Geocache Description:


Proudovy sifrator.

Na vychozich souradnicich kes nehledejte, je to ale klidne misto u vody, kde muzete premyslet.



Nejprve trocha teorie.

    Pohybujeme v symetricke kryptografii, to znamena ze klic sifrovaci je stejny jako klic desifrovaci.
V proudovych sifratorech se vyuziva rychlosti blokoveho nebo proudoveho sifrovani.
Dneska jsou komunikacni a datove site chraneny na zcela jinych ruzne kombinovanych principech, ale vcem se proudovym sifratorum nevyrovnaji je jejich cena a v celku jednoduchy princip fungovani. Kdybyste nemeli zadny sifrovaci stroj, stejne muzete toho principu vyuzit k zasifrovani prenasene informace. A to se stalo :-)


V obrazku nize byly steganograficky ukryty 4 zasifrovane udaje.


Co Vas asi prekvapi je, ze nemusite hledat klic, kterym to bylo zasifrovano. Ten je tady:


    Mate 4 kryptogramy a klic, kterym byly zasifrovany. Nezbyva nez je rychle desifrovat do podoby otevreneho textu a dobre se divat. Zadny slozity sifrovaci mechanismus v tom neni, provedte jen jednoduchou operaci. Obrazky vsech kryptogramu i klice jsou samostatne v galerii.

U finalovky si zaslozene uzijte vyhled po kraji.
