Bitcoin uses cryptographic keys, which are strings of numbers and letters, that can encrypt (hide) and decrypt (reveal) data. The Public Key is used to generate addresses for receiving. You can share these addresses with others so they can send you bitcoin. Your Private Key allows you to spend your bitcoin. It is used to sign transactions when sending bitcoin to others. Important: You must keep your private key SECURE, as anyone who has it can spend your bitcoin!
"For greater privacy, it's best to use bitcoin addresses only once." - Satoshi Nakamoto, 2009-11-25
