Explaining asym crypto even in simple terms is a nightmare. I have to push explanations multiple times, and not everyone is able to grasp the basic concept of encryption and signing. While people are able to understand symmetric crypto, telling them to encrypt data using someone's else public key causes instant brain twisting and confusion. Add the fact you have to exchange keys from both sides and signing works using private keys, the confusion grows into oblivion
Most of what we post is gone from our own memory within a week, so let's put something here that's meant to be read again.
Write one sentence to yourself five years from now and leave it on the record. Look at your life and circumstances as they stand today, and ask what you would want to read in 2031, looking back on this exact stretch.
A private journal lets you quietly revise the story later. A note signed with your key doesn't give you that option. It sits here with a timestamp, in front of witnesses, saying what you believed and what you were aiming at before you knew how any of it turned out.
One sentence is enough. I'll go first…
"You already knew what was true in 2026, so the only question worth asking is whether you lived like it."
Your turn. I'll be back in five years to read every one. Repost, zap and pass it on.
