Looking for comments on a program I made

[Pi rules]

I recently made a program in VB that computes a hash value to hopefully provide the ability to create a secure password that may be recalculated at any time. The program asks for the site's domain (like kickenhardware.net) and a secret "code" such as the main password you use. It combines these inputs and calculates a hash, which is converted into and limited to any key on a standard English keyboard.

I have a beta version available for download here (see post below, link not valid) (.NET Framework 2.0 required), and I was wondering if anybody could try it and offer any sort of comments on usability, security, the interface, etc. But, the calculation method might change, so don't use it for passwords yet. If you don't think that you know a whole lot about programming, that's good since I need advice on how easy it is to use.

The program works by calculating an MD5 hash from a combined input, then I "fix" the output if the ASCII value is not on a standard keyboard. Sample password for "kickenhardware.net" and "test" - 6Q<CQ(@.!&,F]D+1. Not too easily cracked.;) Again, any comment, suggestion, or criticism at all is welcome.

Edit - fixed link.

An installer that creates shortcuts on the desktop and Start Menu is available here (http://www.mediafire.com/?6nxjvyz92bj). - edit, link no longer valid, see below

All good, should probily sort out the fact that the Delete key is counted as a key if you use it in the code box.

Good work tho buddy

You mean like the magic password firefox extension? You enter a secret password and based on the site you're on it creates a random alphanumeric password. (9 characters)

It's a good idea but it works best built into a web-browser IMO

New version with several fixes thanks to feedback...

All good, should probily sort out the fact that the Delete key is counted as a key if you use it in the code box. Yeah, I'm working on a way to fix that. The current way I change it to asterisks doesn't work too well if you want to change the code.

It's a good idea but it works best built into a web-browser IMO That's what I was thinking, but I don't yet know how and college is coming up too soon to learn how.

I decided to change my method of changing the input to asterisks. It is a little less secure, but much more user-friendly. I also did a lot since the last download links. You can now choose the hash function (MD5, SHA-1, SHA-256, SHA-512, and RIPEMD-160) and number of characters in the password (up to 32 with SHA-256 or SHA-512)

arr I like the new results box, dosnt give it you just puts it on the clip board.

I changed a lot again... New checkbox to show advanced options and drop downs instead of menus. I'm working on calculating the hash of a file to use instead of the code, but the file obviously can't change or people are in trouble...
