passwords

How can I protect files and directories with a password in C#? If you need to protect files and folders you have several options: Control the operating system level permissions with ACLs (Access Control Lists) so only the authorized users on the computer have access to those objects. This will not create a new password for the file, but will just deny access to every user that is not authorized. The downside is that this needs to be done on a machine (or Active Directory domain) level. So if you copy the file to another machine, the protection is no longer active. You can use a compression

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 be duplicates and ultimately need to be discarded. I am attempting to do this on a device which has a

I stored salt and hash values of password during user registration... But during their login i then salt and hash the password given by the user, what happens is a new salt and a new hash is generated.... string password = collection["Password"]; reg.PasswordSalt = CreateSalt(6); reg.PasswordHash = CreatePasswordHash(password, reg.PasswordSalt); These statements are in both registration and login.... salt and hash during registration was eVSJE84W and 18DE22FED8C378DB7716B0E4B6C0BA54167315A2 During login it was 4YDIeARH and 12E3C1F4F4CFE04EA973D7C65A09A78E2D80AAC7 ..... Any suggestion....

I'm developing an app that requires multiple passwords to access varying data areas. For example, a group of people could set up a chat that requires password authentication to view. Here's how I'm considering doing it: I have my keyword, let's say hypothetically: Banana When the user enters their password, I use RNCryptor to encrypt Banana using their entered key, and store that encrypted string to the server. Later, when someone tries to enter a password, I take the hashed value from the server and try to decrypt it using the password they entered as a key. If the decrypted value equals

I've encountered a problem where I had to load more than 200 new users into my django app and right away send them a password reset email. This had to happen only once, done only by me and run quietly on backend. Surfing the internet brought me only to one more or less right answer: Trigger password reset email in django without browser? . The only problem was is that this post was about 4 years old and of course when I tried the solution, it didn't work... Two most valuable points from the link I mentioned: 1) In more recent version of Django we need to call form.is_valid() 2) Sending of

Creating a Client Login area. I have my log in form in a clientLogin.html: <form name="ClientLogin" method="post" action="login.php"> <br> <p> <label for='Username'>Username</label> <br> <input type="text" name="username" /> </p> <p> <label for='Password'>Password</label> <br> <input type="password" name="password" /> </p> <br> <input type="submit" value="Submit" /> </form> If the username & password combination are incorrect I want to redirect to this page adding a message saying "incorrect username/ password please try again". This is the code from login.php: <?php //Connect to the database

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 cookie. However, I'm not sure how to do that with the php function. Here's the whole function: function

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 java.util.*; import java.lang.String; import java.lang.Character; /** * @author CD * 12/2/2012 * This
