Abstract
A method, system, and computer readable code for validating that a document or executable to be served from a server is the same original document or executable placed on the server by the legitimate author or owner. Digital signatures are stored with each file available for serving from, or executing from, a server. When a file is requested by a user, the contents of the requested file are validated (i.e. authenticated) using this digital signature. If the validation does not succeed, the file is not served to the user—instead, the user is told that the requested file was not found. A number of optimizations are defined, including caching validated files and/or caching computed digests.
