  Islam and Honesty

Islam and Honesty

Islam orders the Muslim to be honest to himself and others. This order
repeatedly comes in the Noble Qur'an and the sayings of Prophet
Muhammad (SAWS). Islam orders the Muslim to tell the truth even if it
is against the teller's interest. Orders him not to cheat or deceive
other people. A Muslim is ordered by Allah to be honest in his words
and deeds, privately and publicly alike.

Implication of Honesty

Honesty in words implies telling the truth in all cases and under all
conditions. Honesty also implies fulfilling the promise, whether
written or given orally, in text and spirit. Honesty also implies
giving the right advice to the one who asks for it.

Honesty also implies doing one's work as sincerely and as perfectly as
possible. Honesty also implies carrying out duties as fully as
possible whether the person is supervised or not. Honesty means giving
every person his due rights without his asking for these rights.

  Why Hamada is posting in the NG?         


Author: Basti05b

Dear Newsgroup:

Let us debate, what is Hamada’s objective of posting religious and
other similar issues in American open media like sci. math and several
other newsgroups?

I know that newsgroups are global, but I am only interested in its
impact on American issues.

What are the intentions of Dr. Tariq Al Suwaidan (here is written
Tareq)?

http://en.wikipedia.org/wiki/Tareq_Al-Suwaidan

who is supporting and masterminding Hamada and his mission in America.

While I believe Hamada possibly is an Islamic scholar, why they have
selected him as a tool to deceive the American public ?(what is his
hidden agenda?)

We also need professional scholars in America to dig into the verses
of Dr. Tariq Al Suwaidan. As explained here:

http://mathforum.org/kb/thread.jspa?threadID=1742408&tstart=15

The American higher education is in such a crisis.

These issues are all connected!

  "ASCII Direct" puts the Kibosh on Numerical Analysis         


Author: AdaCrypt
Date: May 21, 2008 03:23

Direct mapping of plaintext to cipher-text using the alphanumeric
characters set of ASCII directly on their own and studiously eschewing
the decimal number representation of these characters as a primary
transformation of the plaintext that is so often used as a preliminary
step in current cryptography, draws the teeth of even the most
prodigious numerical cryptanalysis of the eventual cipher-text.
Numerical analysis then becomes useless as a tool for cryptanalysis of
the ensuing cipher-text - it simply cannot work on alphanumeric data.
That same goes also for lexical attack and implicit arithmetical
attacks on alphanumeric cipher-text.

The algorithm for this direct mapping is provided by the well-known
ā€œVigenere squareā€ in an application to a modern one-time pad such
that,

(Plaintext + Key) Mod 95 = Cipher-text Mod 95

This is the equation of a ā€œVigenere squareā€ that is projected now on
to an OTP.

  Two factor authentication in PeaZip 2.1         


Author: giorgio.tani.software
Date: May 21, 2008 01:58

PeaZip is an Open Source file and archive manager for Windows and
Linux.
http://peazip.sourceforge.net/

It supports various types of archive with encryption features (7Z,
ARC, ZIP) and in 2.1 release I introduced the possibility of using
keyfiles for two factor authentication in those formats, aiming to
enhancing security against dictionary and some forms of social
engineering attacks.

Keyfiles are hashed with SHA256 and the Base64-encoded (RFC 4648) hash
is pre-pended to the password.

This allows to not break compatibility with other archive manager
applications (or command line utilities) supporting only passwords-
based encryption, since archives encrypted in that way can be opened
simply calculating the hash and prepending it to the password.
