I was just thinking too much on how to make my databse secure maybe thats why I got into this. Sorry though hehe. So, in your opinion, what would be your advise if I wanted to salt this password for a 1000 times and then hash it as this was a comment from another person who replied my email. Is it okay or the suggestion you made is secured enough. Kindly awaiting your reply on this. And thank you very much for replying me Mr Gautham. Really appreciate it.

I was wondering if wad is running in my mind can be executed. Well, I would make a application where a part of it wil be promting the guest to register and I wanted to store the password in the database. I did some research and came across Salting and Hashing. I was wondering if is it possible to get the password which the user enters, salt it, hash it and encrypt it before I store in the database. If so, what is the best secured strong encryption can I use in VB.net. Because through out the research I have done, i have sen RInjdael as the most fav encryption algo which alot of programmers using. JUst a though on this. Kindly advise me. Thank you for your generous help and for reading query.
