Hi,

I am curious to get some feedback from you about a little thought 
experiment/hobby project I’ve been working on with some of my coworkers and 
have a very early prototype of the concept.

The question we are trying to answer here is how could we all have ultra strong 
passwords i.e. “!3AbDEE9eE45DCea” that are you unique for each and every 
website, email, social media, etc. service that we use but without having to 
trust any third parties to store them for us protected by single password 
(perhaps with 2 factor authentication, hardware key, etc., admittedly), or to 
use some kind of local password manager that needs to be installed on every 
device you want to use it on with a local encrypted password file.  Lastly, it 
should be extremely resistant to rainbow tables if and when one of your 
passwords is leaked.

The idea is to have a very compact piece of open source code that can run in 
your browser that would help you to generate nearly unbreakable passwords on 
the fly every time you need them instead of storing them somehow, or writing 
them down where other parties may be able to access them.  

Also, clearly, nothing is unbeatable. Garbage in garbage out. If someone knows 
you and your habits they could possibly still break your password- especially 
if they know you use this tool and you put very weak things into it (i.e. 
google 1234 ! 1 - this will make sense when you look at the demo and the FAQ).  
However, the concept is more about: 

1) Not being the “low hanging fruit” when some major site gets hacked and 
usernames and passwords get leaked on the net (i.e. don’t be the guy that is 
“u:billsmith32 p:Password123!” on every site he uses).

2) Not having trust third parties (i.e.what if I don’t want Apple to store all 
my passwords in their cloud?). 

3) Not requiring cumbersome software that requires installation on your 
computer and an encrypted local password file to function (i.e. what if I am a 
friend’s house and I need to login somewhere?).

Known vulnerabilities: Keyloggers, compromised hardware, anyone that can 
observe you.  (We were thinking of adding a virtual keyboard that bounces 
around the screen randomly to help foil key loggers).

Disclaimer: I am not a programmer, I’m sure the code is buggy (and the bugs 
were probably introduced by me and not my coworkers). I am not a mathematician, 
and I’m sure there are far better hash functions to use. I’m also sure that 
there are better ways to handle the forcing of 1 special char, 1 upper, 1 lower 
and 1 number minimum in each password to satisfy the peskiest “your password is 
too weak” systems.  

The most important feedback I’m looking for is, do you think the concept is 
sound and if so why or why not? If you do think it’s sound then I would like to 
know how to improve it? If you think there is potential do you think it is 
worth developing further? Assuming it is sound how can we increase user 
friendliness and/or security?

Did somebody else already think of this and do something similar (high 
probability I guess) - please tell me so I can give credit where credit is due. 
 I thought up this idea on a long car trip a year ago and finally got the 
courage to con my coworkers into helping me build it to the bare minimum stage 
that I could ask some real experts for an opinion. I asked a few friends 
already who are pretty well advanced in computer sciences and nobody called me 
a stark raving idiot so I thought it would be OK to ask a crypto mailing list, 
hope you don’t mind.

If you find any egregious idiocy in the code it is probably my fault because 
I’ve been fooling with it a little bit while being too impatient to get the 
experts to fix it.  I think it still works as a demo though. I am the only 
non-coder of the three that have worked on this so far. The .php version is 
only to have a cool looking animation to go with the demo, this is intended to 
be run locally. If you want to see the very original version it’s there too as 
secretpassv1.html 

Thanks for your time, I look forward to hearing your feedback, good, bad, awful 
or otherwise.
