passwords

So I am trying to write a program that asks for you to create a password. I have a block of code that checks to see if the string entered by the user contains a symbol. I have the code set to exit the loop when the boolean value 'validPassword' equals true. string pleaseenterapassword = "Create a password:"; bool validPassword = false; Console.WriteLine(pleaseenterapassword); // Writes to the screen "Create a password:" string password = Console.ReadLine(); //Sets the text entered in the Console into the string 'password' bool containsAtLeastOneSymbol = password.Any(char.IsSymbol); if

I was trying to use Android Password expiration feature using DeviceAdmin . When I call setPasswordExpirationTimeout() API , it only sends a notification and doesn't actually force the user to change the password. It only sends a notification after timeout: V/DevicePolicyManagerService( 662): Sending password expiration notifications for action com.android.server.ACTION_EXPIRED_PASSWORD_NOTIFICATION You have to get the callback in DeviceAdminReceiver in onPasswordExpired() to force user to change password. Any specific reason it's been implemented this way (or is it just to give flexibility to

All, Our server is running Java 1.5 and I am having difficulty trying to mask user input from the command line. I am executing a jar file (java -jar my.jar) and am working through command line prompts via printlns. I cannot use Java Console. Thanks On a Unix system? You could try running the system program stty with argument -echo before reading the program and the program stty echo afterwards. ProcessBuilder pb = new ProcessBuilder("stty", "-echo"); pb.start().waitFor(); // Read the password here pb = new ProcessBuilder("stty", "echo"); pb.start().waitFor(); Note that I have not tried this!

I am designing a C# application in which I need to store users' login information, including their passwords, in a database table. I was wondering what's a decent way of doing this. I know it is a terrible idea to store passwords as clear text. I was thinking of encrypting the passwords and then storing them. After that, every time the users enter their passwords, I can encrypt their input and compare that encrypted input with the one already in the database. My plan is to use a good has function for the encryption... I think a common tactic is to make a hash of the password using something

This question already has answers here : Closed 6 years ago . Possible Duplicate: Is it possible to decrypt md5 hashes? In my website, I'm using md5 encryption for the password. So it's saving in the encrypted form in the database. For doing the password recovery, how can I decrypt the encrypted password ?? Please Help :) As others described quite well, you cannot easily 'decrypt' an MD5 hash. I guess the best way to do your password recovery is like this: A user can request password recovery by providing his email address (it should be unique so users can be identified by email address). an

I wonder whether someone could help me please. I've been doing quite a bit of research on the 'Password Reset' process and from one of the tutorials I found, I've been able to put the following code together which provides this functionality. Forgot Password <?php // Connect to MySQL $c = mysql_connect("host", "user", "password"); mysql_select_db("database", $c); // Was the form submitted? if ($_POST["ForgotPasswordForm"]) { // Harvest submitted e-mail address $emailaddress = mysql_real_escape_string($_POST["emailaddress"]); // Check to see if a user exists with this e-mail $userExists = mysql
