Cloud-based code signing service—hybrid model to avoid large file uploads

摘要

Techniques are disclosed for reducing the amount of data associated with code signing files in a cloud-based computing environment. In one embodiment, a cloud-based code signing component receives a request to sign a current version of a file. The request includes differences between the current version of the file and a previous version of the file. The cloud-based code signing component reconstructs the current version of the file based on the differences between the current version of the file and the previous version of the file. The cloud-based code signing component signs the reconstructed file, and determines differences between the signed file and the reconstructed file. The cloud-based code signing component transfers the differences between the signed file and the reconstructed file to a user.
