Services

Currently the following services are available

  • Memory / Session service be.securit.trustbuilder.util.TimedBlockingHashMap

  • MemCached / Session service be.securit.trustbuilder.service.MemcachedService

  • DateService be.securit.trustbuilder.service.DateService

  • EncryptionService be.securit.trustbuilder.service.EncryptionService

  • StoreEncryptionService be.securit.trustbuilder.service.StoreEncryptionService

  • Radius Endpoint Service be.securit.trustbuilder.service.RadiusService

  • Ldap Endpoint Service be.securit.trustbuilder.service.LdapService

  • Domtai Service be.securit.trustbuilder.service.DomTai

  • AMQProducerService: be.securit.trustbuilder.service.AMQProducerService

  • AMQConsumerService: be.securit.trustbuilder.service.AMQConsumerService

Getting direct access to a service from within the workflow can be done via the following

CODE
tb.getService("urlStore"); 

Session Management

Basic Session management in Trustbuilder can be enabled by adding the following property in trustbuilder.properties in the TB_HOME folder. This will delegate the storage of the session attributes into the container session.

CODE
sessionService=true 

The sessions can be stored in third-party storage services too. For this, you should set the property to the id of the service handling the storing/retrieval. Currently 3 other backends are available: Database, Memcached and Redis (For configuration see the services section). But it's pretty trivial to write your own, provided that this service implements TrustBuilderCacheService.

In order to use the session service in the workflow 4 functions were created:

CODE
// Get a session variable by it's key
getSessionVariable(key)

// Set a session variable with a specific key/value pair
setSessionVariable(key,value)

// Set the timeout of a session in case of a servlet backed session
setSessionTimeoutInSec(sec)

// InvalidateSession Invalidate the session in case of a servlet backed session
invalidateSession()

For example an in-memory store.

CODE
<stb:Service stb:id="urlStore" stb:type="be.securit.trustbuilder.util.TimedBlockingHashMap" stb:singleton="true">
   <stb:property stb:name="ttl">30000</stb:property>
</stb:Service>
<stb:Service stb:id="objectStore" stb:type="be.securit.trustbuilder.util.TimedBlockingHashMap" stb:singleton="true">
  <stb:property stb:name="ttl">30000</stb:property>
</stb:Service>

In this example we configure 2 memory stores, this can be used to store a session, send information between threads and so on. The ttl property specifies how long a key exists in the store in milliseconds.

Encryption Service

Properties

keySpec password tool encoded key key raw base64 encoded key iv initialization vector for ciphers in feedback mode (encoded with password tool) encoding Sets the character encoding , default is UTF-8

Functions

function

Description

encrypt(cipher,string,format)

Encrypt the string and return the encrypted data in the format (base64,hex,y64)

decrypt(cipher,encryptedString,format)

Decrypt the encryptedString by decoding in format (base64,hex,y64) and return the original string

sign(algorithm,data,decodingFormat,encodingFormat)

Sign the data decoded with decodingFormat and return the signature in the encodingFormat (base64,hex,y64)

verify(algorithm,data,signature,decodingFormat)

Verify the data by decoding in decodingFormat (base64,hex,y64)

generateHMac(cipher,string,inputformat, outputformat)

Encrypt the string with hmac and return the result in the outputformat (base64,hex, y64).
Inputformat : null, base64, hex, y64

hash(hashAlg, message, encodingFormat)

Hash (according to the hashAlg=algorithm) the message and return it in the encoding format (base64, hex, y64)

saltedHash(password, salt)

Hashes (sha-1) the concatenated password+salt and retuns it base64 encoded

generateSalt(int len)

Generates a salt with the specified length

Available ciphers can be found for the sun at jdk6 jdk7

Example

CODE
var encryptionService = tb.getService("encryption"); // encryption is the name of the service
var pwd_hash_user = encryptionService.hash("SHA-512",workItem.input.credentials.password+salt,"base64");

// Encrypts the signaturebase with HMAC-SHA1 and returns a BASE64 encoded string
var signature = encryptionService.generateHMac( "HmacSHA1", signaturebase, null, "base64");

.setKey

When using the setKey functionality it's recommended to use the Encryption Service with the singleton flag set to false. If the singleton is set to true, the key is persistent until the next .setKey call or restart of the TrustBuilder Server.

