  2. Public Key In cryptography, a public key is a large numerical value that is used to encrypt data. The key can be generated by a software program, but more often, it is provided by a trusted, designated authority and made available to everyone through a publicly accessible repository or directory. A private key is another large numerical value that is mathematically linked to the public key.  Private Key Private Key Public Ley Public Ley
