OpenStack Barbican & HSM Flow

December 28, 2016 Leave a comment

I assume you know what Hardware Security Module in short HSM is… if not

HSM Limitations

  • Maximum 20 partitions/slots (eg: Luna HSM)
    • Enough space to hold an RSA key-pair
    • Default total storage space on the HSM is 2 MB (upgrade to 15MB)
  • Only limited number of keys can be stored
  • Performance subject to network latency, scale and HSM performance

Barbican is an Openstack module for storing secrets. I’ll write few blog posts on Barbican PoC later. Barbican + HSM can make a great combination for storing your cloud secrets to meet security and PCI based compliance requirements. Not wasting time, here is how integration flow looks like…


High-Level flow of Barbican & HSM integration

  • MKEK (Master Key Encryption Key) is global key to Barbican
  • Project level unique KEK stored in Barbican (in fact encrypted KEK is stored)
  • Data Encryption Keys (DEK) stored in Barbican (in fact encrypted DEK is stored)
  • MKEK wraps every project’s unique KEK
  • KEK wraps project’s DEK


Tomcat 2 way SSL Configuration (Step-by-Step)

August 9, 2016 1 comment

The is a working POC for 2 way SSL configuration in Tomcat server, where client and server has OpenSSL key pairs. This POC covers CA, Server & Client all running on same machine.

Step 1: Create your own root CA

~/openssl$ mkdir -m 0700 /home/ubuntu/openssl/CA /home/ubuntu/openssl/CA/certs /home/ubuntu/openssl/CA/crl /home/ubuntu/openssl/CA/newcerts /home/ubuntu/openssl/CA/private

~/openssl$ touch /home/ubuntu/openssl/CA/indext.txt

~/openssl$ echo 1000 >> /home/ubuntu/openssl/CA/serial

~/openssl$ mv karun-tomcat-root-ca.key CA/private/

~/openssl$ sudo vi /etc/openssl.cnf
 # Make changes here
 dir = /home/ubuntu/openssl/CA
 #optionally change policy definitions as well

~/openssl$ openssl genrsa -des3 -out karun-tomcat-root-ca.key 2048
#In below command make sure to use CN=<hostname of your machine>

~/openssl$ openssl req -new -x509 -days 36520 -key karun-tomcat-root-ca.key -out karun-tomcat-root-ca.crt -config openssl.cnf

~$ sudo cp ~/openssl/CA/certs/karun-tomcat-root-ca.crt /usr/share/ca-certificates/

# make sure in the UI you enable/select the certificate created above

~$ sudo dpkg-reconfigure ca-certificates

# Now reboot ubuntu machine just to make sure certificates are loaded successfully and tomcat picks it


Step 2: Create Tomcat Server’s Key Pair

~$ openssl genrsa -out tomcat-server.key 2048

# Use common name =<Give IP address>, department = Tomcat Server CSR

~$ openssl req -new -sha256 -config ~/openssl/openssl.cnf -key tomcat-server.key -out tomcat-server.csr

~$ openssl x509 -req -sha256 -days 36520 -in tomcat-server.csr -signkey tomcat-server.key -CA ~/openssl/CA/certs/karun-tomcat-root-ca.crt -CAkey ~/openssl/CA/private/karun-tomcat-root-ca.key -CAcreateserial -out tomcat-server.crt

~$ openssl pkcs12 -export -name karun-tomcat-server-cert -in tomcat-server.crt -out tomcat-server.p12 -inkey tomcat-server.key -CAfile ~/openssl/CA/certs/karun-tomcat-root-ca.crt -caname karun-root -chain

~$ keytool -importkeystore -destkeystore tomcat-server.jks -srckeystore tomcat-server.p12 -srcstoretype pkcs12 -alias karun-tomcat-server-cert

~$ keytool -import -alias karun-root -keystore tomcat-server.jks -trustcacerts -file ~/openssl/CA/certs/karun-tomcat-root-ca.crt

# Run this once client cert is generated
~$ keytool -importkeystore -alias karun-tomcat-client-cert -srckeystore ~/client-certs/tomcat-client.p12 -srcstoretype PKCS12 -destkeystore tomcat-server.jks -deststoretype JKS

# Run this once tomcat server started successfully
~$ openssl s_client -connect localhost:8443 -cert ~/client-certs/tomcat-client.crt -key ~/client-certs/tomcat-client.key -debug -showcerts 

Step 3: Create Client Side Key Pair

~$ openssl genrsa -out tomcat-client.key 2048
# Use common name = <tomcat-user.xml's user say 'admin'>, department = Tomcat Client CSR

~$ openssl req -new -sha256 -config ~/openssl/openssl.cnf -key tomcat-client.key -out tomcat-client.csr

