PMC Ciphers launches again a challenge to break a short key - this time it's as short as 32 bit. The challenge ends on February 11, 2012. The task is to crack the passphrase of a an encrypted video. The links to the video file, as well as to the C++ source code of a program that tries all possible key combinations with time, are readily available at pmc-ciphers.com for free and anonymously. The handover of the prize takes place on February 11, 2012 at 11.11 CET in the restaurant (level A1) in the Olympic Tower in Munich, Germany.
"The keyphrase consists of up to five characters "0 ..9", "a..z" und "A..Z" and one trailing character "a..d" - e.g. "0z1y2d". There exist exactly 3.724.605.612 equally possible key combinations, which corresponds with 31,79 bit. If the file was encrypted using a standard cipher like AES, the correct key could be identified with absolute certainty within an hour. Although keys with almost 32 bit length can guarantee perfect security under no circumstances, the probability is high that nobody will be able to break the key within only four weeks. Therefore would PMC Ciphers prove once again that even extremely short passwords are difficult to break for the Polymorphic High Encryption Algorithm", says C.B. Roellgen from PMC Ciphers. Mr. Roellgen adds "someone who has the computing power that is necessary to break the key and who actually identifies the key is at least that exceptional that I want to get to know him or her when the price is given. Handover of the price is thus The declared price is thus tied to appearance in person".
Later on February 11, 2012 will the keyphrase be published on the home page of PMC Ciphers (www.pmc-ciphers.com), so that everybody who is interested can easily decrypt the video and watch it.
