To decrypt the encrypted data, you must use the same key that was used during encryption. The decrypted text that is returned from Cloud KMS is base64-encoded.\n\n[Cloud KMS](https://cloud.google.com/kms/docs) is a Google Cloud service that allows you to create, import, and manage cryptographic keys and perform cryptographic operations in a single centralized cloud service.\n\nBefore you begin\n----------------\n\nEnsure that you perform the following tasks in your Google Cloud project before configuring the **Cloud KMS - decrypt** task:\n\n1. Enable the Cloud Key Management Service (KMS) API (`cloudkms.googleapis.com`).\n\n\n [Enable the Cloud Key Management Service (KMS) API](https://console.cloud.google.com/flows/enableapi?apiid=cloudkms.googleapis.com)\n2. Create an [authentication profile](/application-integration/docs/configuring-auth-profile#createAuthProfile). Application Integration uses an authentication profile to connect to an authentication endpoint for the **Cloud KMS - decrypt** task. **Note:** If you're creating an authentication profile of [Service account](/application-integration/docs/configure-authentication-profiles#service-account) type, then ensure that the service account is assigned with the IAM role that contains the following IAM permission(s):\n | - `cloudkms.cryptoKeyVersions.useToDecrypt`\n |\n | To know about IAM permissions and the predefined IAM roles that grant them, see [IAM permissions reference](/iam/docs/permissions-reference#search).\n |\n | For information about granting additional roles or permissions to a service account, see [Granting, changing, and revoking access](/iam/docs/granting-changing-revoking-access).\n\nConfigure the Cloud KMS - decrypt task\n--------------------------------------\n\n1. In the Google Cloud console, go to the **Application Integration** page.\n\n [Go to Application Integration](https://console.cloud.google.com/integrations)\n2. In the navigation menu, click **Integrations** .\n\n\n The **Integrations** page appears listing all the integrations available in the Google Cloud project.\n3. Select an existing integration or click **Create integration** to create a new one.\n\n\n If you are creating a new integration:\n 1. Enter a name and description in the **Create Integration** pane.\n 2. Select a region for the integration. **Note:** The **Regions** dropdown only lists the regions provisioned in your Google Cloud project. To provision a new region, click **Enable Region** . See [Enable new region](/application-integration/docs/enable-new-region) for more information.\n 3. Select a service account for the integration. You can change or update the service account details of an integration any time from the info **Integration summary** pane in the integration toolbar. **Note:** The option to select a service account is displayed only if you have enabled integration governance for the selected region.\n 4. Click **Create** . The newly created integration opens in the *integration editor*.\n\n\n4. In the *integration editor* navigation bar, click **Tasks** to view the list of available tasks and connectors.\n5. Click and place the **Cloud KMS - decrypt** element in the integration editor.\n6. Click the **Cloud KMS - decrypt** element on the designer to view the **Cloud KMS - decrypt** task configuration pane.\n7. Go to **Authentication** , and select an existing authentication profile that you want to use.\n\n Optional. If you have not created an authentication profile prior to configuring the task, Click **+ New authentication profile** and follow the steps as mentioned in [Create a new authentication profile](/application-integration/docs/configuring-auth-profile#createAuthProfile).\n8. Go to **Task Input** , and configure the displayed inputs fields using the following [Task input parameters](#params) table.\n\n Changes to the inputs fields are saved automatically.\n\nTask input parameters\n---------------------\n\n\nThe following table describes the input parameters of the **Cloud KMS - decrypt** task:\n\nTask output\n-----------\n\nThe **Cloud KMS - decrypt** task returns a response containing the decrypted data in a base64-encoded format. You must decode the base64-encoded value to get the output string.\n| **Tip:** You can base64-encode or decode data using the **base64** command on Linux or macOS, or the **Base64.exe** command on Windows. Programming and scripting languages typically include libraries for base64-encoding. For command-line examples, see [Decode base64](/text-to-speech/docs/base64-decoding#linux) in the Cloud Text-to-Speech documentation.\n\n\u003cbr /\u003e\n\nError handling strategy\n-----------------------\n\n\nAn error handling strategy for a task specifies the action to take if the task fails due to a [temporary error](/application-integration/docs/error-handling). For information about how to use an error handling strategy, and to know about the different types of error handling strategies, see [Error handling strategies](/application-integration/docs/error-handling-strategy).\n\nWhat's next\n-----------\n\n1. Add [edges and edge conditions](/application-integration/docs/edge-overview).\n2. [Test and publish](/application-integration/docs/test-publish-integrations) your integration.\n3. Configure a [trigger](/application-integration/docs/how-to-guides#configure-triggers).\n4. Add a [Data Mapping task](/application-integration/docs/data-mapping-task).\n5. See [all tasks for Google Cloud services](/application-integration/docs/how-to-guides#configure-tasks-for-google-cloud-services)."]]
