Secure Hash Algorithm 256 (SHA-2 or SHA-256) support on Symantec Code Signing for Individuals and Symantec Code Signing for Organizations is available starting April 1st, 2013 on the following Symantec Code Signing platforms: Microsoft® Authenticode™, Java™, Adobe® Air® and Microsoft® Office Visual Basic® for Applications (VBA). You will be able to select the option for SHA-2 through the ordering pages, reissue process and via the Application Programmatic Interface (API) for QuickOrder, QuickInvite and Reissue.

SHA-2 was published by National Institute of Standards and Technology (NIST) as U.S. Federal Information Processing Standard.

Please note that some older applications and operating systems do not support SHA-2, for example, Windows™ XP Service Pack 2 or lower does not support the use of SHA-2. Java SDK 1.4.2 or higher needs to be installed and used on the server for SHA-2 support for Java server support.

If you are using a Windows environment, please refer to the following blog for SHA-2 deployment:

Please refer to  for SHA-2 deployment on Java servers.

In addition, Apache™ version 2.x or higher is required to support SHA-2 on Apache based servers and Open SSL 1.1.x will be required  for certificate signing request and private key generation.

SHA-2 support is available to you as option in securing your code signing certificates. Please select the secure hash algorithm that is aligned with your corporate policy.

Thank you for this enhancement!

Just to clarify one point, Windows XP SP3 does not support SHA-2 Authenticode certificates, even though it provides limited SHA-2 support elsewhere:

"...the S/MIME signed e-mail verification and the Authenticode signature verification do not support the SHA2 hashing algorithms on a computer that is running Windows XP SP3. " (see the "More Information" section), and

So as a publisher of an Authenticode-signed ClickOnce app, I'm having to use SHA-1 until a larger portion my clients upgrade from XP.
