AWS Key Management Service FAQs
Please visit this FAQ link for content relevant to these two China regions. General Q: AWS KMS provides a highly available key storage, management, and auditing solution for you to encrypt data within your own applications and control the encryption of stored data across AWS services. If you want full control over the management of your keys, including the ability to share access to keys across accounts or services, you can create your own master keys in KMS.
You can also use the master keys that you create in KMS directly within your own applications. Visit the Getting Started page to learn more. In what Regions is KMS available? Availability is listed on our global Products and Services by Region page.
These are known as customer master keys or CMKs. These master keys are protected by hardware security modules HSMs and are only ever used within those modules. You can submit data directly to KMS to be encrypted or decrypted using these master keys.
You set usage policies on these keys that determine which users can use them to encrypt and decrypt data under which conditions. Under this method, KMS generates data keys which are used to encrypt data and are themselves encrypted using your master keys in KMS. Data keys are not retained or managed by KMS. AWS services encrypt your data and store an encrypted copy of the data key along with the data it protects. When a service needs to decrypt your data they request KMS to decrypt the data key using your master key.
If the user requesting data from the AWS service is authorized to decrypt under your master key policy, the service will receive the decrypted data key from KMS with which it can decrypt the your data and return it in plaintext.
All requests to use your master keys are logged in AWS CloudTrail so you can understand who used which key under which context and when they used it. In this case data is encrypted using data keys that are protected by your master keys in KMS.
In some cases data is encrypted by default using keys that are stored in KMS but owned and managed by the AWS service in question. In many cases the master keys are owned and managed by you within your account. Some services give you the choice of managing the keys yourself or allowing the service to manage the keys on your behalf. Why use envelope encryption? Envelope encryption reduces the network load since only the request and delivery of the much smaller data key go over the network.
The data key is used locally in your application or encrypting AWS service, avoiding the need to send the entire block of data to KMS and suffer network latency. You have the option of selecting a specific customer master key CMK to use when you want an AWS service to encrypt data on your behalf.
These are known as customer managed CMKs and you have full control over them. You define the access control and usage policy for each key and you can grant permissions to other accounts and services to use them. Why should I create my own customer master keys? You can define an alias and description for the key and opt-in to have the key automatically rotated once per year if it was generated by AWS KMS.
You also define all the permissions on the key to control who can use or manage the key. You can import a copy of your key from your own key management infrastructure to AWS KMS and use it with any integrated AWS service or from within your own applications.
When would I use an imported key? You can use an imported key to get greater control over the creation, lifecycle management, and durability of your key in AWS KMS. Imported keys are designed to help you meet your compliance requirements which may include the ability to generate or maintain a secure copy of the key in your infrastructure, and the ability to immediately delete the imported copy of the key from AWS infrastructure.
What type of keys can I import? You can import bit symmetric keys. There are two main differences: You are responsible for maintaining a copy of your imported keys in your key management infrastructure so that you can re-import them at any time. You may set an expiration period for an imported key. You may also delete imported key material on demand. In both cases the key material itself is deleted but the CMK reference in KMS and associated metadata are retained so that the key material can be re-imported in the future.
Keys generated by AWS KMS do not have an expiration time and cannot be deleted immediately; there is a mandatory 7 to 30 day wait period. All customer managed CMKs, irrespective of whether the key material was imported, can be manually disabled or scheduled for deletion. In this case the CMK itself is deleted, not just the underlying key material. Can I rotate my keys?
If you choose to import keys to AWS KMS or use a custom key store, you can manually rotate them whenever you want by creating a new CMK and mapping a key alias from the old key to the new key.
AWS KMS automatically keeps previous versions of keys to use for decryption of data encrypted under an old version of a key. If you manually rotate your imported or custom key store keys, you may have to re-encrypt your data depending on whether you decide to keep old versions of keys available.
You can schedule a customer master key and associated metadata that you created in AWS KMS for deletion, with a configurable waiting period from 7 to 30 days. This waiting period allows you to verify the impact of deleting a key on your applications and users that depend on it.
The default waiting period is 30 days. You can cancel key deletion during the waiting period. The key cannot be used if it is scheduled for deletion until you cancel the deletion during the waiting period.
Once a key is deleted, you can no longer use it. All data protected under a deleted master key is inaccessible. For customer master keys with imported key material, you can delete the key material without deleting the customer master key id or metadata in two ways. First, you can delete your imported key material on demand without a waiting period. Second, at the time of importing the key material into the customer master key, you may define an expiration time for how long AWS can use your imported key material before it is deleted.
You can re-import your key material into the customer master key if you need to use it again. What should I do if my imported key material has expired or I accidentally deleted it? You can re-import your copy of the key material with a valid expiration period to AWS KMS under the original customer master key so it can be used. Can I be alerted that I need to re-import the key? Once you import your key to a customer master key, you will receive an Amazon CloudWatch Metric every few minutes that counts down the time to expiration of the imported key.
You will also receive an Amazon CloudWatch Event once the imported key under your customer master key expires. You can build logic that acts on these metrics or events and automatically re-imports the key with a new expiration period to avoid an availability risk. You can create up to customer master keys per account per region.
As both enabled and disabled customer master keys count towards the limit, we recommend deleting disabled keys that you no longer use. AWS managed master keys created on your behalf for use within supported AWS services do not count against this limit. There is no limit to the number of data keys that can be derived using a master key and used in your application or by AWS services to encrypt data on your behalf.
Custom Key Store Q: What is a custom key store? Additional guidance for deciding if using a custom key store it is right for you can be found in this blog. Why would I need to use a custom key store? There are four reasons why you might find a custom key store useful. Firstly, you might have keys that are explicitly required to be protected in a single tenant HSM or in an HSM over which you have direct control.
Secondly, you might have keys that are required to be stored in an HSM that has been validated to FIPS level 3 overall the HSMs used in the standard KMS key store are either validated or in the process of being validated to level 2 with level 3 in multiple categories. Thirdly, you might need the ability to immediately remove key material from KMS and to prove you have done so by independent means. Do custom key stores affect how keys are managed? You cannot import key material into your custom key store and you cannot have KMS automatically rotate keys.
In all other respects, including the type of keys that can be generated, the way that keys use aliases and how policies are defined, keys that are stored in a custom key store are managed in the same way as any other KMS customer managed CMK. Can I use a custom key store to store an AWS managed customer master key? Do custom key stores affect how keys are used?
Authentication and authorization processes operate independently of where the key is stored. However, the actual cryptographic operations happen exclusively in either the custom key store or the default KMS key store. How can I audit the use of keys in a custom key store?
Second, each cluster also captures its own local logs to record user and key management activity. What impact does using a custom key store have on availability of keys? The number of HSMs you use and your choice of availability zones AZs can also affect the resilience of your cluster.
As in any key management system, it is important to understand how the availability of keys can impact the recovery of your encrypted data. What are the performance limitations associated with a custom key store? What are the costs associated with using a custom key store? There are no additional charges for using a custom key store. What additional skills and resources are required to configure a custom key stores?
These are security sensitive tasks and you should ensure that you have the appropriate resources and organizational controls in place. Can I import keys into a custom key store? Can I migrate keys between the default KMS keys store and a custom key store? All keys must be created in the key store in which they will be used, except in situations where you import you own key material into the default KMS key store.
Can I rotate keys stored in a custom key store?
