show me the interpretation thereof, shall be clothed with scarlet, and have a
chain of gold about his neck, and shall be the third ruler in the kingdom.
then came in all the king's wise men; but they could not read the writing, nor

greatly troubled, and his countenance was changed in him, and his lords were

L'Albatros
Charles Baudelaire (Les fleurs du mal)
======================================
Souvent pour s'amuser les hommes d'equipage
prennent des albatros vastes oiseaux des mers
qui suivent indolents compagnons de voyage
le navire glissant sur les gouffres amers.
[ Le
A peine [s]le sont ils deposes sur les planches
que ces rois de l'azur maladroits et honteux
laissent piteusement leurs grandes ailes blanches
comme des avirons trainer a cote d'eux.
Ce voyageur aile comme il est gauche et veule
lui naguere si beau, qu'il est comique et laid.
L'[u]an agace son bec avec un brûle gueule,
l'autre mime en boitant l'infirme qui volait
le poete est semblable au prince des nuees
qui hante la tempète et se rit de l'archer
[baudelaire]
exile sur le sol au milieu des huées.
[ Le mot pour [l']étage quatre est Trajan. ]
Ses ailes de géant l'empêchent de marcher.
mot pour [l']étage quatre est Trajan. ]

Stage 6 - Solution
This stage is number six and it is a playfair cipher. The following
stage is number seven within the context of this competition and it is
encrypted according to an ADFGVX type cipher. When you attempt to
cryptanalyse stage seven you will see that it is more complicated than
a straight forward ADFGVX cipher. Unfortunately I can not give you
any more clues.
In terms of this stage the shibboleth that you should take note of
is molybdenum.
You will probably have noticed by now that each stage is in a
different cipher and is usually in an appropriate language. So the
Vigenere stage was in French and this playfair stage is in English.
If the pattern persists then the next stage will be in German. But
does the pattern persist?

Pierre de Fermat wurde am 20.August 1601 in der sudwestfranzoischen
Stadt Beaumont de Lomagne geboren. Der Vater Dominique Fermat war ein
wohlhabender Lederhandler und so kam Fermat in den Genuss einer einer
vorzuglichen Schulbildung im Franziskanerkloster Grandselve der sich
ein Studium an der Universitat von Toulouse anschloss. Ob sich Fermat
schon als junger Mann in der Mathematik besonders hervorgetan hat ist

Excerpt from Othello, Act 5, scene 2 (William Shakespeare)
Armstrong ====================================
Stage 9 - Cleartext
O! cursed, cursed slave. Whip me, ye devils,
From the possession of this heavenly sight!
Blow me about in winds! roast me in sulphur!
Wash me in steep-down gulfs of liquid fire!
O Desdemona! Desdemona! dead!
Only one more phase to go. Your token for this one is "Armstrong".
The final hurdle contains two ciphertexts. The longer one is encrypted with triple-DES in electronic code
book mode. It uses a 128-bit EDE key. The RSA public key cryptosystem has been used to encipher the tripleDES key; this forms the shorter ciphertext. The public exponent is 3735928559 in decimal and the public
modulus is the following 155-digit decimal integer:
10742 78829 12665 65907 17841 12799 42116 61266 39217 94753 29458
88778 17210 35546 41509 80121 87903 38329 26235 28109 07506 72083
50494 19964 33143 42555 83344 01855 80898 94268 92463.
Your task is to decipher the longer message and so discover the final code word. How you do this is up to you,
but it will almost certainly be much, much easier to break the RSA ciphertext by factoring the public modulus
than by any other approach.
Good luck!

Stage 10 - Conclusions
RSA depends on factoring being computationally difficult
We factored a 155-digit (512-bit) number into two primes
Usually, 1024 bits is minimum length today
Adding one bit doubles the size of the composite but it does
NOT double the effort for factoring
Assuming Moores law, factoring a 1024 bit composite can be
done with the same effort forty years from now.