~$ openssl x509 -req -sha256 -days 36520 -in tomcat-client.csr -signkey tomcat-client.key -CA ~/openssl/CA/certs/karun-tomcat-root-ca.crt -CAkey ~/openssl/CA/private/karun-tomcat-root-ca.key -CAcreateserial -out tomcat-client.crt

~$ openssl pkcs12 -export -name karun-tomcat-client-cert -in tomcat-client.crt -out tomcat-client.p12 -inkey tomcat-client.key -CAfile ~/openssl/CA/certs/karun-tomcat-root-ca.crt -caname karun-root -chain

~$ (optional step) keytool -importkeystore -destkeystore tomcat-client.jks -srckeystore tomcat-client.p12 -srcstoretype pkcs12 -alias karun-tomcat-client-cert

~$ (optional step) keytool -import -alias root -keystore tomcat-client.jks -trustcacerts -file ~/openssl/CA/certs/karun-tomcat-root-ca.crt

<p class="lang-java prettyprint prettyprinted">

Step 4: Tomcat Changes

<p class="lang-java prettyprint prettyprinted"><!-- Make this change in server.xml of tomcat server -->
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
clientAuth="true" sslProtocol="TLS" /></p>
<p class="lang-java prettyprint prettyprinted">

Step 5: Restart Tomcat Server && check logs to ensure no errors at bootup

Step 6: Upload Client cert to browser

In your browser, eg: firefox, navigate Preferences -> Advanced -> Certificate -> View Certificates -> Your Certificates

Import “tomcat-client.p12”

Oracle STS – OnBehalfOf SAML Token Validation

There have been requests to my previous blog post on how to validate a SAML token issued by Oracle STS.

Here is the SOAP request format that should be fired on Oracle STS to validate the token:

<soap:Envelope xmlns:soap="" xmlns:trus="">
<wsse:Security soap:mustUnderstand="true" xmlns:wsse="">
<wsse:UsernameToken wsu:Id="UsernameToken-1" xmlns:wsu="">
<wsse:Password Type="">Welcome1</wsse:Password>
<wst:RequestSecurityToken Context="Id-0001313145021190-00000000008d4682-1" xmlns:wst="" xmlns:wsse="">
<wsse:KeyIdentifier ValueType="">id-McjucPrvkxXpY6m3w-8iFtvmEYQ-</wsse:KeyIdentifier>

You get SecurityTokenReference from SAML token issued by STS. You need to use it for further validation, like above SOAP request.

This returns you with the response:



Hope this helps.

SAML2.0 Weblogic Sender-Vouches Configuration & POC

June 4, 2016 8 comments

This blog post intends to highlight on the SAML2.0 configuration for web services in Weblogic. It details step-by-step guide to configure weblogic domains with a sample test client to test the web service. We will look into SAML2.0 Sender Vouches web service configuration.

What is Sender Vouches?

Sender-Vouches – The asserting party (different from the subject) vouches for the verification of the subject. The receiver must have a trust relationship with the asserting party.

Sender Vouches
1. Rather than authenticating with the STS, here, Client authenticates with an intermediate service.
2. The intermediary gets the security token from the STS.
3. Then it signs the request and sends to the RP.
4. RP trusts both the intermediary and the STS. So, it validates both of them.

Here are the steps:

  • Configure STS (Weblogic Domain – Certificate used is wssipsts
  • Configure Weblogic domain for weblogic web service with SAML2.0 Sender Vouches policy – Bob is used for this
  • Create a stand alone client that which retrieves token from STS and fires a request to web service with SAML1.1 token retrieved from STS – Alice is used for this

Configure STS:

