What’s the difference? Public key cryptography (asymmetric encryption) involves a pair of keys, while private key cryptography (symmetric encryption) uses a single shared key. Understanding the ...

How keys are distributed is vital to any encryption system. Find out how to do it with the Diffie–Hellman key exchange and using public-key cryptography.
