问题
I'm making a program that has a login. Is there any way to encrypt the normal password so that it can't be read in the data base? I've done a trick but I'm not content with it. What I did was to get the first, mid, and last char only and convert each char into ascii. Is there a way to convert all the text into ascii or something like md5/hash in php?
I'm really sorry about this thing, I haven't mentioned that my project is a VB6 project.
回答1:
Don't use MD5 to store hashed passwords! See stuff like http://www.freerainbowtables.com/ for reasons why. MD5 is thoroughly broken... Check what you have available in VB6 (I'm hardly a VB6 guy ;-)) in the realm of cryptography. Something based on (salted) password-based encryption stuff is what you want, Google for "vb6 pbkdf2", I see a lot of hits there :)

I have been using a class by Phil Fresle for generating MD5 signatures for strings. You can copy and paste the source to create the class. To use it in your application I suggest storing the hash rather than the password. The class source code can be found here.
