I'll give you my home address. You can find the postal code (public key) of my home. You can write my home zip code (public key)+address to me and mail it to my home mailbox. I will open the mailbox (private key) with the key that only I have. The key to the express cabinet is kept in my wallet (wallet)

1. The mailbox was stolen (the database was stolen).

2. The key is stolen (the private key is stolen)

3. Knowing my home address (the public key was stolen), the lock of the postal cabinet was violently opened (the private key was violently cracked).
