I am trying to find a way to "hash" the contents of an XML file. At the root of this is a need to compare some text nodes that are passed in to text nodes that I am expecting to make sure that the checksum is the same. The passed-in text nodes have returned from a form submission and I need to ensure that they were not changed (within reason, ruling out collisions).
The architecture is horrible, so please don't ask about it! I am locked in to a given implementation of sharepoint with some very bad custom code that I need to work around.
Is there a well-performing checksum/hash function that can be implemented? I would need to check about 100 text nodes.
