Yeah, there's a couple ways you can do it. But to make it secure you need to either encrypt the passwords and have the listbox decrypt and show. If you were to make any kind of output file for the passwords I would suggest it being encrypted if you are looking for a more secure vault.

I made it out put to a txt file and open read it when it opens up.

There you go! Now, if you want to use it for sure to save passwords you should look up encryption options, the best would be AES-256 bit.

No, that's the last thing you want to do. .ini files are meant to be loaded for actual configurations, not passwords and other stored values.

A simple TXT would be enough, all he would need to do is iterate through each line; add it back to his listBox and all control and functionality would be back for editing the list. Then, when you save; that list is overwritten.

For encryption, he could use the hash of a password that someone provides to be the key when using AES. When the .txt file is being loaded, you're requested to enter the password. You could at the top of the file have an "answer" key that can be read which reads back true if everything is decrypted correctly, else it would remain jumbled letters therefore a simple "incorrect password" would appear.

Just off the top of my head as an idea.

cool program but I'm going to assume you made this with VC++.net which is alright, but can still easily be decompiled
if you want your program far away from being reversed engineered I would go with native C. also rand() doesn't work quiet as well. There are other implementations with hashing algorithms which produce nice random numbers for index.

It just makes it that much more random and that much less easier to reverse.

Just my 2 cents.

Great program otherwise! Looks cool and simple UI. gets the job done

looks awesome.

Thanks buddy!
