passwords

问题 I'm making a forget password feature in my web app, problem is I store user's password using: Hash::make('_their_password_') Is there any way to re-hash it back or any recommended approach for this? 回答1: The point of hashing a password is that it's (supposed to be) an irreversible operation. If your database is compromised, the attacker will gain access to the hashes, but not to the passwords. That way the attacker can't log in with the users' passwords on other sites. Make a "we'll reset

问题 I have a login page which asks for a username and password. This page has a checkbox "Remember Me". Authentication is: For the username provided, convert the provided password to a hash using the salt stored with the user db record and compare the hash to the stored hash. When a user ticks the box, what should I store in their cookie so they auto login next time they visit? I was thinking that a good way was to store their username and a hashed value of their password in a cookie and to re

问题 A former developer used the PHP hash() function with the SHA256 algorithm to store password hashes. To improve the security of the system, I'd like to start using crypt() with the Blowfish algorithm (unfortunately we don't have PHP 5.5 and thus password_hash() is not available). Since SHA256 is a non-reversible hashing algorithm, is there a way to start using crypt() with the salted passwords without asking everyone to reset their password? 回答1: You should use the compatibility library then.

问题 I am using PasswordBox and I want to detect whenever the user typed there anything, if yes I need to change Button status to enabled. How can I check if user types anything in the PasswordBox ? It behaves differently from TextBox since you can't bind it to text and when user types anything raises some event. Any idea? I have tried with the code below, but I get errors: <PasswordBox> <i:Interaction.Triggers> <EventTrigger EventName="KeyDown"> <si:InvokeDataCommand Command="{Binding MyCommand}"

问题 I'm using PowerShell 5.1, Visual Studio 2017, C# , and XenServer SDK 7.1.1. Using Get-Credentials and Export-CliXml in a PowerShell program, I've saved my pool master server login credentials for the root user to an XML credentials file (xml_creds.xml) Now, I want to create and login to a session using C# (see code below). As you can see, I'm forced to convert my secure string to a plain text string to satisfy the signature for the Xen .NET API's login_with_password method. Using the API, how

问题 I'm implementing a password change feature in my web application. The old password is already saved by the browser for auto login . How can I replace it with the new password when the user login next time? I use jsp and dojo in the view part. With servlets and spring framework. 回答1: This is handled by the actual browser, you don't have access to that sort of thing with Javascript. Most browsers that store your password will also ask you to update your password if you ever successfully login

问题 Im trying to change wp_set_password pluggable function and add custom action to it: function wp_set_password( $password, $user_id ) { // Keep original WP code global $wpdb; $hash = wp_hash_password( $password ); $wpdb->update( $wpdb->users, array( 'user_pass' => $hash, 'user_activation_key' => '', ), array( 'ID' => $user_id ) ); wp_cache_delete( $user_id, 'users' ); // and now add your own $custom_hash = password_hash( $password, PASSWORD_DEFAULT ); update_user_meta($user_id, 'user_pass2',

问题 We have a Perl script that uses the terminal to read a password. This script does not work on Windows as the terminal is not available. We did some research and found that ReadKey/Readline is an alternative for this. However, this package is not part of our default Perl install. Is there a way to read a password in Perl without using the terminal or ReadKey/Readline? 回答1: If you are looking for a way of getting the password without echoing in the terminal, try this: use Term::ReadKey; print

问题 I am making a password reset form, which contains two fields: password1 and password2. The user enters their new password and then re-types their new password again. I'm not sure how to make a validation rule that will compare the two values from the fields and see if they're the same. 回答1: if you are using Auth component then you need to hash the second password in the controller, because the password will be automatically hashed. To compare 2 fields, you need to write a custom validation

问题 I have a JavaScript page that makes an Ajax call like the code below. The PHP page is inside a corporate intranet and requires authentication in the domain (basic auth is disallowed). I collect the username (u) and password (p) from input fields using jQuery. var u = $('#user').val(); var p = $('#pass').val(); $.ajax({ url: "http://mydomain/mypage.php", username: u, password: p, error: function () { } }).done(function(html) { //Do Stuff }); The solution works very well...except when the user
