Now that we have covered a number of key security concepts, let us examine how those concepts work together in a typical web client/web server interaction. Suppose Alice is an employee of a company called PCs-R-Us, and her job responsibility is to order DVD drives for the company s PCs from a company called DVD-Factory. DVD-Factory has a web site that Alice uses to procure DVDs for her company. The following points examine why DVD-Factory might want to care about the security goals discussed in this chapter when implementing its web site. Authentication: If a malicious competitor is trying to steal business from DVD-Factory, the competitor could create a web site that looks exactly like the DVD-Factory web site, but at a different web address. To combat that tactic, DVD-Factory needs to make sure that the web server can be authenticated so that when Alice goes to the DVD-Factory web site, she knows she is dealing with DVD-Factory and not DVD-Factory s look-alike competitor. The SSL protocol is used between web clients and web servers to do secure transactions. When Alice enters the web address https://www.dvd-factory.biz, Alice s browser will invoke the SSL protocol to make sure that the web site authenticates itself to her browser. (We will talk more about how the SSL protocol accomplishes this later in the book, but at this point, it is important to note that the web browser authenticates the web site to make sure that it is dealing with DVD-Factory s web site and not another web site that is trying to spoof or imitate it.) java ean 13 generator how to calculate the check digit ( EAN - 13 ) barcode symbologies ...

Add the list() action: def list(self): c.pages = meta.Session.query(model.Page).all() return render('/derived/page/list.html') The list() action simply gets all the pages from the database and displays them. Notice the way you use the template context object c to pass the page data to the template. Create a new file named templates/derived/page/list.html to display the list of pages: <%inherit file="/base/index.html" /> <%def name="heading()"> <h1 class="main">Page List</h1> </%def> <ul id="titles"> % for page in c.pages: <li> ${page.title} [${h.link_to('visit', h.url_for(controller='page', action='view', id=page.id))}] </li> % endfor </ul> The h.link_to() helper is a tool for generating a hyperlink, of course you can also write the <a> tag out yourself if you prefer. To use it add the following import to the end of lib/helpers.py: from webhelpers.html.tags import link_to If you visit http://127.0.0.1:5000/page/list, you should see the full titles list, and you should be able to visit each page. java barcode ean 13 Generateing EAN - 13 barcodes with Javascript and SVG - Rene ...

JavaScript barcode generator and library. Create any barcode in your browser. Extending Qt is one thing, but making your own application extendable is quite another. It not only involves implementing a given interface; you must also design the interface, look for plugins, load them, and then use them. This is one of the areas where there traditionally have been lots and lots of platform quirks to take into account. With Qt almost all of these quirks go away, and you can focus on providing your users with a modularized and extendable design. Label(s) delete() This chapter began with an image file format plugin for Qt; it continues by creating an image filtering application in which the filters are provided as plugins. A quick glance of what to expect can be seen in Figure 11-5: filters are on the left and right; the original image appears above the filtered image. 4. List three advantages/disadvantages of using a web of trust model vs. using a certificate authority based trust model. 5. Extend the AESEncrypter program of Section 12.1.6 to compute and verify a MAC on the message in addition to encrypting and decrypting data. Be sure to use different keys for the encryption and MAC computations. 6. State how you can use symmetric encryption to achieve (a) authentication, (b) confidentiality, and (c) message integrity. 7. Write a Java program that computes HMAC-SHA-256. Use the Mac class in the Java Cryptography library. Do not write a program that constructs HMACs using the MessageDigest class, or attempt to write your own implementation of a hash function! Your program should accept a key file as a command-line argument (similar to the AESEncrypter program in Section 12.1.6), and should use the standard input and output streams. The program should output a base64- or hex-encoded 256-bit keyed hash of its input. 8. Learn about the openssl and/or Java keytool command-line utility programs. Use them to generate an RSA key pair, and generate a certificate-signing request that you could submit to a CA. 9. Add a secure logging feature to SimpleWebServer. The secure logging feature should write an integrity check code to each log entry. Use a MAC to protect each record and the entire file. What are the performance challenges in including such functionality Users of the application might want to be able to delete a page, so let s add a delete() action. Add the following action to the page controller: def delete(self, id=None): if id is None: abort(404) page_q = meta.Session.query(model.Page) page = page_q.filter_by(id=id).first() if page is None: abort(404) meta.Session.delete(page) meta.Session.commit() return render('/derived/page/deleted.html') This page searches for the page to be deleted and aborts with a 404 Not Found HTTP status if the page doesn t exist. Otherwise, the page is deleted using the Session object, and the changes are committed. Add the templates/derived/page/deleted.html template with the following content to display a message that the page has been deleted: java barcode ean 13 EAN13 . java · GitHub
