Help password protecting a desktop application

Hey guys I'm creating an application that I need to password protect. I've already created a JFrame with components and action listeners where a user can enter a password (twice to make sure they match) and a username. When my application begins the first thing the user sees are these three fields with instructions prompting them to register. Is there a way to encrypt this information and store it securely? Does anyone have any tips as to good practices when creating a secure application?

what's the best way secure
information in an application. Depends on the information! (and application and .....)
Why would you store the password in a
database? Why not?
On a serious note, where else would you like to store passwords? I suppose a text file is an option - although (imho) its only suitable for a small data structure (small number users).
What are the benefits? What are the benefits of using database over text files?
Ease of use, would be my first argument!
Performance*
*this may be dependent on size of the data structure. Some may argue that a text file offers better performance for small structures - I'm don't know.

Is there a way to password protect a Desktop Folder in Yosemite

I have an IMAC running Yosemite 10.10.2. I would like to password protect a Desktop Folder. Is there a way to do this?

You need to find a third-party utility that does that. You should find one at macupdate.com or at the App Store. In order to use OS X you would need to create an encrypted disc image using Disk Utility, then store your folder in the disc image. That way only you can mount the disc image and access the data.

Urgent...help password protection...

hello...
Anyone out there know the coding for password protection using application....for example the user will type in the username and password and a statement will come out to validate the password...
Thanks a lot..

Hi! A simple way of approaching the matter is to read the user name and the password from the GUI, then get the password from the database corresponding to the username and compare the two. You'll need to use JDBC for the latter.
Here are a couple of points to remember. You may want to determine if your password scheme is case-sensitive or not. Secondly, you may want to use the setEchoChar() method (if you're using a java.awt.TextField object for getting the password from the user) so that the password is not echoed to the screen while the user is typing it.
Hope this helps! Feel free to ask if something's not too clear.
Cheers!

smercurio_fc, see now you are following me around.... (Beat you by a few minutes on the other tread).
I think the question is not about passwording the diagram, but a UI choice where certain parts are only shown after entering a password. For example, there might be data for the operator and there might be extra data or controls only of interest to the engineer. The display should change depending on the privileges of the current user.

No. You can lock your main screen, but thats about it.

Hi mate take a rectangle and fill it to scene width !
use fill gradient and bind it to your main scene.width
for example :
Rectangle {
fill: color.Blue
stroke: LinearGradient {
startX: 125.0, startY: 0.0, endX: 225.0, endY: 0.0
proportional: false
stops: [
Stop { offset: 0.0 color: Color.web("#1F6592") }
Stop { offset: 1.0 color: Color.web("#80CAFA") }
use appropriate start and offset then bind it to scene width and height.
width : bind scene.width;
height : bind scene.height ;

How would I password protect the MAIL application?

I have never used passwords - but what I wanted to do was put a password (somehow) on the MAIL application so that no one can use it but me - in other words, when I click the application, it asks for a password before turning on. I want this to happen even when I am in my own (admin) account - is this possible?

This is not possible; you'd have to setup different accounts for each user, and then limit their access to various applications and/or files.

Urgent Help: Password Protect Files in WebLogic

I am a newbie in Java and have a very urgent and serious problem which I hope to
get some advice from the experts =}. As u know that by keying in the exact url
of a document that resides on the server, any1 will be able to download the file
without logging in at all.
For my case, I already have secruity checking in place e.g. "/customer/check.jsp"
to check if the user e.g. ERIC exists in the database before allowing him to login
to access the files under that specific directory e.g. "/customer/docs/". If someone
[not ERIC] tried to access other files like jsps/htmls/other directories without
logging, the person will be thrown back to the login.jsp e.g. "/customer/login.jsp".
This is ok. But this does not solve the above stated problem. If the person enters
the URL e.g. "http://www.abc.com/customer/docs/mytest.pdf", he can retrieve that
particular file without logging in.
The only way to block it is via the "URLacl" which will prompts for login if the
URL is entered directly.
The only problem is that my customers will definitely complain if they have to
login at the login.jsp e.g. "/customer/login.jsp" and when they click to download
the file e.g. "/customer/docs/mytest.pdf". Any ideas I can pass the login info
around without logging twice or how can I protect/restrict the entire directory
"/customer/docs/" by using jsp?
Any help is greatly appreciated!!!
thanks alot in advance....

