Hi All,

A day I have dreaded for a long time has finally arrived. I must
recognized the insufficient performance of RSA encryption. It is the
only bottle-neck in moderately large software system that I am
building.

For example, making n 512 bits, e=17, d = e^-1(mod phi), and p q both
on order of 256 bits, on a typical PC, performance is on the order of
50,000-100,000 mod-exp's per second, if e is used. If d is used,
however, the performance is on the order of a few hundred operations
per second.

Given that my system does not follow the typical model assumed by, for
example, web servers running SSL, I need to maxmize end-to-end
throughput. Choosing a low exponent, might not necessarily help.

O(n) for encryption using standard big-number algorithms [binary-
method-multiply-with-reduce] is quadratic, so it would seem that if
there were a way to carefully choose both e and d to limit their
collective sizes (to reasonable extent), both sides of pipe,
encryption, decryption, would be "slow", but overall throughput would
be increased.

I am looking for AES or Twofish coding to implement cryptography in an
existing application that is written. ultimately the application will
pass a string of text that needs to be encrypted, encode-64, and
stored in a binary/text file. In addition, I need to be able to read
from a file or a string of data, decode the data, decrypt the data,
and pass the resulting string of text as a return from the function.
The resulting string will either be written to a file or passed back
as a parameter.

I already know how to read and write the file, but cryptography os new
for me. Any help will greatly appreciated and may be rewarded.

What is the Wisdom of Islaam? And how will Allaah Almighty Judge both
Muslims and Non-Muslims?

As I read the Noble Qur'ân almost everyday, I always gain more and
more respect to this Wonderful True Religion of GOD. Humans today had
so corrupted the beauty of believing in the One True Living GOD, that
they no longer became certain of which path to take. Humans today are
full of confusion and fear because many of them are apart from Islam.
That is why we are having continuous religious and territorial battles
and brutal blood shed throughout the world.

What is the Wisdom of Islam?

Islam is a very simple religion. Islam simply means submitting
yourself in peace to the One True Living GOD:

"Then Praise be to Allah, Lord of the heavens and Lord of the earth-
Lord and Cherisher of all the worlds! To Him be Glory throughout the
heavens and the earth: and He is Exalted in Power, Full of Wisdom!.
(The Noble Qur'ân, 45:36-37)"
