The phrase you gave, "frankly, my dear, I don't give a damn" meets most definitions of complexity. I has upper and lower case letters and special characters.

And that a 15 character or longer password can be a real phrase and it will be a secure password. I can see why a long password that consists of a real phrase - such as "frankly, my dear, I don't give a damn" - would be just as secure as an equally long complex password, in terms of protection against a brute force attack. I don't know much about password cracking programs but am surprised that, while they would be working on a brute force attack, they wouldn't be able to try a lot of commonly-used phrases at the same time. If some password cracking programs can use a dictionary attack, couldn't there also be something called a passphrase attack? Would it be difficult for a password cracker to digitize Bartlett's Book of Quotations and include that in an attack on a password? ------------------------------------------------------------------------ --- This list is sponsored by: SensePost Hacking, like any art, will take years of dedicated study and practice to master.
