h3. Shiro Security Basics

To employ Shiro security on a camel route, a ShiroSecurityPolicy object must be instantiated with security configuration details (including users, passwords, roles etc). This object must then be applied to a camel route. This ShiroSecurityPolicy Object may also be registered in the Camel registry (JNDI or ApplicationContextRegistry) and then utilized on other routes in the Camel Context.

Configuration details are provided to the ShiroSecurityPolicy using an Ini file (properties file) or an Ini object. The Ini file is a standard Shiro configuration file containing user/role details as shown

[users]
# user 'ringo' with password 'starr' and the 'sec-level1' role
ringo = starr, sec-level1
george = harrison, sec-level2
john = lennon, sec-level3
paul = mccartney, sec-level3

[roles]
# 'sec-level3' role has all permissions, indicated by the 
# wildcard '*'
sec-level3 = *

# The 'sec-level2' role can do anything with access of permission 
# readonly (*) to help
sec-level2 = zone1:*

# The 'sec-level1' role can do anything with access of permission 
# readonly   
sec-level1 = zone1:readonly:*

ShiroSecurityPolicy Options

Wiki Markup
{div:class=confluenceTableSmall}
|| Name || Default Value || Type || Description ||
| {{iniResourcePath or ini}} | {{none}} | Resource String or Ini Object | A mandatory Resource String for the iniResourcePath or an instance of an Ini object must be passed to the security policy. Resources can be acquired from the file system, classpath, or URLs when prefixed with "file:, classpath:, or url:" respectively. For e.g "classpath:shiro.ini" |
| {{passPhrase}} | {{An AES 128 based key}} | byte[] | A passPhrase to decrypt ShiroSecurityToken(s) sent along with Message Exchanges |
| {{alwaysReauthenticate}} | {{true}} | boolean | Setting to ensure re-authentication on every individual request. If set to false, the user is authenticated and locked such than only requests from the same user going forward are authenticated. |
| {{permissionsList}} | {{none}} | List<Permission> | A List of permissions required in order for an authenticated user to be authorized to perform further action i.e continue further on the route. If no Permissions list is provided to the ShiroSecurityPolicy object, then authorization is deemed as not required |
| {{cipherService}} | {{AES}} | org.apache.shiro.crypto.CipherService | Shiro ships with AES & Blowfish based CipherServices. You may use one these or pass in your own Cipher implementation |
| {{base64}} | {{false}} | {{boolean}} | *Camel 2.12:* To use base64 encoding for the security token header, which allows transferring the header over [JMS] etc. This option must also be set on {{ShiroSecurityTokenInjector}} as well. |

Sending Messages to routes secured by a ShiroSecurityPolicy

Messages and Message Exchanges sent along the camel route where the security policy is applied need to be accompanied by a SecurityToken in the Exchange Header. The SecurityToken is an encrypted object that holds a Username and Password. The SecurityToken is encrypted using AES 128 bit security by default and can be changed to any cipher of your choice.

Given below is an example of how a request may be sent using a ProducerTemplate in Camel along with a SecurityToken

Sending Messages to routes secured by a ShiroSecurityPolicy (much easier from Camel 2.12 onwards)

From Camel 2.12 onwards its even easier as you can provide the subject in two different ways.

Using ShiroSecurityToken

You can send a message to a Camel route with a header of key ShiroSecurityConstants.SHIRO_SECURITY_TOKEN

...

of

...

the

...

type

...

org.apache.camel.component.shiro.security.ShiroSecurityToken

...

that

...

contains

...

the

...

username

...

and

...

password.

...

For

...

example:

{
Code Block
}
        ShiroSecurityToken shiroSecurityToken = new ShiroSecurityToken("ringo", "starr");

        template.sendBodyAndHeader("direct:secureEndpoint", "Beatle Mania", ShiroSecurityConstants.SHIRO_SECURITY_TOKEN, shiroSecurityToken);
{code}

You

...

can

...

also

...

provide

...

the

...

username

...

and

...

password

...

in

...

two

...

different

...

headers

...

as

...

shown

...

below:

{
Code Block
}
        Map<String, Object> headers = new HashMap<String, Object>();
        headers.put(ShiroSecurityConstants.SHIRO_SECURITY_USERNAME, "ringo");
        headers.put(ShiroSecurityConstants.SHIRO_SECURITY_PASSWORD, "starr");
        template.sendBodyAndHeaders("direct:secureEndpoint", "Beatle Mania", headers);
{code}

When

you

use

the

and

...

password

...

headers,

...

then

...

the

...

ShiroSecurityPolicy

...

in

the

Camel

route

...

will

...

automatic

...

transform

...

those

...

into

...

a

...

single

...

header

...

with

...

key

...

ShiroSecurityConstants.SHIRO_SECURITY_TOKEN

...

with

the

...

Then

is

...

either

...

a

...

ShiroSecurityToken

...

instance,

...

of

...

a

...

base64

representation

...

as

a

(the

when
