Encryption: how big a key to you need for security? 14 digits now?

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
A few years ago, 8 digits was OK.  Then it was 12.  Now, with
Ophcrack, they say you need 14?!

But do Windows passwords use encryption like is done with WinZip?  Or
is it a weaker form of encryption that needs a longer password?  I
can't believe that  you need 14 digits for encryption for things like
PGP or WinZip encryption (probably some variant of a symmetric key)--
sounds like too much.  It would take months and months to decrypt even
12 digits I believe--on anything but a supercomputer?  There was a
website that computed how long it takes, but I can't seem to find it.

Ophcrack v3.3.1 (LiveCD v2.3.1)

    * Opchrack can crack passwords for Windows 7, Windows Vista, and
Windows XP.
    * Ophcrack can recover 99.9% of passwords from Windows XP, usually
in a matter of seconds. Any 14-character or smaller password that uses
any combination of numbers, small letters, and capital letters should
be crackable.
    * Ophcrack can recover 99% of passwords from Windows 7 or Windows
Vista. A dictionary attack is used in Windows 7 and Vista.
    * The Ophcrack LiveCD option allows for completely automatic
password recovery.
    * LiveCD method requires no installation in Windows, making it a
safe alternative to many other password recovery tools.
    * No Windows passwords need to be known to use the Ophcrack LiveCD
to crack your Windows passwords.

/*  You are most annoying.  */

Neither group you posted to have *anything* to do with encryption as you brought
it up.

You are not discussing malware so your subject matter is Off Topic for;
alt.comp.anti-virus  and has NOTHING to do with hardware associated with home
built
computers.

Please do NOT post in alt.com.anti-virus  unless you you are SPECIFICALLY
posting about
computer malware.

He's a crossposting troll that likes to insult people so he can feel

But I am superior.  And your inability to answer the question is
noted.

You're dismissed little man.

BTW you failed to explain HTTPS security as well, but then again I
don't expect much from you.

I and others have explained it, you *still* fail to understand it. Your
idea that encrypted data can magically decrypt itself without a key
shows your inability to comprehend the subject.

Plus, you are an ass.

Nope.  You failed to demonstrate why intermediary S would have a
public key, unless said key was explicitly granted by C or Z.

Until you do, *you* are the ass.

I never said anything about "S", I said *ass*.

You said data magically decrypts itself somehow and that keys weren't
involved at all. I only pointed out that the receiving entity decrypts the
data making it uncovered while at rest.

Do you want to say that my answer in this thread is wrong also, or would you
rather just cut your losses?

What "answer"?  you have FAILED to answer anything, Rafters!

Answer the question moron:  how does S, ASS, get permission to
decipher?  From C or Z or both (in your opinion, flawed as it is)?

You have FAILED to understand my answers. I don't hold any hope of you
actually understanding any of it. If you ask more concise questions, I
may have to get less general with my answers.

There you go again with the insults - It doesn't, and I never said that
it did, in fact I implied that it would remain encrypted until someone
you trusted with a *key* decrypted it (only as secure as the key
management is) - at which point you called me names and told me that
keys had nothing to do with it and that it was being magically decrypted
somehow.

You clearly don't understand encryption and the different ways it can be
used. I'm beginning to think that you don't have the capability to
understand.
***

From C or Z or both (in your opinion, flawed as it is)?

***
C and Z share a symmetric key that is unique to that session, there are
no others with a key (and yes, keys are indeed used despite what you may
think).

Are you ready to attack me for my other answer?

I'll wait.

He probably asks about viruses in the crypto groups too.

Well, hardware participants are, of course, welcomed to ignore a thread -
but just in case they are pissed off at me, or conversely interested in this
conversation, I won't continue with him in this particular thread while it
is crossposted.

Yes I wrote the tool that is in my signature.

Paid ?  No.

Not only do I not get paid for it, I wrote it to be CareWare (aka; CharityWare).

The FTP, HTTPS and the encryptions question you have posed have NOT been On
Topic.
