To add onto this, when it comes to "classified" information, it generally falls into two types: 1. Actual classified information (Secret, TS, SCI, SAP). This information is classified by people with clearances according to a set of guidelines and all information has to be more or less manually classified. If you were to independently produce this information (without knowledge or information from the classified project), you are legally in the clear to publish. 2. Restricted information (RD, FRD, SNM). Unlike with classified information, what is or isn't considered restricted is regulated by the DOE. Because of this, information can be "restricted at inception" which prevents it from being published regardless of how it was obtained or produced. Point being that just because information isn't classified and you may have acquired it through independent means, you can still be restricted from sharing it because the US has deemed it "inherently dangerous" to national security. Note: I don't think the code in question could by any stretch be considered RD or FRD.
