The Dual-Key Revolution: Understanding Asymmetric Cryptography Primarily used for "key exchange," allowing two parties
In the early days of secret-keeping, if you wanted to send a locked box to a friend, you both needed a copy of the exact same key. This "symmetric" approach worked well until the internet arrived. Suddenly, billions of people needed to exchange secrets with strangers they had never met. How do you share a key without someone stealing it in transit?
Think of this as an open padlock. You can hand it out to anyone in the world. Anyone with this "padlock" can use it to lock a message, but they cannot use it to open one.
Unlike symmetric encryption, which uses one key for everything, asymmetric systems use a :
