Glossary
ESAPI Terminology


 * adapter - There are optionally your own implementations for each security control. There may be application logic contained in these classes which may be developed by or for your organization. The logic may be organization-specific and/or application-specific. There may be proprietary information or logic contained in these classes which may be developed by or for your organization.
 * built-in singleton design pattern - The "built-in" singleton design pattern refers to the replacement of security control reference implementations with your own implementations. ESAPI interfaces are otherwise left intact.
 * codec - ESAPI encoder/decoder reference implementations.
 * core - The ESAPI interfaces and reference implementations that are not intended to be replaced with enterprise-specific versions are called the ESAPI Core.
 * exception - ESAPI exception reference implementations.
 * extended factory design pattern - The "extended" factory design pattern refers to the addition of a new security control interface and corresponding implementation, which in turn calls ESAPI security control reference implementations and/or security control reference implementations that were replaced with your own implementations. The ESAPI locator class would be called in order to retrieve a singleton instance of your new security control, which in turn would call ESAPI security control reference implementations and/or security control reference implementations that were replaced with your own implementations.
 * extended singleton design pattern - The "extended" singleton pattern refers to the replacement of security control reference implementations with your own implementations and the addition/modification/subtraction of corresponding security control interfaces.
 * ES-enable (or ESAPI-enable) - Just as web applications and web services can be Public Key Infrastructure (PKI) enabled (PK-enabled) to perform for example certificate-based authentication, applications and services can be OWASP ESAPI-enabled (ES-enabled) to enable applications and services to protect themselves from attackers.
 * filter - In ESAPI for Java, there is additionally an HTTP filter that can be called separately from the other controls.
 * interfaces - There is a set of security control interfaces. There is no application logic contained in these interfaces. They define for example types of parameters that are passed to types of security controls. There is no proprietary information or logic contained in these interfaces.
 * locator - The ESAPI security control interfaces include an "ESAPI" class that is commonly referred to as a "locator" class. The ESAPI locator class is called in order to retrieve singleton instances of individual security controls, which are then called in order to perform security checks (such as performing an access control check) or that result in security effects (such as generating an audit record).
 * reference implementation - There is a reference implementation for each security control. There is application logic contained in these classes, i.e. contained in these interface implementations. However, the logic is not organization-specific and the logic is not application-specific. There is no proprietary information or logic contained in these reference implementation classes.
 * Web Application Firewall (WAF) - In ESAPI for Java, there is additionally a Web Application Firewall (WAF) that can be called separately from the other controls.

OWASP ESAPI - .NET Edition ReadMe

Release 0.2: August 2009

Welcome to the .NET Edition of OWASP ESAPI v0.2

This document provides information about the .NET Edition of OWASP ESAPI. The topics below cover system requirements, additional product information, and application notes.

The code for the ESAPI is currently in Google Code.

Download the latest .NET ESAPI library binary from Google Code here.

Download the latest .NET ESAPI documentation from Google Code here. It is a zipped .chm (help) file.

You can also browse the .NET ESAPI documentation here

To download and work with the source you must use an SVN tool.

AnkhSVN is a free SVN tool that integrates with Visual Studio. Point your SVN tool at http://owasp-esapi-dotnet.googlecode.com/svn/trunk. Anonymous checkout is supported.

You can also browse the source.

System Requirements

The solution is created with VS 2008 and .NET 3.5. However, the actual code should be compatible with .NET 2.0, so it should be simple to get the code to compile in most environments. Troubleshooting

Other Requirements

The .NET Edition of OWASP ESAPI includes a reference implementation which may be tailored or replaced, according to your organization's needs.

You must also download download and install the latest version of the AntiXss library.

Server Recommendations

None

Obtaining the .NET Edition of OWASP ESAPI

There are a couple of ways to get started with the .NET ESAPI.

If you simply want to start using the functionality, you can download the assembly from [ Google Code]. You will also need to add the appropriate configuration (see here).

You can download the solution from Google Code with SVN.

You will need to download and install the AntiXss library separately, in order to respect the code licensing.

The SwingSet application requires you to login - just register a username and go. You also need to supply a SMTP host in the web.config file in SwingSet in order to register a user, so that you can get an activation email. I might change this in the released version, since it's sort of a pain. You can just use the external SMTP server for an email account you own and use that - i.e.

README

Requirements:

If you have setuptools installed, you should be able to install all except KeyCzar and Visual C++ 2008 by doing 'easy_install ' in a shell or command prompt.


 * PyCrypto 2.01 - http://www.amk.ca/python/code/crypto
 * PyCrypto requires a C Compiler. Windows users can us Visual C++ 2008 Express Edition - http://www.microsoft.com/express/vc/#webInstall
 * KeyCzar 0.6b - http://www.keyczar.org/
 * KeyCzar requires PyASN1 - http://pypi.python.org/pypi/pyasn1
 * and simplejson, which is standard in 2.6 - http://pypi.python.org/pypi/simplejson
 * PyLint 0.18.1 - Only needed for static analysis. - http://pypi.python.org/pypi/pylint
 * Coverage module by Ned Batchelder v3.0.1 - Only needed if you want coverage analysis - http://pypi.python.org/pypi/coverage/3.0.1
 * Nose 0.11.1 - Only needed if you want to run unit tests together and combine it with coverage analysis - http://pypi.python.org/pypi/nose/0.11.1

Installation:
 * Install any of the missing dependencies listed above.
 * Extract the ESAPI on Python package.
 * Add the extracted folder to your Python path. One way to do this is to create a text file, such as 'esapi.pth', in your Python installation's Lib\site-packages folder. Copy the path of the folder you extracted into this text file. The path should have the 'esapi' folder inside.
 * Start a new interactive Python console and enter 'import esapi'. If you get no output, it ran successfully. If you got "ImportError: No module named esapi", double check the step above.
 * By default, ESAPI is set up for Linux. If you are running ESAPI on Windows, you will need to modify the Encryptor_KeysLocation and Executor_WorkingDirectory settings in esapi/conf/settings.py. You should use forward slashes in the paths.
 * See "To set up a crypto keyring" to generate the keys necessary for crypto.
 * Run the unit tests by opening a shell or command prompt in esapi/test and running runTests.bat or runTests.sh, depending on your platform. If you get around 7 errors relating to crypto, please ensure you have followed the steps under "To set up a crypto keyring".
 * Note: Running all tests may appear to block or pause, particularly on Windows. This may be be due to exhaustion of the entropy pool. If it blocks, try moving the mouse, typing, or generating some disk activity.

To adapt and integrate with your project:
 * You can use as much or as little of ESAPI as you would like. You'll want to do a 'from esapi.core import ESAPI' and use the methods that class provides.

To set up a crypto keyring:
 * Select a root directory for your keyring, like /esapi/keyring/, and set Encryptor_KeysLocation in settings.py to this string if you have not already.
 * Open a python interactive shell and execute:
 * from esapi.core import ESAPI
 * ESAPI.encryptor.gen_keys
 * Modify esapi/conf/settings.py according to the output by replacing the Encryptor_MasterSalt line with the one given.

To enable internationalization:
 * Set the 'LANGUAGE' environment variable with your locale
 * On *nix: export LANGUAGE=en_US
 * On Windows: set LANGUAGE=en_US
 * Please note that as of this writing, no translation files are available. A GNU gettext .po file is available in esapi/conf/locale.

JavaScript
