4. Asset integrity check
Date: 2020-02-23
Status
Accepted
Context
In HTML5, link and script nodes have an attribute named integrity, which lets the browser check if the remote file is valid, mostly for the purpose of enhancing page security.
Decision
In order to replicate the browser's behavior, the program should perform integrity check the same way it does, excluding the linked asset from the final result if such check fails.
The integrity attribute should be removed from nodes, as it bears no benefit for resources embedded as data URLs.
Consequences
Assets that fail to pass the check get excluded from the saved document. Meanwhile, saved documents no longer contain integrity attributes on all link and script nodes.
