密码黑客会采取多种不同的形式,但要明白关键的一件事是,它通常不是恶魔般的狡猾,而是蛮力的使用。
This is where the length of your password makes an almost unbelievable difference. For a hacker with the computing power to make 1,000 guesses per second, a five-letter, purely random, all-lower-case password, such as "fpqzy", would take three and three-quarter hours to crack. Increase the number of letters to 20, though, and the cracking time increases, just a little bit: it's 6.5 thousand trillion centuries.
你密码的长度可以产生几乎令人难以置信的差异。对于黑客的计算能力,每秒1000次猜测, 5个字母、完全随机、全小写的密码,如“fpqzy”,只要花费3小时45分钟来破解。把字母数增加到20,只是一点点,但破解的时间增加:这将是6500万亿个世纪。
Then there's the question of predictability. Nobody thinks up passwords by combining truly random sequences of letters and numbers; instead they follow rules, like using real words and replacing the letter O with a zero, or using first names followed by a year. Hackers know this, so their software can incorporate these rules when generating guesses, vastly reducing the time it takes to hit on a correct one. If you think you've got a clever system for coming up with passwords, the chances are that hackers are already familiar with it.
这样就有可预测性的问题。没有人想出密码是由字母和数字真正随机组合的序列;相反,他们遵守规则,像使用真正的单词和用“zero”替换字母“O”,或在名字后面加上年份。黑客们知道这一点,所以他们的软件在进行猜测时可以兼容这些规则,大大减少了猜中正确答案所花费的时间。如果你认为你已经有了一个想出密码的聪明方法,很有可能黑客们早已熟悉它了。
