[JIRA] Commented: (SSPCPP-376) Add a post-filtering hashing feature to shorten long attributes, namely ePTIDs

Scott Cantor commented on SSPCPP-376:
-------------------------------------

This is patently obvious to me now, but the obvious thing to do here is add a resolver plugin that does the hashing and generates a new attribute. That keeps the original around as needed.

> Longish attribute values like the ones for eduPersonTargetedID can lead to problems within applications, which do not expect that long values and are not able to store them in their internal storage. A good example is JIRA itself.
> If the SP could generate a hash for such long attributes, the problem would disappear, without having to wait for a fix of the application itself.
> In order to still be able to track back user activity, it will be necessary that the SP logs (or stores?) enough details about hashes it generated.
