About

OWASP Tools Project Enterprise Security API (ESAPI) OWASP Enterprise Security API Toolkits help software developers guard against security-related design and implementation flaws. 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. Further development of ESAPI occurs through mailing list discussions and occasional workshops, and suggestions for improvement are welcome. For more information, please contact us. ESAPI Toolkits Java EE .NET Classic ASP PHP ColdFusion & CFML Python Haskell How ESAPI Works ESAPI Toolkits are designed to automatically take care of many aspects of application security, making these issues invisible to the developers.

Latest News ESAPI Java 2.0preview1 has been released ESAPI Python version project is starting up. Please contact [email protected] for more information. The Cold Fusion implementation project has started. It will build on the Java API, using wrappers for CFML. ESAPI has been through a line-by-line review by a major systems integrator. We will post all the findings soon but they are pretty minor. Request for users/adopters/supporters. Please let us know your stories! ESAPI News Archives ESAPI Mailing List Sample Application - ESAPI Swingset The ESAPI Swingset sample application is under development. Many lessons have been completed that demonstrate how to leverage ESAPI to protect a web application. It also demonstrates the flaws web applications can have if they are not ESAPI-enabled.

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.

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.

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.

   <mailSettings>
     <smtp from="[email protected]">
       <network
            host="you fill this part in, for example d.mx.mail.yahoo.com for a yahoo.com mail account"
            port="25"
            />
     </smtp>
   </mailSettings>

OWASP ESAPI - Python Edition

Python Edition of OWASP ESAPI v1 BETA Has Been Released

I'm pleased to announce that a beta of version 1 has been released. To get a copy, go to our Google Code site to clone the Mercurial repository or download an archive. Documentation for the API is available here.

This beta has been tested on Python 2.6 on Windows and Linux, but other versions have not been tested. If you take a look, I would appreciate it if you would send me an email about your experience.

README

Requirements:

If you have setuptools installed, you should be able to install all except KeyCzar and Visual C++ 2008 by doing 'easy_install <packagename>' 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 .

Haskell

Haskell Edition of the OWASP ESAPI Toolkit - First release is under development

• The Haskell version of ESAPI is being lead by Sigbjorn Finne. Feel free to contact him at sof 'AT' galois.com for further details.
• Details below will be filled in as work progresses. Volunteers wanted!

OWASP ESAPI - Haskell Edition ReadMe

Sigbjorn (and Galois, who is his employer) are contributors to the core Haskell language. The intent of this effort is to make ESAPI for Haskell part of Haskell itself.
