Public Key Cryptography

A public and private key asymmetryIn Internet communications, there is a need to manage identity and security for every user. It is called Public Key Infrastructure, or PKI. And what enables PKI to function is its core technology known as Public Key Cryptography or PKC. It is an asymmetric cryptography framework that utilizes private and public key pairs as a solution to modern computer security challenges in the ever-expanding cryptocurrency ecosystem. Also known as asymmetric cryptography, the two related keys are used in combination to encrypt or decrypt messages. PKC is a mechanism that runs on cryptographic algorithms in protecting sensitive personal data and identities from cyberattacks, unauthorized use, malicious access, and other online crimes.The Workings of a PKCA public key consists of a set of numbers at random that represents the encryption to a message which can only be deciphered by the recipient by the use of the private key pair, equally made up of a random set of numbers. The private key must be secured at all times and be known only to the intended recipient. The key pair must be mathematically related so that it can decrypt whatever is encrypted by its counterpart. Therefore, private keys must be generated by using the same algorithms in creating public keys to create strong key pairs that are mathematically bonded.In a PKC mode, every asymmetric pairing are unique. The sender uses the public key to encrypt information, while the private key is used to decrypt the information by the recipient. As the two keys are different, it makes it possible for the public key to navigate the Internet without compromising the encrypted message as it can only be opened by the one who possesses the corresponding private key. Asymmetric encryption algorithms generate mathematically linked key pairs, the reason why their…
