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.
