Why no linux version ?
I think Etar only does Windows releases.
Anyway, this is the script I promised I'd show you guys in my previous post:
https://gist.github.com/ZenulAbidin/cbe69f8a2496514773140516e3666519You give it any public key in the file input.txt, adjust the script values such as the number of trailing bits, number of results etc. and it will print you the list of most likely public keys.
Warning: bit numbers >20 will cause you to run out of memory fast. Also it might take about an hour or so to complete depending on the bit size. I am working on a fix for both of these.
Can`t say. I use PBv5.31 to compile app. It is licensed version(not cracked or so.) But I think if the other more well-known antiviruses did not find anything, then this is a false alarm. And so decide for yourself.
I wouldn't worry about it given that only 3 obscure AV vendors flagged it. Perhaps they don't like CPU-intensive loops with multiple threads.

Does this one has the same cmd line as the other recent script you posted, because its not doing anything.
