1. Per the spec, there is only interface authentication in OSPF. The "area # authentication" is a shortcut macro that Cisco made. Keys are still done at the interface. Best practice is whatever makes your life easier and accomplishes what you want. Newer versions of IOS require send/accept on keys, older ones assume it's valid. in the grand scheme of things, it's best to be as detailed as possible. This helps you know exactly what is, or is supposed to be happening. 2. Windows calculator - scientific mode. Click hex. Paste the number in. Click Decimal. Poof. There it is.
