I calculated the other number. It is not expected as answer and I don't see anything interesting when interpreting the number in other ways. Am I missing the punchline?

Hi Tron,

you're right. It's my challange. I messed up the challange by printing the cleartext instead of the cipher text. I've have send Adum an update right now (I also altered the cleartext). Maybe the 6 solvers should try again after fix has been applied.

Sorry for the inconvinience guys!

The new encoded message is larger than the modulus. This does not make much sense.

Hi Tron,

ok, the modulus is

18177463113985279014593768153541854004936176165294524057336890660730144311208729

Begginers fault again: I haven't completely updated the challange text, only the source code printing out the numbers. But you seem to be on the right track Tron ,)

I recommend to let one's challenge be beta-tested by (an)other person(s) before submitting it.

Hmmm.... I think that now Alice nor Charly can decrypt the message. The number must be smaller than the modulus as Tron said!

efe, you have to use this number as modulus (adum hasn't changed that yet):
13927286537254031626323670117308341421825250505042934290710960886577880641606495

but bloody hell, it's taking some time to extract that information from this number
60 digits was easy, but 80 it's not so simple with my method (perhaps i'm not using the best way to crack this)

Ok, now I solved it with the new modulus Smile

Solved too Very Happy
This one took some time to manipulate the modulus number.

No this is the cipher text. Please use the modulus i have posted here.

Whoops, you're right !
Have you already contacted adum to correct the modulus too?

Yes, I wrote adum a mail 4 hours ago ... Probably this will soon be corrected.

beta testing challenges is not a bad idea, for some that might be malformed...

I would suggest just doing a dry run from scratch at least once to check you haven't gone astray somewhere
