Issue Type: Bug Assignee: Unassigned Components: Security Created: 08/Feb/23 10:28 AM Fix Versions: 9.0.0 Priority: Trivial Reporter: Scott Cantor ( https://shibboleth.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A5b78efc9-1379-42cc-a3f6-56c6ea3a0007 )

I adjusted the PNRG acquisition code to use the getInstanceStrong abstraction but there is discussion online that it returns a blocking PNRG that doesn’t honor the java.security.egd property to use /dev/urandom, which would be a problem.

Santuario also implemented a change like this in (I think) the V3 branch, not ours yet, but may also need to be addressed. They might change it back, I don’t know yet, https://issues.apache.org/jira/browse/SANTUARIO-598 ( https://issues.apache.org/jira/browse/SANTUARIO-598 )

This obviously sucks because we don’t want to hardwire it, so at minimum we’re probably looking at a property-driven bean to control the algorithm and we’ll have to at least bake it into the config if not the code.
