Otherwise it would defeat the purpose of encryption. While it might seem trivial, the number of combinations is staggering. 52 letters (upper + lower case) and punctuation plus number (average of another 50) means you have 102^11 which is a Very Large number.Duane Nickullhttps://www.blogger.com/profile/08767498160563891543noreply@blogger.comtag:blogger.com,1999:blog-17460203.post-56115935917724742782009-11-03T15:01:19.339-08:002009-11-03T15:01:19.339-08:00Suppose your used an encryption program that used ...Suppose your used an encryption program that used 128 bit AES to encrypt files.<br /><br />Then you forget the password used as the key.

A brute force cracker, will, given time crack anything because it does not need a basis for cracking. If the password is five characters or less, a brute force crack would take less than <B>one year</B> on the average PC.<BR/><BR/>However that is assuming a cracker with a great deal of money would limit themselves to 20 permutations per second and would use an average PC. <BR/><BR/>A brute force cracker simply inputs a specific number of different letters every 1/20 of a second and tests passwords individually, one at a time, changing one letter each time.<BR/><BR/>The only time a brute force crack will not work is when one mixes letters, numbers and symbols. Such a contingency would yield an innumerable amount of testable permutations.<BR/><BR/>That is assuming one cannot use multiple PCs to test different permutations. In fact 20 computers working together with simple duel cores would be able to test 400 predetermined permutations per second. That means that file that took a year now takes <B>two weeks</B>.<BR/><BR/>Or if you work for the government you could afford some Itanium CPUs that would cut that time in half, down to <B>one week</B>.<BR/><BR/>But I'm afraid the NSA has more than 20 computers. In fact the Tordella Supercomputer Building has several floors of interlinked computers dedicated to brute force cracking, the equivalent of well over 1000 computers. using this system ones nice AES encryption can be broken in the <B>"minutes" to "hours"</B> range.<BR/><BR/>That is of course assuming the NSA and America own the most powerful computer on the planet. But one should note that that may not be true. <BR/><BR/>In short, that rar,pdf or 7z file you thought was secure really isn't, no matter how powerful your encryption is. The weakness is not in the encryption, but in the amount of tries it takes to guess most passwords.<BR/><BR/><B>AES is only strong if the password that protects it, is strong as well. A complex number of letters, numbers and symbols is the best way to secure your AES encrypted document ,Also note that by starting your password with a "Z" you make a crackers job very difficult because "A" is usually the starting permutation.</B><BR/><BR/>Some simple thoughts from a cracker ;)<BR/><>smootch<> anonAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-17460203.post-79159527452908782352006-08-25T08:46:00.000-07:002006-08-25T08:46:00.000-07:00That may be true depending upon the architecture a...That may be true depending upon the architecture and what kind of algorythmn one could design. Since no one is in danger of marketing one any time soon, I think that the core goals of the AES algorithm are being met.
