![]() To do this, Bob takes Alice’s public key and encrypts his message to her. Public and private keys: an exampleīob wants to send Alice an encrypted email. If you encode a message using a person’s public key, they can only decode it using their matching private key. Together, they are used to encrypt and decrypt messages. In public key cryptography, every public key matches to only one private key. Public and private keys form the basis for public key cryptography, also known as asymmetric cryptography. How public and private key encryption works For a detailed understanding of PreVeil’s public-private key architecture, please check out our architectural whitepaper. The blog below provides a general overview on public and private key pairs rather than an architectural overview of PreVeil. We thought it would be helpful to discuss what these keys are, what they aren’t, and how they work. ![]() ![]() ![]() At PreVeil we often find ourselves explaining to our customers the concepts of how public and private keys work.
