I realize this is an older topic, but it bears noting:

Password protecting is done largely to prevent hosting services and unwelcome busybodies from prying into the contents of the archive. Many filehosts don't explicitly deny uploading of password protected archive files; however the vast majority of them DO automatically inspect uploaded files for disallowed content (and their TOS will say so). If the host's robot cannot open an archive, it can't delete the listing due to content violation. Did you ever upload a video clip to YouTube, only to discover it added commercials to it in spite of you unchecking that little box? Notice that it correctly identified the original media you clipped it from - it's done by generating a spectrum, or "thumbprint" of the content via Fourier transform, and comparing it against known spectra of copyrighted media. Filehosts and cybercops use this, and binary diff (for applications), to sniff out the goods. Again, if a robot or Interpol agent cannot read the contents, there's nothing to compare. Welcome to 1984, Big Brother now has top-end computers to do the Watching for him.
As far as torrents are concerned, again, it greatly complicates the task of "humans" whose sole mission it is to discover content which may infringe on copyrights or break other dark laws.
A .rar file called {some movie title here} cannot be matched to the actual content it may claim to be, and it's usually problematic at best to discover from whence comes the redirection from listing (where the password is mentioned) to the actual file inside the archive... you see their problem They actually have to
think and work.
tl/dr:
The password protected archive scheme avoids messy deletions and DMCA takedowns, and who-knows-whatever-else.

To expand on OP:
Now we know how to quickly ID a p/w .rar... but
If you get a p/w .rar, and you don't know the password, you:
a. have found a disallowed torrent in TPB, or
b. have missed the p/w in the description.
Besides, while accurate, OP's approach is a tad convoluted... the best way to know if the .rar is protected is to
simply try to open it!! You'll be asked for the password if there is one.
Knowing TPB's policy on password protected files; this becomes pretty much a moot point. You
should already know if what you're downloading is p/w protected.
Really, the tutorial in the OP is only useful IF you have a file that's taking a long time to d/l, AND you're impatient, AAAAND you haven't noticed a password given in the description (or assumed there wasn't one). Wondering if a rar is p/w before the d/l is finished is a long exercise in short logic.

Also:
THERE IS NO SUCH THING AS A RAR PASSWORD CRACKER - it's a pipe dream.
There *are* scripts and tools that can attempt to bruteforce a .rar password (if you call that cracking lol), but of course, the password will have to be retardedly simple enough to hax in a basic dictionary attack in anything like a human lifespan.
ALL promises of the Fabled Golden RAR Cracker are
guaranteed to be vectors for shitware, so if you care to dabble, grab your buttcheeks and bend over, unless you're doing forensics in a sandbox and/or VM (in which case you're already in-the-know).
WinRAR uses an EXTREMELY tight encryption algorithm, (
elliptic curve cryptography) so unless you have like 750 quintillion years to sit around waiting for a hash to resolve, move on to something else.
