Understanding how SSH keys work and how to properly use them has long baffled even some of the most venerable programmers.
In the physical world, a given key usually fits just one lock. We have to special order multiple locks "keyed the same" for entry doors and such. To share access to something, we give out multiple copies of these physical keys.
It's thus tempting to imagine the shared "public key" to be analogous to a physical key and the "private key" to be the lock.
Actually, it's the other way around.
Wogan explains in "How to set up public key ssh authentication" (January, 2014).
Blake Smith's 2010 article, "understanding public key private key concepts" provides the absolute best analogy I've come across.
This brief article lays it as simply and memorably as it gets.
"Why didn't you save us?" said the multitudes before him.
"I sent you my son so you'd learn the nobility of self sacrifice. You didn't.
"I sent you Ebola so you'd learn compassion for those you feared. You didn't.
"I sent you AIDS so you'd learn humility that such things could happen to those you loved. You didn't.
"I sent you terrorism so you'd learn that oppression by the few will always be overthrown by the many. You didn't.
"I sent you climate change so you'd learn to wisely recycle your waste lest nature do it for you... most harshly. You didn't.
"I sent you these things and many more, that your souls might be saved."
"So. Can we go in now?" a man asked.
God replied, "What do you think?"
My own theory goes something like this...
All that we perceive is the result of our imagination.
All raw sensory input is interpreted by our imagination.
If there is little or no sensory input, such as while sleeping or in extreme isolation, our imagination proceeds to rummage around through our memories for "input" to re-interpret.
This extrapolating and recombining and juxtapositioning is the process by which we solve problems and think creatively. The process by which we "imagine."
I've learned that my post back in January 2014 (below) was greatly inaccurate though the result is still essentially the same. -- docsalvage, June 2014

On Income Inequality: A French Economist Vs. An American Capitalist

The healthiest possible economy occurs when 100% of the population feels maximum incentive to risk innovation in the pursuit of happiness (i.e. success).
Because the motivaters of the 1% are mostly in opposition to those of the 99%, maximum prosperity can only be achieved at some point of equilibrium between them. We've been WAY out of equilibrium for about 10-20 years.
