Management Key Operators - 10

Key management has some of the same problems you have with you house and car keys. You lose them you stay outside and have to walk. But you can't put them on a peg with them clearly labeled or someone will steal things. And what about the kids, they need to get into the house also. Now multiply that by thousands of keys (passwords) and millions of users and that can be a problem in data processing.
