Encrypt/Decrypt Endpoints not working for Symmetric Key

I have setup a simple project using Spring Cloud Config Server and I’m trying to simply encrypt and decrypt some values. I create the project as a Spring Starter Project using the following pom.xml with Spring Boot.

            </plugin>
        </plugins>
    </build>
</project>

From there I modify the main Spring Boot Application class to add the @EnableConfigServer annotation as follows:

@SpringBootApplication
@EnableConfigServer
public class SpringMicroservicesConfigServer6Application {

    public static void main(String[] args) {
        SpringApplication.run(SpringMicroservicesConfigServer6Application.class, args);
    }
}

Within my application.properties file, I point to a git repository, setup the server port and enable symmetric key encryption using encrypt.key as follows:

server.port=8888
spring.cloud.config.server.git.uri=C:/Users/training/Desktop/sts-workspace/configuration
encrypt.key=secret

Next I open a bash shell and encrypt some data:

$ curl http://localhost:8888/encrypt -d Kevin

Which produces the value:

315ca5592635e4f65e0a0278cd08f74b5cef27e8379bd0e0d81d08c9ed8fbac161d

If I attempt to decrypt the value using:

curl localhost:8888/decrypt --data-urlencode 315ca5592635e4f65e0a0278cd08f74b5cef27e8379bd0e0d81d08c9ed8fbac161d

I receive the following error:

276{"description":"Text not encrypted with this key","status":"INVALID"}

I do not understand why this simple example does not work. I have confirmed my JCE extension is in place using some simple code to test the .jar files are in place. Is this an issue or am I missing something?

I won’t shame you, happens all the time. How about a good LOL 😆 and we call it good.

Apologies if I sounded rude. Have submitted the PR.
