Abstract
A method for signing data such as software images is provided that uses modules executable by a generic client to sign hashes of the software images rather than the images themselves. The method avoids both the requirement for new or updated client software and the uploading of full software images to the signing system. This approach uses a generic client that requests and downloads processing modules from the signing system to perform the pre-processing operations in signing software images, as well as optionally for post-processing operations.
