generate temporary security credentials and use those to sign requests.

All KMS requests must be signed with Signature Version 4.

Logging API Requests

KMS supports CloudTrail, a service that logs Amazon Web Services API calls and related events for your Amazon Web Services 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 CloudTrail User Guide.

Commonly Used API Operations

Of the API operations discussed in this guide, the following will prove the most useful for most applications. You will likely perform operations other than these, such as creating keys and assigning policies, by using the console.
