Vendor specific attributes format eapol_test

Hello, I know it’s not FreeRADIUS related but you may be able to help me to understand how vendor specific attributes work and how to correctly send them with eapol_test. Vendor specific attributes are in the RADIUS attribute 26 So with eapol_test the following flag `-N 26:x:00009f680305010000` would be in detail: 00009f68 = Vendor-Id in hex 03 = Vendor attribute id 05 = length 010000 = Value 05 should be the length if I understand it correctly. But after playing around a bit it confuses me more and more. Why is 010000 of length 05 and e.g. 11000342342342 of length 09? BR, Lineconnect
