Signing an application with a digital certificate
A digital signature provides an assurance that the code for an application has not been altered or corrupted since its
creation by the software author. All Adobe AIR applications require a digital signature, and can’t be installed without
one. You can sign your application with a purchased digital certificate, create your own certificate, or prepare an Adobe
AIRI file (an Adobe AIR intermediate file) that you’ll sign at a later time.
1 In the AIR Application and Installer Settings dialog box, click the Set button next to the Digital Signature option.
2 In the Digital Signature dialog box, do one of the following:
• To sign an application with a pre-purchased digital certificate, click the Browse button, select the certificate, enter
the corresponding password, and click OK.
• To create your own self-signed digital certificate, click the Create button and complete the dialog box. The
certificate Type option refers to the level of security: 1024-RSA uses a 1024-bit key (less secure), and 2048-RSA
uses a 2048-bit key (more secure). When you’re finished click OK. Then enter the corresponding password in the
Digital Signature dialog box and click OK.
• Select Prepare an AIRI package that will be signed later and click OK. This option lets you create an AIR
Intermediate (AIRI) application without a digital signature. A user is not able to install the application, however,
until you add a digital signature.
