About Timestamping
When you sign an Adobe AIR application with a digital certificate, the packaging tool queries the server of a timestamp
authority to obtain an independently verifiable date and time of signing. The timestamp obtained is embedded in the
AIR file. As long as the signing certificate is valid at the time of signing, the AIR file can be installed, even after the
certificate has expired. On the other hand, if no timestamp is obtained, the AIR file ceases to be installable when the
certificate expires or is revoked.
By default, the Adobe AIR Extension for Dreamweaver obtains a timestamp when creating an Adobe AIR application.
You can, however, turn timestamping off by deselecting the Timestamp option in the Digital Signature dialog box. (You
might want to do this, for example, if a timestamping service is unavailable.) Adobe recommends that all publically
distributed AIR files include a timestamp.
The default timestamp authority used by the AIR packaging tools is Geotrust. For more information on timestamping
and digital certificates, see
Digitally signing an AIR file.
Editing associated AIR file types
You can associate different file types with your Adobe AIR application. For example, if you want file types with an .avf
extension to open in Adobe AIR when a user double-clicks them, you can add the .avf extension to your list of
associated file types.
1 In the AIR Application and Installer Settings dialog box, click the Edit list button next to the Associated File Types
option.
2 In the Associated File Types dialog box, do one of the following:
Select a file type and click the minus (-) button to delete the file type.
Click the plus (+) button to add a file type.
If you click the plus button to add a file type, the File Type Settings dialog box appears. Complete the dialog box
and click OK to close it.
Following is a list of options:
Namespecifies the name of the file type that appears in the Associated File Types list. This option is required, and
can only include alphanumeric ASCII characters (a-z, A-Z, 0-9) and dots (for example, adobe.VideoFile). The
name must start with a letter. The maximum length is 38 characters.
Extensionspecifies the extension of the file type. Do not include a preceding dot. This option is required, and
can only include alphanumeric ASCII characters (a-z, A-Z, 0-9). The maximum length is 38 characters.
Descriptionlets you specify an optional description for the file type.
Content Typespecifies the MIME type or media type for the file (for example text/html, image/gif, and so on).
Icon File Locationslets you select custom images for the associated file types. (The default images are Adobe AIR
images that come with the extension.)
