What Is a Public Key?
A public key is a type of cryptographic code that allows users to securely exchange data over the internet. It is used in conjunction with a private key, which only the user knows and keeps secret. The two keys are mathematically related, but it is impossible to derive one from the other. Public keys are typically generated by an algorithm and stored on servers or databases for easy access by anyone who needs them.
Public keys can be used for various purposes such as encrypting messages, verifying digital signatures, authenticating users, and establishing secure connections between computers. They also provide a way to prove ownership of digital assets without having to reveal any personal information about the owner. This makes them ideal for use in online transactions where privacy and security are paramount concerns.
