AWS KMS - Apache Camel

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 KMS component supports 11 options, which are listed below.

Name	Description	Default	Type
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. 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. 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
basicPropertyBinding (advanced)	Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities	false	boolean

Usage

Message headers evaluated by the KMS producer

Header Type Description

Header	Type	Description
`CamelAwsKMSLimit`	`Integer`	The limit number of keys to return while performing a listKeys operation
`CamelAwsKMSOperation`	`String`	The operation we want to perform
`CamelAwsKMSDescription`	`String`	A key description to use while performing a createKey operation
`CamelAwsKMSKeyId`	`String`	The key Id

CamelAwsKMSLimit

Integer

The limit number of keys to return while performing a listKeys operation

CamelAwsKMSOperation

String

The operation we want to perform

CamelAwsKMSDescription

String

A key description to use while performing a createKey operation

CamelAwsKMSKeyId

String

KMS Producer operations

Camel-AWS KMS component provides the following operation on the producer side:

listKeys
createKey
disableKey
scheduleKeyDeletion
describeKey
enableKey

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 -->
