Jasypt

Jasypt component

Available as of Camel 2.5

Jasypt is a simplified encryption library which makes encryption and decryption easy. Camel integrates with Jasypt to allow sensitive information in Properties files to be encrypted. By dropping camel-jasypt on the classpath those encrypted values will automatic be decrypted on-the-fly by Camel. This ensures that human eyes can't easily spot sensitive information such as usernames and passwords.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-jasypt</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI Options

The options below are exclusive for the Jasypt component.

Protecting the master password

The master password used by Jasypt must be provided, so its capable of decrypting the values. However having this master password out in the opening may not be an ideal solution. Therefore you could for example provided it as a JVM system property or as a OS environment setting. If you decide to do so then the password option supports prefixes which dictates this. sysenv: means to lookup the OS system environment with the given key. sys: means to lookup a JVM system property.

For example you could provided the password before you start the application

$ export CAMEL_ENCRYPTION_PASSWORD=secret

Then start the application, such as running the start script.

When the application is up and running you can unset the environment

$ unset CAMEL_ENCRYPTION_PASSWORD

The password option is then a matter of defining as follows: password=sysenv:CAMEL_ENCRYPTION_PASSWORD.

Example with Java DSL

In Java DSL you need to configure Jasypt as a JasyptPropertiesParser instance and set it on the Properties component as show below:

The properties file myproperties.properties then contain the encrypted value, such as shown below. Notice how the password value is encrypted and the value has the tokens surrounding ENC(value here)

Example with Spring XML

In Spring XML you need to configure the JasyptPropertiesParser which is shown below. Then the Camel Properties component is told to use jasypt as the properties parser, which means Jasypt have its chance to decrypt values looked up in the properties.

The Properties component can also be inlined inside the <camelContext> tag which is shown below. Notice how we use the propertiesParserRef attribute to refer to Jasypt.
