howzar

howzar appears to be a registered nickname in the Bitcoin OTC Web of Trust ecosystem. The Bitcoin OTC site hosts profiles tied to user nicknames and their GPG identities, and the link in question (viewgpg.php?nick=howzar) would be the place to view any associated GPG identity for that nickname. However, publicly accessible biographical details or verifiable personal information for “howzar” beyond the OTC trust data are not readily available in the sources I can access here.

In short: howzar is a Bitcoin OTC Web of Trust user nickname; further identity details would be found on the OTC profile page if the user has publicly posted them, but such specific data isn’t available in my current view.
