OpenSSL Command-Line HOWTO OpenSSL Command-Line HOWTO Initial publication: June 13, 2004 Most recent revision: January 3, 2013 The openssl application that ships with the OpenSSL libraries can perform a wide range of crypto operations. The openssl command-line binary that ships with the OpenSSL libraries can perform a wide range of cryptographic operations. Documentation for using the openssl application is somewhat scattered, however, so this article aims to provide some practical examples of its use. Just to be clear, this article is strictly practical; it does not concern cryptographic theory and concepts. The nature of this article is that I’ll be adding new examples incrementally. How do I find out what OpenSSL version I’m running? Use the version option. $ openssl version OpenSSL 0.9.8b 04 May 2006 You can get much more information with the version -a option. How do I get a list of the available commands? $ openssl help openssl:Error: 'help' is an invalid command. How do I get a list of available ciphers? #! #!
Setting up public key authentication over SSH January 18, 2006 Every time I want to setup public key authentication over SSH, I have to look it up, and I've never found a simple guide, so here's mine. Generate key on local machine ssh-keygen -t rsa It will ask you for a password but you can leave it blank. Note you could also pick -t dsa if you prefer. Ensure that the remote server has a .ssh directory Make sure the server your connecting to has a .ssh directory in your home directory. Copy your local public key to the remote server If your remote server doesn't have a file called ~/.ssh/authorized_keys2 then we can create it. scp ~/.ssh/id_rsa.pub remote.server.com:.ssh/authorized_keys2 Now ssh to the remote server Now you can ssh to the remote server without entering your password. Security Now keep in mind that all someone needs to login to the remote server, is the file on your local machine ~/.ssh/id_rsa, so make sure it is secure.

PHP/Java Bridge The PHP/Java Bridge is an implementation of a streaming, XML-based network protocol, which can be used to connect a native script engine, for example PHP, Scheme or Python, with a Java virtual machine. It is up to 50 times faster than local RPC via SOAP, requires less resources on the web-server side. It is faster and more reliable than direct communication via the Java Native Interface, and it requires no additional components to invoke Java procedures from PHP or PHP procedures from Java. J2EE back end clustering and Apache load balancing are supported as well as running PHP scripts within JSP, JSF or other frameworks. The bridge uses "continuation passing" to invoke procedures/methods from each environment. Quali sono i numeri di carta di credito di prova? How to Determine if a Credit Card Number is Valid Credit cards use the Luhn Check Digit Algorithm. The main purpose of the Luhn Check Digit Algorithm is to catch data entry errors, but it does double duty here as a weak security tool.

Developers API Tutorials - Zen Cart(tm) Wiki InitSystem initSystem Introduction Why initSystem ?? The term initSystem, apart from being a tag used to group certain PHP files together in the new documentation, is meant to embrace all of those files that are automatically included/initialised before any 'command' scripts can be run. Zen Cart® v1.x uses a (non Object Oriented) page controller pattern to decide the scripts to run, based on HTTP_GET parameters. For example if main_page=login the command script would be taken from the /includes/modules/pages/login/ directory. It is application_top.php that is responsible for initialising basic subsystems (database abstraction/sessions/languages etc.) and loading global configuration data. In the following sections we will work through exactly how the Zen Cart® engine uses application_top.php to initialise core systems. application_top.php - A little bit of history From a customisation perspective this was a bad thing. application_top.php - Breakpoints The Control Array $zc_cache = new cache();

CSS: fonts Font families After the color, the font is probably the most basic property of a page. On this page I won't show any "tricks," but I will show the range of font variations that CSS allows. Since not all fonts are available on all computers (there are thousands of fonts, and most are not free), CSS provides a system of fallbacks. You list the font that you want first, then any fonts that might fill in for the first if it is unavailable, and you should end the list with a generic font, of which there are five: serif, sans-serif, monospace, cursive and fantasy. The following table shows examples of various fonts (your browser may not know all of them) and you can see what your browser does with each of the five generic ones: Font styles Most fonts have various styles within the same family, typically a bold and an italic one, often also a bold italic style, somewhat less often a small-caps and in a few cases extra-light/extra-bold or stretched/condensed versions.
