password-storage

I'm using Struts 2, my problem is that I don't want to update all my object properties because I got some sensitive data. Here is my code example public class person { private name; private email; private password; } In my form for example I display the name and email for update ,so when I update my person properties after submission ,the password property of the person gets the value null,but when I put the property password in the <s:hidden> tag in the form the update works fine. How to make Struts 2 remember the value of the password without using the hidden tag in the form ? If you need to

According to PHP's doc, bcrypt salt are made of "$2a$", a two digit cost parameter, "$", and 22 digits from the alphabet "./0-9A-Za-z" So, if i use the crypt() function to hash my passwords, the resulting output include the first 7 chars ($2a$10$, if 10 is the cost parameter) as a part of the salt - and, according to all examples i was able to find across the internet, this complete output is written to db. I'm wondering what's the point in storing those first characters with the rest of the salt and the encrypted data. Their meaning is fully clear to me, but i can't really understand why such

I'm using Sequelize to do a DB find for a user record, and I want the default behavior of the model to not return the password field for that record. The password field is a hash but I still don't want to return it. I have several options that will work, but none seems particularly good: Create a custom class method findWithoutPassword for the User model and within that method do a User.find with the attributes set as shown in the Sequelize docs Do a normal User.find and filter the results in the controller (not preferred) Use some other library to strip off unwanted attributes Is there a

We store all our application and db passwords in plain text in source control. We do this as our build/deploy process generates required configuration files and also does actual deploys that require these passwords (ie: running sql against a database requires you logon to the db using valid credentials). Has anyone had a similar need where you were able to implement this type of functionality while not storing the passwords in plain text? If your plan is to store all the code and configuration information to run a production system directly from version control, and without human intervention,

What would be the recommended way for storing passwords in a Java desktop application? I want the user to have the ability to enter the credencials only once and not be prompted again. On personal projects I've been using the Preferences API, but I'm assuming this is no different than storing it in plain text (security wise). Many thanks EDIT: Many thanks for your suggestions. There seems to be some confusion, no doubt because I might have not made the question very clear... I'll give an hypotetical scenario: Say I'm creating a simple front-end for a remote database which creates a connection

Probably a very newbie question but, Ive been reading around and have found some difficulty in understanding the creation and storage of passwords. From what i've read md5/hash passwords are the best ways to store them in a database. However, how would I go about creating those passwords in the first place? So say I have a login page with user bob, and password bob123 - how will I 1. get bobs password into the database to begin with (hashed) 2. how do I retrive and confirm the hashed password? Thanks Edit 2017/11/09: Be sure to take a look at the answer from O Jones. First off MD5 isn't the
