As2 files

A Directory Monitor allows you to capture events on local directories behind your firewall. For instance, a directory monitor can detect when a file is added, when a file is deleted, or when a file undergoes changes. The monitor we're about to create will be monitoring a directory for any new file additions.

This can be useful in cases where, as part of a business process process, an EDI document is placed into the monitored directory for transmission. As soon as our server detects that a file has been added into the monitored directory, it will automatically grab that file and forward it to the designated trading partner through an AS2 connection. It's now time to create the directory monitor in question.

Go to the Directory Monitors menu and click the Add button. Give the monitor a name, e. After, that, click the Browse button, navigate to the directory you want to monitor and select it. After you do that, the Directory field will then be populated with the path to that directory e. Note that the Monitor interval is set to seconds.

Despite this protocol and its predecessor AS1 having existed since the s, very few people know what it is or how it works. Upgraded from the original and aptly labelled AS1 protocol, that was created in the s, AS2 supports the encryption of files usually known as messages that are then exchanged with trading partners using HTTPS. Usage of AS2 is commonly found in EDI processes - where messages are often exchanged for the purpose high volume and automated ordering. In this example, the files are saved with different extensions according to their type, and their appropriate SEF files are loaded.

The file content is obtained by first extracting the message for the AS2 document. This is accomplished by doing the following:. At this point, the state of the message can be encrypted, signed, or encoded in base64, or just plain text. The process method can process the message at any of these states just by calling the line:. However, to break the process into steps would make it easier to troubleshoot the program should a problem occur during the process of "unwrapping" the message. Note that when the message is getting unwrapped, the header information of the message will change to describe the message at its present state.

Some headers may even be excluded from the original state of the message like the "Receipt-delivery-option". So the values of this particular header were saved before any processing was initiated because they will later be needed when sending MDN asynchronously.

Also note that the certificate names, encryption and assurance algorithms are not specified in the program when deciphering the message because those information are in the message itself. What needs to be specified however, is where the certificates are located.

The certificates for the AS2 Server have to be stored in the "LocalMachine" folder in the "Machine Key Sets" certificate store because ASP applications do not use an interactive login account when accessing certificates as opposed to desktop applications, which locate their certificates in the "CurrentUser" folder in the "User Key Sets" certificate store.

When an AS2 file is loaded into the mailDocument object, it checks the file for the presence of the "Disposition-Notification-To" header. The MDN object must have earlier been instantiated with the following command:. However, it still has to check for the presence of the "Receipt-delivery-option" header to see if the MDN should be sent synchronously or asynchronously. Security is achieved by using digital certificates and encryption.
