Can use knapsack for digital signature? is is secure?

All praise is for Allah Lord of the worlds. May Peace and blessings be
upon His trustworthy Prophet.

Dear Brothers, This topic has demanded time from me which is not
sufficient to cover it, and I hope you will be able to read it and
benefit from it as I intended for it to help the masses in
understanding this issue. Allah is the best compensator and from him
we seek reward.

· Reality

The reality is that the woman has suffered a great deal. She has been
victimized in every society, and she has grieved in every era.
Humanity has never witnessed such deprivation, sorrow, and oppression.
In other words, no one has endured more than the woman.

· History of Disgrace

From the annals of disgrace that humanity has seen is a woman being
treated like she was not even human.

The Greeks said regarding a woman: She is like a poisonous tree and
she is evil from the Satan. She may be sold like any merchandise.

The Romans said: She does not have a soul. They would torture women by
pouring boiling oil on them, or dragging them using horses.

Among the various crypto utilities I've picked up off the net, over the
years, is a simple substitution solver called "crack". It's a dictionary-
based matching program, rather than a heuristic keysearch. It's
something like George Hart's approach in Sept 94: "To Decode Short
Cryptograms".

But it's not Hart's code (or rather, it's not Jian Wang's code, who wrote
the code for Hart) - because I have that, too.

Unfortunately, there is no author information in the files I have. What
there is a file_id.diz, containing the following description:

crack lists all the possible solutions
to a simple substitution cryptogram
that are composed of words from a given
dictionary. Only letters and apostrophes
may compose the words. Upper and lower
case letters are assumed to be equivalent.

Anyone familiar with this? Any idea as to who wrote it?

I have recently seen a message from someone asking for help
in gaining access to an internet site that has been blocked
by a foreign country (not the Great FireWall of China but
the same idea).

Can anyone here tell me how to search for (or just point me to)
the software that allows you to set up an alternative domain name
or proxy to get around this type of blockade?

Six theoretically unbreakable non-scalar ciphers up and running and
not one in the hundreds of years of conventional cryptography, i.e
cryptography that uses scalar data in the form of numbers taken from
arbitrary numberlines as the encryption data source, must surely speak
for itself but no, both the industry and academia remain intractable
to overtures for change or even discussion on this matter.

There can only be one winner in any argument that is backed by
mathematical proof and to continue promoting scalar cryptography on
university websites and other so-called research groups is scientific
dishonesty. Thankfully, this kind of practice cannot last in
mathematics and it is only a matter of time before students will
realise that they are being misled.

The time to change from scalar cryptography to non-scalar cryptography
is now. Don't fight it - join it. Get behind this cryptography now.