Hi,
I think you want to create a WebApplication.
Please have a look at:
http://e-docs.bea.com/wls/docs70/webapp/basics.html#108532
In this WebApplication some subdirectories are not allowed to everyone to enter.
For this the user has to be authenticated.
This can be done through configuring the WebApplication.
http://e-docs.bea.com/wls/docs70/webapp/security.html#100607
A sample can be found in the examples directory which comes with
WLS: examples\webapp\security WebApp.

Is there a way to password protect my email application on my iMac ?

I don't mind having guests using my iMac for accessing the internet, but I don't want them snooping through my emails. How can I secure the email app?

If you re operating with only one admin account, go o System Preferences, Users and Groups and create a new standard user account. You will have to first create a password for your present account because it will become necessary to login to specific accounts to use the iMac.

Password protecting mail application.

Hello,
I would like to know if i can password protect my mail application, just the way outlook express can be done.I would not like to create a different user
acccount for doing the same.
Thanks in advance

You could make Mail ask for a password before fetching new mail or sending mail by altering your keychain preferences. Either prevent Mail from storing your email password in the keychain or let it do that but make sure that your keychain has a different password than your user account, is not set to automatically unlock on login and locks after a very short idle time.
If you have an imap account and leave your messages on the server, this effectively prevents access to your mail without a password. If you use pop and/or download messages to you local folders, though, anything already downloaded will be accessible without a password.

Password protect Mail on iPad

Just got a brand new iPad. Is there a way natively or via another app to password protect the Mail application? I'd love to be able to let others use the iPad for internet browsing or games, but with Mail if you click it you can get right into all my email accounts with all my data. Would love to be able to have extra security on top of the Mail program to even get it to open up.
Many thanks in advance for the help.

Exactly, parental control, but its just not as developed of a feature as I would have hoped for. Seems like there's lot of questions on the boards dating back for years on this where most people just gave up. But that's one heck of a business model, Apple wanting me to buy a $800 device so a little kid can play an educational game for maybe an hour or two a week
Sounds like Kyle might have an idea of something.

Share Excel File that is password protected

Hello all
I have published a workbook in our shared area at work. It's massive and also has another workbook linked to it.
Both are password protected so are only available for viewing. But tons of people need to see them particularly the source file which is no problem because they can't change anything so can choose 'read only'.
However the problem is when I need to go in there to make a couple of alteration, I have to wait until they close it or of course as is typical, they will leave their desk and forget to close it!!
I haven't used the sharing workbook option although I've tried it and shown one of our departments to use it basically.
I was wondering if this would be possible on a file that is password protected and is locked on every sheet.
That way I can just go in when I need to even if someone's in there.
This is an extremely important file that
can not go wrong. (I do have a backup)
What are your views on this option and what is the best way to go about it?
Thanks

Hi,
Would you like to tell me which Excel version are you using? According to your description, I recommend we try the two methods:
Method 1:
Excel has a feature "Protected the sheet", we can assign the different password to each sheet.
For more detail information, please refer to the following link:
http://office.microsoft.com/en-gb/excel-help/password-protect-worksheet-or-workbook-elements-HP010078580.aspx
Method 2:
Share the Excel workbook, and assign the edit range/permission to users. We can allow specific users to edit ranges in Excel. Here is the steps:
Click 'Review', 'Allow Users to Edit Ranges','New'. In 'Title', enter the name. In 'Refers to cells', enter an equal sign (=) and enter the reference. In 'Range password', enter password. Click 'Permissions'. Click 'Add'. Enter the name. Click 'Protect Sheet',
enter password. Click 'OK'.
