Abstract
Methods and computing devices enable code and/or data software on computer devices to be verified using methods and signatures which can be updated by a signing server after distribution. Updated verification methods and signatures may be provided in a second signature file. When a computing device unpacks an application for execution it may check whether a second signature file is associated with the application file. If not it may connect to a signing server to request a second signature file for the software. The signing server then may request information related to the software sufficient to determine if the software is trustworthy. If determined to be trustworthy, the signing server can send a second signature file to the computer device for use in verifying the software henceforth. The second signature file may include new or modified verification methods and a new signature.
