How to read password in scrambled format

[herurmath saraswathi]

Hi all, In one of my application , i have to read password in scrambled format, so that no body can see that password in the script. When we run the script, it accept the correct password...

[Robert Hill]

Is there a question?

you could add a keyListener to the textfield, and as they hit any

charater keys and Digit keys, diplay '*', but update a private String,

so you dont loose the password..

Or use JPasswordField...

But he said something about a "script", so it's not clear if this is even Java, let alone a Java GUI application. Let's see if he can clear this up for us.

k, I saw the script too, but I thought maybe he was just refering to the
textfield display.

I could be wrong but I think what he means is there's a file on the harddrive with the password saved in it, but he doesn't want that password to be saved in clear text. So if someone sat down at the comp. they wouldn't be able to read the password when looking at the file.

If that's the case, you want to use encryption (probably just hash the password). Look at bouncycastle for a VERY good, free library for doing everything you'll need.
