PutKeyPolicyRequest Class | AWS SDK for .NET V3

Container for the parameters to the PutKeyPolicy operation. Attaches a key policy to the specified KMS key.

For more information about key policies, see Key Policies in the Key Management Service Developer Guide. For help writing and formatting a JSON policy document, see the IAM JSON Policy Reference in the Identity and Access Management User Guide. For examples of adding a key policy in multiple programming languages, see Setting a key policy in the Key Management Service Developer Guide.

Cross-account use: No. You cannot perform this operation on a KMS key in a different Amazon Web Services account.

Required permissions: kms:PutKeyPolicy (key policy)

Related operations: GetKeyPolicy

Eventual consistency: The KMS API follows an eventual consistency model. For more information, see KMS eventual consistency.

The PutKeyPolicyRequest type exposes the following members

Constructors

	Name	Description
	PutKeyPolicyRequest()

Properties

Name	Type	Description
BypassPolicyLockoutSafetyCheck	System.Boolean	Gets and sets the property BypassPolicyLockoutSafetyCheck. Skips ("bypasses") the key policy lockout safety check. The default value is false. Setting this value to true increases the risk that the KMS key becomes unmanageable. Do not set this value to true indiscriminately. For more information, see Default key policy in the Key Management Service Developer Guide. Use this parameter only when you intend to prevent the principal that is making the request from making a subsequent PutKeyPolicy request on the KMS key.
KeyId	System.String	Gets and sets the property KeyId. Sets the key policy on the specified KMS key. Specify the key ID or key ARN of the KMS key. For example: Key ID: `1234abcd-12ab-34cd-56ef-1234567890ab` Key ARN: `arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab` To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.
Policy	System.String	Gets and sets the property Policy. The key policy to attach to the KMS key. The key policy must meet the following criteria: The key policy must allow the calling principal to make a subsequent `PutKeyPolicy` request on the KMS key. This reduces the risk that the KMS key becomes unmanageable. For more information, see Default key policy in the Key Management Service Developer Guide. (To omit this condition, set `BypassPolicyLockoutSafetyCheck` to true.) Each statement in the key policy must contain one or more principals. The principals in the key policy must exist and be visible to KMS. When you create a new Amazon Web Services principal, you might need to enforce a delay before including the new principal in a key policy because the new principal might not be immediately visible to KMS. For more information, see Changes that I make are not always immediately visible in the Amazon Web Services Identity and Access Management User Guide. A key policy document can include only the following characters: Printable ASCII characters from the space character (`\u0020`) through the end of the ASCII character range. Printable characters in the Basic Latin and Latin-1 Supplement character set (through `\u00FF`). The tab (`\u0009`), line feed (`\u000A`), and carriage return (`\u000D`) special characters For information about key policies, see Key policies in KMS in the Key Management Service Developer Guide.For help writing and formatting a JSON policy document, see the IAM JSON Policy Reference in the Identity and Access Management User Guide.
PolicyName	System.String	Gets and sets the property PolicyName. The name of the key policy. If no policy name is specified, the default value is `default`. The only valid value is `default`.

Examples

The following example attaches a key policy to the specified KMS key.
