by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:

documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify

liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf

SAML Response Generator
=======================
This is a small utility program that makes it easy to generate SAML responses for testing.
Creating Private and Public Keys for Testing
--------------------------------------------
You will need to generate a private and public key to use for generating saml assertions. The following steps are used for creating the keys:
```
#create the keypair
openssl req -new -x509 -days 3652 -nodes -out saml.crt -keyout saml.pem
#convert the private key to pkcs8 format
openssl pkcs8 -topk8 -inform PEM -outform DER -in saml.pem -out saml.pkcs8 -nocrypt
```
Command line tool
-----------------
You will need to create the jar file in order to use the command line tool. cd to saml-tutorial then run 'mvn package' to create a jar file called 'saml-generator-1.0.jar'. This jar file will be used to create saml assertions.
Usage
-----
java -jar saml-generator-1.0.jar [-domain <arg>] [-issuer <arg>] [-privateKey <arg>] [-publicKey <arg>] [-roles <arg>] [-email <arg>] [-samlAssertionExpirationDays <arg>] [-subject <arg>]
```
-issuer
The URI of the issuer for the saml assertion.
-subject
The username of the federated user.
-domain
The domain ID for the federated user.
-roles
A comma separated list of role names for the federated user.
-email
The email address of the federated user.
-publicKey
THe path to the location of the public key to decrypt assertions
-privateKey
The path to the location of the private key to use to sign assertions
-samlAssertionExpirationDays
How long before the assertion is no longer valid
```
Example
-------
java -jar saml-generator-1.0.jar -domain 7719 -issuer 'http://some.compnay.com' -privateKey saml.pkcs8 -publicKey saml.crt -roles 'role1' -samlAssertionExpirationDays 5 -subject samlUser1
