Re: encryption question

I'm not in ANY way an expert on this but....

My understanding is that the usual solution is to create one-way hash of the password (using MD5 or similar algorithms) and store that. Then you can run the same hash on the entered password and see if it matches the saved value. Properly done it should be very hard to get the password from the hashed value.
