== Camel-SSH using Key Example

=== Introduction

This examples shows how to use the Camel-SSH component to call Apache
Karaf using Public Key versus password. It can be run using Maven.

=== Requirements

* http://maven.apache.org[Apache Maven] version 3.x
* http://karaf.apache.org[Apache Karaf] version 2.3.1

=== Setup Karaf

We will need to make 2 changes to Karaf for this example to work.

[arabic]
. Register the Bouncy Castle Java Cryptography Extension (JCE) with
Karaf.
. Add a user and public key to Karaf’s identity store.

==== Register Bouncy Castle

We need the Bouncy Castle JCE as Karaf’s included Mina SSHD server uses
this to handle Public Key files.

Install the following jars into the `+<karaf_home>/lib/ext+` directory.

....
curl -O http://downloads.bouncycastle.org/java/bcprov-jdk15on-147.jar
curl -O http://downloads.bouncycastle.org/java/bcprov-ext-jdk15on-147.jar
curl -O http://downloads.bouncycastle.org/java/bcpkix-jdk15on-147.jar
....

Edit the `+<karaf_home>/etc/config.properties+` file, making 2 changes

[arabic]
. add the following line
+
org.apache.karaf.security.providers =
org.bouncycastle.jce.provider.BouncyCastleProvider
. update the `+org.osgi.framework.bootdelegation+` property, appending
`+,org.bouncycastle.*+` to the end. It should look something like the
following when done
+
org.osgi.framework.bootdelegation=org.apache.karaf.jaas.boot,sun._,com.sun._,javax.transaction,javax.transaction._,org.bouncycastle._

==== Add a user and public key

Edit the `+<karaf_home>/etc/keys.properties+` file, appending a new user
`+scott+`. The format of the keys.properties file is as follows

....
<user name>=<public key>,<role>
....

For this example you will need to add a new user `+scott+` with the key
value from the included `+src/main/resources/test_rsa.pub+` file. The
included Camel route uses the associated private key
`+src/main/resources/test_rsa+` when connecting to the updated Karaf
server.

Append the following to the `+<karaf_home>/etc/keys.properties+` file

....
scott=AAAAB3NzaC1yc2EAAAADAQABAAABAQC4MSqXneGVM9n3Rnqfya0D31crTx+J8X8dKZ5/+2Rq96/klnmt6uGyl+DI8G0HXVK66KqU2Z0qUE9ytOMR+zSPA+zU4Bhd3G82qdJsys7Nz8t9wSWQs8/ItWTjwg+b3vVLcI1Q8sSgfxqZvD/XQk4srbDs9ba55yjEPn5DOhA7UFbFAv8menSgbpNFMrUQQ9DJcMVlu3MOcMylI5UFFf1uvDD3vUoFXZa6GQOK9j1AGvfagGgBEqV4/AiKzDmQDFqMzmTfTfBpi1crY0SGXdT26PE4Knx7KP7bBJupBm6lJ9Pk39iw8dnDWcq45EEqrHsI0dps7/iQgYxYqBmFLIkP,_g_:admingroup
....

=== Build

To build, run the following command

....
mvn clean install
....

=== Run with maven

To test locally, assuming you have Setup Karaf and have it running, run
the following command

....
mvn camel:run
....

To stop the example hit ctrl+c

=== Run with Karaf

Karaf should be all configured at this point so start up an instance by
running the `+bin/karaf+` from the `+<karaf_home>+` directory.

....
karaf
....

From the running Karaf console, run the following commands to install
this example into your running Karaf server.

....
feature:repo-add mvn:org.apache.camel.example/camel-example-ssh-security/${version}/xml/features
feature:install camel-example-ssh-security
....

This example outputs into the Karaf log file so you can either
`+tail -f <karaf_home>data/log/karaf.log+` or from the Karaf console run
the following command

....
log:tail
....
