Right. So nobody has every paid you for your tool.  I wonder how many
downloads you even have of it.

Nope.  Wrong.  People concerned with PCs are concerned with security.
We are not all overclocker hobbyists you know.

PCTipp has and displays the numbr of downloads since I allowed them to host it
on PCTipp
Magazine.  That is not the whole story either since it was originally hosted on
another
size.

Wrong.

hardware.PC-homebuilt is about just that hardware for home built computers like
mine based
upon an ASUS motherboard.

alt.comp.ant-virus  is concerned with specifically malware.  Not generalized
security.
That is what alt.computer.security  is about.  When I told you that last time,
instead of
reposted your OT subject matter there you reposted it here and there.  Most
annoying and
borders on abusive.

If you were discussing a worm that encrypted its data flow to a dump site or a
ransom
trojan that encrypted data files on your system and held the key for ransom,
then it would
be On Topic for  alt.comp.anti-virus but still would be OT for
alt.comp.hardware.PC-homebuilt .

The fact is the FTP, HTTPS and Encryptions questions were all Off Topic and you
show
multiple misunderstandings in the posts concerning...
- how Usenet works
- how the protocols in question work
- what is considered On Topic or Off Topic for any given news group
- netiquette in general

Nope.  That was in 1992.  Long September since then.

Yeah like I'm going to install this potential malware in my

for free from a reputable company?

It sounds to me, like you need a newsgroup related to cryptography.

http://en.wikipedia.org/wiki/Cryptography

A real understanding of the issues involved, requires math.
An assumption that everything is solved with brute force
searches, is wrong. Many methods of cracking encryptions, are
many times faster than brute force search. So looking at
14 digits, and assuming 10**14 test probes, is wrong. There
is always a way to speed it up, even if the recovery or
cracking method isn't that good overall.

http://en.wikipedia.org/wiki/Rainbow_tables

http://en.wikipedia.org/wiki/LM_hash

http://en.wikipedia.org/wiki/NTLM (see especially, the notes near the end)
                                     (17 years, to spot a weakness)

You'll get a much better answer in a cryptography group, assuming
you:

1) Clearly state the problem you're trying to solve. Whether it's
    safe storage of a password, or the need to encrypt a stream of
    information. State it in a way, that someone with a math background
    can pick the best algorithm or method.

2) Don't clutter your question, with assumptions on your part.
    Just state what problem you're trying to solve, and let them volunteer
    the info.

It's a pretty specialized area, and not one you're likely to get
good answers to on USENET.

HTH,
     Paul

Well I thought somebody in this group would know whether the Windows
password algorithm was like the PGP algorithm.  I guess not, since
Opchrack can crack it easily, and I've not heard that claim being made
for PGP.

That program worked on a couple of test cases, but not when I needed it.
Use these things before you make claims in ng's.
In my opinion, you are not looking for answers, just a little stirring
things up and apparently with some success.

I don't want to use Opchrack.  I want to see if others can use it to
get into my XP system.

Nope.  Try again.  But it's interesting that you apparently used
Opchrack and it failed--which does give me some level of comfort.
Feel free to share what size the password was--apparently Op* can
crack any Windows password below 14 digits (they say).

Yet, security specific newsgroups exist even cryptology newsgroups;
which is what you really want; it's specific security *heh*.. I wonder
why that is..../sarcasm.

My subject line is showing Encryption how big a to you need.. (that's
not my typo, I just copy/pasted.<G>) It's crossposting to
alt.comp.hardware,pc-homebuilt and alt.comp.anti-virus (where I'm
reading this nonsense); It is not ontopic in alt.comp.anti-virus;
Encryption isn't a virus. A virus isn't encryption. Encryption
discussions should be taken to a suitable crypto based newsgroup.

As far as answering the question, I've read several detailed answers on
it; and I thank the posters for taking the time to go into such precise
detail. Much of it being a long read, but, nice to see someone taking the
effort to explain something well. You don't seem to have a basic
understanding of cryptology tho; and I think the detailed material is
just too complicated for you to understand if you have no basic
understanding of cryptology.

I recommend you google cryptology and do some research and then the
information which has already been provided to you will make much more
sense. Your question has been answered.

It depends on how much security is desired, and how much plaintext needs
to be encrypted.