Some cases another key must be used instead of the default one. This key can be set dynamic as an BASE64 encoded string.

CODE
encryptionService.setKey(tb.base64Encode("5VRtmBeg9jRJ5mRAsncaGwCGJ2YazTxReQIqbcHqZc",true));   // Encode as string true
var signature = encryptionService.generateHMac( "HmacSHA1", signaturebase, "base64");   // base64 is default

LDAP Endpoint Service

classname : be.securit.trustbuilder.service.LdapService

The LDAP endpoint service is opening a listener port for the ldap endpoint.

Currently only a search and authenticate is supported. Search is however limited to what you define in the workflows. Using a normal ldap client to browse the server isn't possible as the endpoint is ment for authentication only.

Properties
  • port : Port used for the listener

  • workflow : Which workflow has to be run by the engine when this service is called

Note on ldap port

If you running your as non-root user you can't open ports under 1024. We recommend setting the ldap port higher and if you want to use port 389 fpr ldap make usage of software that forwards the connection from port 389 to your trustbuilder ldap endpoint.

Config
CODE
<stb:Service stb:id="ldapserv" stb:singleton="false" stb:synchronised="false" stb:type="be.securit.trustbuilder.service.LdapService">
   <stb:property stb:name="port">1389</stb:property>
   <stb:property stb:name="workflow">ldapworkflow</stb:property>
</stb:Service>

We set the listener to port 1389 and attach the "ldapworkflow" to it. Each requests to this endpoint starts the configured workflow.

Requests

Bind Request

CODE
{"user":"null","type":"bind","ip":"10.0.10.243","dn":"cn=administrator,dc=securit,dc=biz","password":"somepasswd"} 

Exposed fields in the input :

CODE
user : 
type : bind 
ip : ip of requesting host 
dn : DN to bind to 
password : the given password to bind

Search Request

CODE
Engine.WorkItem - set ___INPUT___=LdapEndpointSearchRequest: {
       baseDN: 'dc=securit,dc=biz',
       scope: 'SUB',
       filter: '(&(objectclass=posixaccount)(uid=ewold))',
       attributes: '[userPassword, cn, gidNumber, uidNumber, loginShell, objectClass, gecos, uid, homeDirectory]',
} []

{"user":"null","type":"search","base":"dc=securit,dc=biz","scope":"SUB","filter":"(&(objectclass=posixaccount)(uid=username))","attributes":["userPassword","cn","gidNumber","uidNumber","loginShell","objectClass","gecos","uid","homeDirectory"]}

Exposed fields in input :

CODE
User : 
Type : Search 
Base : Search base 
Scope : Search scope 
Filter : Search filter 
Attributs : Required attributes in return

Response

To create a response to the ldap client TrustBuilder uses a function that called on the input object.

Bind Response :

CODE
// Authentication accepted
workItem.output = workItem.input.generateResponse(0);

// Authentication rejected
workItem.output = workItem.input.generateResponse(49);

Search Response :

CODE
var username = "testuser";
var response = {
                       "host" : "10.0.10.243",
                       "gidNumber" : info.gidNumber,
                       "uidNumber" : info.uidNumber,
                       "homeDirectory" : info.homeDirectory,
                       "loginShell" : info.loginShell,
                       "userPassword" : "password"
               };
workItem.output = workItem.input.generateResponse(0);
// Add search Result and attributes
workItem.output.addResult("cn="+username,response);

The addResult function can be called multiple times.

Returning error codes

The 49 is an invalid credentials error code. If you wish to use other codes you can have a look at : http://docs.oracle.com/javase/jndi/tutorial/ldap/models/exceptions.html
