The canonical file works almost the same as the generic file but will translate received messages instead. This will rewrite messages that have may have invalid or incorrect domains or usernames to valid ones that are present on the server. The format of the canonical file is sourceaddress newaddress where sourceaddress is the incoming email address and newaddress will be its translated address. For example, Ms. Ging s local email username ging.ging was changed recently to ging. Her colleagues will be certain to use her old local email username to send messages to her, which will result in bounced email. This can be solved by adding the following entry to the canonical file: ging.ging ging When emails are received by Postfix for the ging.ging email address, it will be rewritten to ging. The new value will be used by the other database files such as aliases and will be given to the correct user. If you change entries on the canonical file, you will also have to update its database file by running postmap /etc/postfix/canonical. To use the canonical file in Postfix, you will need to add the canonical_maps parameter in your main.cf file, like this; canonical_maps = hash:/etc/postfix/canonical and restart Postfix. asp.net upc-a Barcode UPC-A - CodeProject

The first thing we do is get a suitable key and initialization vector for our cryptographic algorithm. These are the two parts of the secret key that are shared between whoever is encrypting and decrypting our sensitive data. A detailed discussion of cryptography is somewhat beyond the scope of this book, but here are a few key points to get us going. Unenciphered data is known as the plain text, and the encrypted version is known as cipher text. We use those terms even if we re dealing with nontextual data. The key and the initialization vector (IV) are used by a cryptographic algorithm to encrypt the unenciphered data. A cryptographic algorithm that uses the same key and IV for both encryption and decryption is called a symmetric algorithm (for obvious reasons). Asymmetric algorithms also exist, but we won t be using them in this example. Needless to say, if an unauthorized individual gets hold of the key and IV, he can happily decrypt any of your cipher text, and you no longer have a communications channel free from prying eyes. It is therefore extremely important that you take care when sharing these secrets with the people who need them, to ensure that no one else can intercept them. (This turns out to be the hardest part key management and especially human factors turn out to be security weak points far more often than the technological details. This is a book about programming, so we won t even attempt to solve that problem. We recommend the book Secrets and Lies: Digital Security in a Networked World by Bruce Schneier [John Wiley & Sons] for more information.) We re calling a method called SelectKeyAndIV to get hold of the key and IV. In real life, you d likely be sharing this information between different processes, usually even on different machines; but for the sake of this demonstration, we re just creating them on the fly, as you can see in Example 11-52. If you have users who have changed locations within the organization, such as to another building, relocated can help inform senders about it. An entry in the relocated file looks like this: pattern new_location where pattern is usually the email address that the transferred person has and new_location is a helpful message that can inform the sender of the new whereabouts. The sender will be notified based on the value of new_location and the email will not be sent. Here are sample entries for the relocated file: ging@example.com ging Ms. Ging changed her address to ging@example.org This address is not valid anymore private static void SelectKeyAndIV(out byte[] key, out byte[] iv) { var algorithm = TripleDES.Create(); algorithm.GenerateIV(); algorithm.GenerateKey(); key = algorithm.Key; iv = algorithm.IV; } TripleDES is an example of a symmetric algorithm, so it derives from a class called SymmetricAlgorithm. All such classes provide a couple of methods called GenerateIV and GenerateKey that create cryptographically strong random byte arrays to use as an
