AWS Key Management Service (KMS)
Since Camel 2.21
Only producer is supported
The KMS component supports the ability to work with keys stored in AWS KMS instances.
Prerequisites
You must have a valid Amazon Web Services developer account, and be signed up to use Amazon KMS. More information is available at Amazon KMS.
URI Format
aws-kms://label[?options]
You can append query options to the URI in the following format, ?options=value&option2=value&…
URI Options
The AWS Key Management Service (KMS) component supports 12 options, which are listed below.
Name | Description | Default | Type |
---|---|---|---|
autoDiscoverClient (common) |
Setting the autoDiscoverClient mechanism, if true, the component will look for a client instance in the registry automatically otherwise it will skip that checking. |
true |
boolean |
accessKey (producer) |
Amazon AWS Access Key |
String |
|
configuration (producer) |
The Component configuration |
KMSConfiguration |
|
kmsClient (producer) |
To use a existing configured AWS KMS as client |
AWSKMS |
|
lazyStartProducer (producer) |
Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. |
false |
boolean |
operation (producer) |
Required The operation to perform. There are 6 enums and the value can be one of: listKeys, createKey, disableKey, scheduleKeyDeletion, describeKey, enableKey |
KMSOperations |
|
proxyHost (producer) |
To define a proxy host when instantiating the KMS client |
String |
|
proxyPort (producer) |
To define a proxy port when instantiating the KMS client |
Integer |
|
proxyProtocol (producer) |
To define a proxy protocol when instantiating the KMS client. There are 2 enums and the value can be one of: HTTP, HTTPS |
HTTPS |
Protocol |
region (producer) |
The region in which KMS client needs to work. When using this parameter, the configuration will expect the capitalized name of the region (for example AP_EAST_1) You’ll need to use the name Regions.EU_WEST_1.name() |
String |
|
secretKey (producer) |
Amazon AWS Secret Key |
String |
|
autowiredEnabled (advanced) |
Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc. |
true |
boolean |
The AWS Key Management Service (KMS) endpoint is configured using URI syntax:
aws-kms:label
with the following path and query parameters:

String |
|
secretKey (producer) |
Amazon AWS Secret Key |
String |
|
synchronous (advanced) |
Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). |
false |
boolean |
Required KMS component options
You have to provide the amazonKmsClient in the Registry or your accessKey and secretKey to access the Amazon KMS service.
Usage
Message headers evaluated by the KMS producer
Header | Type | Description |
---|---|---|
|
|
The limit number of keys to return while performing a listKeys operation |
|
|
The operation we want to perform |
|
|
A key description to use while performing a createKey operation |
|
|
The key Id |
Producer Examples
-
listKeys: this operation will list the available keys in KMS
from("direct:listKeys")
.to("aws-kms://test?kmsClient=#amazonKmsClient&operation=listKeys")
Automatic detection of AWSKMS client in registry
The component is capable of detecting the presence of an AWSKMS bean into the registry. If it’s the only instance of that type it will be used as client and you won’t have to define it as uri parameter. This may be really useful for smarter configuration of the endpoint.
Dependencies
Maven users will need to add the following dependency to their pom.xml.
pom.xml
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-aws-kms</artifactId>
<version>${camel-version}</version>
</dependency>
where ${camel-version}
must be replaced by the actual version of Camel.
Spring Boot Auto-Configuration
When using aws-kms with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:
<dependency>
<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-aws-kms-starter</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>
