As the random salt - i.e., a 10 character long string, from the sha1() sum of a random number.

Then do:

php Syntax (Toggle Plain Text) 
  1. $encPass = sha1( sha1($origPass) . $hash );

or something like that. Then store both variables in a database for when it comes to checking the login.

That's the basic idea, anywhoo.

im pretty sure that is ok o use just sha1 being its a forty char long encryption.
I wonder what the world will be like in a few years time when that 4TB cd comes out where TB's of diskspace can be stored on just a few disks. So it would be possible to make to have a cd collection containing compressed dehashing data to the 7 digits. That's only the near future as in a few years. In maybe 15 years we may be able to store 15 digits on server farms during the time when a cd holds 23PB (petabytes) and each harddrive in the server farm contains 256EB (ExaBytes = 1024^6 bytes). What is your advice on preventing serverfarms dehashing where a single computer can hold 256EB and there could be hundreds of computers on a hackers personal server farm. Well Google will need somewhere to store all of those youtube videos in the future. That is when the world goes into crises which I am already thinking about preventing today. So my advice, don't wait till the year 10,000 for the millennium bug. Fix it right away.
Try not to bump 10 year old threads as it can be really annoying.

It isn't illegal to dehash a hash unless you intend to use the crack for stealing passwords etc. So if for example you wanted to encode data and decode it using hashes that is not illegal. It is only illegal once you start stealing peoples passwords and one day a hash function on it's own will be very useless unless additional heavy security measures are taken.

I was meaning that in the future todays hash functions will eventually be used as encryption functions as they would in the future easily be decrypted. But the technology is till to come in many many years so most people don't worry about that part of future security unlike myself who secures every piece by future standards.

That's nothing to do with encrypting/decrypting, just means that something went wrong on your host's end with (most probably) Apache.

i dont tink they wil fix it i made a forum post they said its a error that is rare and that the unhasing seemed like nothing to do with it whne i red the posts they made. then i heard that its caused by stuff that i know i didnt do. so it must be the dehasing they are liars. i think they want to incriminate anyone for dehashing when they dont~ i dont dehash i am not a cirminal
