Stage 4 - Automated SolutionL'AlbatrosCharles Baudelaire (Les fleurs du mal)======================================Souvent pour s'amuser les hommes d'equipageprennent des albatros vastes oiseaux des mersqui suivent indolents compagnons de voyagele navire glissant sur les gouffres amers.

A peine [s]le sont ils deposes sur les planches que ces rois de l'azur maladroits et honteuxlaissent piteusement leurs grandes ailes blanchescomme des avirons trainer a cote d'eux.

Ce voyageur aile comme il est gauche et veulelui 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 nueesqui 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.

This stage is number six and it is a playfair cipher. The followingstage is number seven within the context of this competition and it isencrypted according to an ADFGVX type cipher. When you attempt tocryptanalyse stage seven you will see that it is more complicated thana straight forward ADFGVX cipher. Unfortunately I can not give youany more clues. In terms of this stage the shibboleth that you should take note ofis molybdenum. You will probably have noticed by now that each stage is in adifferent cipher and is usually in an appropriate language. So theVigenere stage was in French and this playfair stage is in English.If the pattern persists then the next stage will be in German. Butdoes the pattern persist?

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 triple-DES 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 2945888778 17210 35546 41509 80121 87903 38329 26235 28109 07506 7208350494 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!

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

RSA depends on factoring being computationally difficult

Assuming Moores law, factoring a 1024 bit composite can be done with the same effort forty years from now.
