I finally understand Elliptic Curve Cryptography!
Your colleague follows by highlighting their struggles with this mathematical stuff, and then expounds upon all the cool things it can do.
At first you are overjoyed. Then it hits you…
Oh shit…I kinda understand what this guy is talking about, and I haven’t even hit the hard liquor this evening. Dammit…now I’ve got to explain what he’s just done in plain English. Like in writing. @#$%!
On second thought, I don’t have a clue.
Then you go to bed, and hope hell freezes over by morning.