  1. Create a weblogic domain here ‘am using weblogic 10.3.5
  2. We need to configure SSL for this domain
  3. While creating the domain I configure weblogic to use 6001 for Non-SSL and 6002 for SSL port. Let domain name be STSDomain.
  4. Now go to http://localhost:6001/console
  5. Got to STSDomain –> Environment –> Admin Server –> Keystores
    • Select Custom Identity and Custom Trust
    • Custom Identity Keystore: F:\Oracle\Middleware\user_projects\domains\STSDomain\certs\oasis.jks
    • Type: JKS
    • password: password
    • Custom Trust Keystore: F:\Oracle\Middleware\user_projects\domains\STSDomain\certs\cacerts
    • Type: JKS
    • password: changeit
    • Save and restart server if it asks to do so
  6. Got to STSDomain –> Environment –> Admin Server –>SSL
    • Private Key Alias: WssIPSTS
    • Private Key passphrase: password
    • Save and restart if asked to do so
  7. Now build the web service and deploy it in the domain. Check after successful deployment whether you can open the WSDL url or not.
  8. STSDomain–>Security Realms –>myrealm
  9. We need to configure only ‘Credential Mapper’ here. Credential Mapper basically responsible for Issuing SAML tokens. Where as identity Asserter are responsible for validating the SAML tokens. So we will configure Credential Mapper for STS and Identity Asserter for webservice
  10. Go to Providers –> Credential Mapping
  11. Add PKI Credential Mapper
    • In Provider Specific tab, Keystore Provider: SUN
    • Keystore Type: JKS
    • Keystore file name: F:\Oracle\Middleware\user_projects\domains\STSDomain\certs\oasis.jks
    • Keystore pass phrase: password
    • Use resource hierarchy and Initator group names check boxes should be selected.
    • Click on save and restart if asked to do so
  12. Add SAML2CredentialMapper
    • In Configuration –> Provider specific tab, Issuer URI:
    • Name Qualifier:
    • Default time to live: 120
    • offset: 0
    • Webservice Assertion Signing key alias: WssIPSTS
    • Key pass phrase: password
    • Select check box ‘Generate Attributes’
    • Save and go to Management tab in the same section
    • New–>New Webservice Service Provider Partner
    • Add sender vouches relying party: Sendervouches:/echoservicesaml2/EchoServiceSAML2
    • Make sure to select ‘Enabled’ check box
    • Give description
    • Audience URIs:  target:*:http://HYD-69ZRV01-L:7001/echoservicesaml2
    • Generate Attributes checkbox to be selected
    • Select confirmation methods as ‘Sender-Vouches’
    • Save and restart the server if asked to do so
  13. That’s all the configuration from STS side.

Configure Weblogic Webservice:

  1. Create a weblogic domain here ‘am using weblogic 10.3.5
  2. We do not need to configure SSL for this domain
  3. While creating domain configure weblogic to use 7001 port and no SSL port required. Let the domain name be ‘WebserviceDomain’
  4. Login to weblogic console.
  5. WebserviceDomain–>servers–>Adminserver–>keystore
    • Custom Identity and Custom Trust store
    • Custom Identity Keystore: F:\Oracle\Middleware\user_projects\domains\WebserviceDomain\certs\oasis.jks
    • Key type: JKS
    • password: password
    • Trust Keystore: F:\Oracle\Middleware\user_projects\domains\WebserviceDomain\certs\cacerts
    • Type: JKS
    • password: changeit
    • Save and restart the server if asked to do so.
    • SSL
    • Private key alias: Bob
    • password: password
    • Save
  6. Build and deploy the weblogic web service. The scripts and the webservice code is given below.
  7. Go to security realm–>myrealm–>Providers–>Authentication
    • Add SAMLAuthenticator
    • Make control Flag as ‘SUFFICIENT’
    • Make control Flag of Default Authenticator too as ‘SUFFICIENT’
    • (optional step) Also in Default Authenticator’s ‘Provider Specific’ Enable password digest, minimum password length as 1 and save.
    • (optional step) In Default Identity Asserter’s –> Common. chose Active Types ‘wsse:passworddigest’ and ‘x.509’ send it to right and click on save.
    • (optional step) In Defaul Identity Asserter –> Provider Specific. Default Username as @, Mapper attribute type as ‘CN’, select ‘use default user name mapper’ and click on Save button. Restart if asked to do so
  8. Got to security realm–>myrealm–>Providers–> Authentication
    • Add SAML2IdentityAsserterV
    • Go to Management –> New –> New Webservice Identity Provider Partner
    • Name: Sendervouches:/echoservicesaml2/EchoServiceSAML2
    • Chose Enabled
    • Audience URIs: target:*:/echoservicesaml2
    • Issuer URI:
    • Virtual User selected
    • Confirmation Method: Sender-Vouches
    • Process Attributes selected
    • Save and restart if asked to do so.
  9. That’s all the configuration of web service.

Client Testing:

  1. Open a command prompt window
  2. Run setWLSEnv.cmd from that command window to set the paths
  3. ant runsaml2
  4. That’s all for now…

Java Sample Client – Oracle Access Manager API – OAMAuthnCookie Validator

June 4, 2016 2 comments

Here is a sample Java Client code that validates the OAMAuthnCookie token. It performs 2 steps:

  1. Checks whether passed in OAMAuthnCookie token is valid and not expired
  2. Retrieves username for given OAMAuthnCookie token

OAMAuthnCookie can be found inside cookies of a browser. In the below Java client you need to put the value of OAMAuthnCookie inside the getUserNameFromToken() sessionToken.


package com.oam.test;

import java.util.Hashtable;


 * This class is a sample to extract OAM Session cookie for authenticated user
 * and to extract userid for given OAM Session token
