  3. What Is Aws Kms
  4. Aws Key Management Service Kms

The examples in this topic use the Encrypt, Decrypt, and ReEncrypt operations in the AWS KMS API. These operations are designed to encrypt and decrypt data keys.They use an AWS KMS customer master key (CMK) in the encryption operations and they cannot accept more than 4 KB (4096 bytes) of data. This document assumes you've already set up an Amazon Web Services (AWS) account, created a master key in the Key Management Service (KMS), and have done the basic work to se. You can request that AWS KMS generate data keys and return them for use in your own application. The data keys are encrypted under a master key you define in AWS KMS so that you can safely store the encrypted data key along with your encrypted data. The above command works; however, I do have a question, I was trying to use AWS CLI to generate a data key, how do I save ciphertextblob as binary so that decrypt command can decrypt plain text data key. Or there is a way to specify -ciphertext-blob as base64 encoded file?

Easily create and control the keys used to encrypt or digitally sign your data

AWS Key Management Service (KMS) makes it easy for you to create and manage cryptographic keys and control their use across a wide range of AWS services and in your applications. AWS KMS is a secure and resilient service that uses hardware security modules that have been validated under FIPS 140-2, or are in the process of being validated, to protect your keys. AWS KMS is integrated with AWS CloudTrail to provide you with logs of all key usage to help meet your regulatory and compliance needs.

Try AWS Key Management Service

AWS Free Tier includes 20,000 free AWS Key Management Service requests each month.


Fully managed

You control access to your encrypted data by defining permissions to use keys while AWS KMS enforces your permissions and handles the durability and physical security of your keys.

Centralized key management

AWS KMS presents a single control point to manage keys and define policies consistently across integrated AWS services and your own applications. You can easily create, import, rotate, delete, and manage permissions on keys from the AWS Management Console or by using the AWS SDK or CLI.

Manage encryption for AWS services

AWS KMS is integrated with AWS services to simplify using your keys to encrypt data across your AWS workloads. You choose the level of access control that you need, including the ability to share encrypted resources between accounts and services. KMS logs all use of keys to AWS CloudTrail to give you an independent view of who accessed your encrypted data, including AWS services using them on your behalf.

Encrypt data in your applications

AWS KMS is integrated with the AWS Encryption SDK to enable you to used KMS-protected data encryption keys to encrypt locally within your applications. Using simple APIs you can also build encryption and key management into your own applications wherever they run.

Digitally sign data

AWS KMS enables you to perform digital signing operations using asymmetric key pairs to ensure the integrity of your data. Recipients of digitally signed data can verify the signatures whether they have an AWS account or not.

Low cost

There is no commitment and no upfront charges to use AWS KMS. You only pay US $1/month to store any key that you create. AWS managed keys that are created on your behalf by AWS services are free to store. You are charged per-request when you use or manage your keys beyond the free tier.

AWS KMS uses hardware security modules (HSMs) that have been validated under FIPS 140-2, or are in the process of being validated, to generate and protect keys. Your keys are only used inside these devices and can never leave them unencrypted. KMS keys are never shared outside the AWS region in which they were created.

The security and quality controls in AWS KMS have been certified under multiple compliance schemes to simplify your own compliance obligations. AWS KMS provides the option to store your keys in single-tenant HSMs in AWS CloudHSM instances that you control.

Built-in auditing

AWS KMS is integrated with AWS CloudTrail to record all API requests, including key management actions and usage of your keys. Logging API requests helps you manage risk, meet compliance requirements and conduct forensic analysis.

Activate Windows using a Systems Manager Automation document

The AWSSupport-ActivateWindowsWithAmazonLicense Automation document activates an Amazon EC2 Windows instance with a license provided by Amazon. The automation checks the current status of Windows for your instance, and then activates Windows if the status is inactive.

Note: This solution can't be used with Bring Your Own License (BYOL) Windows instances. To use your own license, see Microsoft Licensing on AWS.

1. Open the AWS Systems Manager console. Be sure to select the same Region as the EC2 Windows instance that requires Windows activation.

2. Choose Automation from the navigation pane, and then choose Execute automation.

3. In the search field, enter AWSSupport-ActivateWindowsWithAmazonLicense. Select the Automation document, and then choose Next.

4. For Execute automation document, choose Simple execution.

5. For Input parameters, turn on Show interactive instance picker.

6. Choose your EC2 instance.

Note: If you don't see your instance in the list, the instance isn't enabled for Systems Manager. Review the prerequisites for using Systems Manager to manage your Amazon EC2 instances.

If you don't want to enable Systems Manager, or if the instance is not available in Input parameters, turn off Show interactive instance picker. For InstanceID, enter the ID for your impaired instance. For AllowOffline, choose True.

Important: If you set AllowOffline to True, your instance will stop and restart. Data in instance store volumes will be lost. The public IP address changes if you aren’t using an Elastic IP address.

7. Choose Execute.

8. To monitor the execution progress, open the Systems Manger console, and then choose Automation from the navigation pane. Choose the running automation, and then review the Executed steps. To view the automation output, expand Outputs.

Activate Windows manually

1. Update EC2Config, or run the EC2Launch initialization script.

For Windows Server 2012 R2 and earlier: Update EC2Config, and then restart the instance.
