passwords

问题 I'd like to use form validation to require a password that has BOTH alpha and numeric characters. Here's what I've come up with so far: $this->form_validation->set_rules('password', 'Password', 'required|matches[passconf]|min_length[8]|alpha_numeric'); The issue is that "alpha_numeric" requires that the password only contain letters or numbers, it doesn't require both. Going for the stronger password option here. 回答1: You could set up a callback in your controller: public function password

问题 I was doing a little research or googling for different methods of handling password hashing and salting and came across this interesting link: http://phix.me/salt/ Now, essentially what this proposes is the creation of two user functions, one for hashing and one for checking the hash. The salt is pseudo random but is in actual fact based upon the password (strikes me as bad?). The hashing function also pseudo randomly "sprinkles" the salt amongst the hash string. The hash checking function

问题 In Sql Server 2005 what data type should be used to store passwords hashed by SHA-256 algorithm? The data is hashed by the application and passed to the database 回答1: I prefer to convert the hash-Code to an Hex-String in this case a varchar(64) will do the trick or an varchar (66) if you like a " 0x "-prefix. In this way it is much easier to compare manually or (re)set values you have to copy/paste from other places. e.g you lost your admin-PW and want to reset it via SQL... 回答2: The "Hash"

问题 Context: I am attempting to combine a large amount of separate password list text files into a single file for use in dictionary based password cracking. Each text file is line delimited (a single password per line) and there are 82 separate files at the moment. Most (66) files are in the 1-100Mb filesize range, 12 are 100-700Mb, 3 are 2Gb, and 1 (the most problematic) is 11.2Gb. In total I estimate 1.75 billion non-unique passwords need processing; of these I estimate ~450 million (%25) will

问题 I'm using wordpress for a specific client because of their need to edit content themselves. With this, I'm using their page password protection, per client's request. The problem is, it seems that the cookie being set never times out. So, once the client enters the password, nobody ever has to enter the password again through the same browser on the same machine. This leaves it wide open for anybody to walk up to and enter. So, I assume the best way to address this is to set a timeout on the

问题 Problem Description: Some Websites impose certain rules for passwords. Write a method that checks whether a string is a valid password. Suppose the password rule is as follows: A password must have at least eight characters. A password consists of only letters and digits. A password must contain at least two digits. Write a program that prompts the user to enter a password and displays "valid password" if the rule is followed or "invalid password" otherwise. This is what I have so far: import
