nsane.forums Posted June 10, 2012 Share Posted June 10, 2012 Analysis: "Strong" isn't a detailed password-rating; go for a quintillions possible combos, add a symbol. Security breaches of mind-numbing size like those at LinkedIn and eHarmony.com set crypto- and security geeks to chattering about weak passwords and lazy users and the importance of non-alphanumeric characters to security. And insisting on a particular number of characters in a password is just pointless security-fetish control freakishness, right? Nope. The number and type of characters make a big difference. How big? Adding a symbol eliminates the possibility of a straight dictionary attack (using, literally, words from a dictionary. Adding a symbol, especially an unusual one, makes it much harder to crack even using rainbow tables (collections of alphanumeric combinations, only some of which include symbols). How big a difference to length and character make? Look below and pick which password-cracking jobs you'd want to take on if you were a computer. The examples come from the Interactive Brute Force Password Search Space Calculator: at GRC.com, the love child of from former InfoWorld columnist and freeware contributor Steve Gibson How long would it take to crack my password: (Includes letters and numbers, no upper- or lower-case and no symbols) Six Characters: 2.25 Billion Possible CombinationsCracking online using web app hitting a target site with one thousand guesses per second: 3.7 weeks.Cracking offline using high-powered servers or desktops (one hundred billion guesses/second): 0.0224 secondsCracking offline, using massively parallel multiprocessing clusters or grid (one hundred trillion guesses per second: 0.0000224 seconds Ten Characters: 3.76 Quadrillion Possible CombinationsCracking online using web app hitting a target site with one thousand guesses per second: 3.7 weeks.Cracking offline using high-powered servers or desktops (one hundred billion guesses/second): 10.45 hoursCracking offline, using massively parallel multiprocessing clusters or grid (one hundred trillion guesses per second: 37.61 seconds. Add a symbol, make the crack several orders of magnitude more difficult: Six Characters: 7.6 trillion Possible CombinationsCracking online using web app hitting a target site with one thousand guesses per second: 2.4 centuries.Cracking offline using high-powered servers or desktops (one hundred billion guesses/second): 1.26 minutesCracking offline, using massively parallel multiprocessing clusters or grid (one hundred trillion guesses per second: 0.0756 seconds Ten Characters: Possible Combinations: 171.3 Xextillion (171,269,557,687,901,638,419; 1.71 x 1020)Cracking online using web app hitting a target site with one thousand guesses per second: 54.46 million centuries.Cracking offline using high-powered servers or desktops (one hundred billion guesses/second) 54.46 yearsCracking offline, using massively parallel multiprocessing clusters or grid (one hundred trillion guesses per second: 2.83 weeks. Take Steve's advice: go for ten characters, then add a symbol. View: Original Article Link to comment Share on other sites More sharing options...
