Authentication typically happens once per connection setup between two parties. Keys that are used to help carry out the authentication are called identity keys. The lifetime of a principal might be long (e.g., decades), and such keys need to have lifetimes that are of the same order of magnitude as that of the principal.

GLIB_CHECK_VERSION (major, minor, micro)

In listing 22.1 we register our portable area. It s similar to the regular AreaRegistration classes we wrote in chapter 21, with one additional required step: we must call base.RegisterTheViewsInTheEmbeddedViewEngine(GetType()) B. That call allows us to use a special view engine (also included in MvcContrib) that makes our embedded views available to the consuming project. The embedded views are the trick behind portable areas. When our consuming project needs a view, the special embedded view engine can find them. If we didn t use this view engine, we d have to automate our deployments so that each portable area s views were in the correct spot in our project s filesystem. Even though this can be automated, using embedded views allows us to skip this tedious and error-prone step. In the next section, we ll use the portable area in our consuming application.

In addition to the version information presented in Table 6-2, you can also use glib_check_version() to check the version of GLib currently in use at runtime. This function returns NULL, if the library is compatible, or a string that gives more information about the incompatibility. This function makes sure that the runtime version is the same or a more recent release. const gchar* glib_check_version (guint major, guint minor, guint micro); GLib also provides a number of additional macros that do everything from numerical operations, type conversions, and memory referencing to simply defining Boolean values for TRUE and FALSE. A list of some of the most useful macros can be found in Table 6-3. Table 6-3. Standard GLib Macros

Once two parties have, say, authenticated themselves to each other using their identity keys, they may want to start exchanging confidential information with each other. To do so, they

When we have our portable area class library project with its controllers and embedded views, we must configure our consuming application so that it can use them. MvcContrib makes this easy. As well as registering the area, we also need to call InputBuilder.BootStrap in Global.asax.cs, as shown in listing 22.2.

protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); MvcContrib.UI.InputBuilder.InputBuilder.BootStrap(); }

may agree on a conversation key, or session key. (We use the terms conversation key and session key interchangeably.) A key issue with session keys (pardon the pun!) is how to have two parties agree upon one. Alice and Bob can meet at some physically secure place and agree on a password. The password can then be converted to bits,1 and be used to encrypt a session key that Alice sends to Bob (or vice versa). Alternatively, Alice could call Bob over the phone, and as long as the phone line is not wiretapped, they can decide on a password. That password can be used to exchange a conversation key in a similar way, which can then be used to securely communicate over some channel, such as an Internet socket. It is possible for Alice and Bob to agree upon a key without ever meeting or communicating over an alternate secure channel using an asymmetric cipher such as RSA or the Diffie-Hellman (DH) key exchange algorithm (described in Section 14.4.2).

Return the absolute value of argument a. This function simply returns any negative number without the negative sign and does nothing to positive numbers. Make sure that a is between low and high. If a is not between low and high, the returned value will be the closest of the two. Otherwise, the returned value will be left unchanged. On UNIX machines, directories are separated by a slash (/), and on Windows machines, they are separated by a backslash (\). G_DIR_SEPARATOR will return the appropriate separator as a character, and G_DIR_SEPARATOR_S will return the separator as a string.

The call to AreaRegistration.RegisterAllAreas will look for any assemblies in the bin folder if our portable area project is referenced by the consuming application, it goes there automatically. If our consuming application doesn t reference the portable
