Explain private key cryptography
WebKey distribution is a tricky problem and was the impetus for developing asymmetric cryptography. With asymmetric crypto, two different keys are used for encryption and decryption. Every user in an asymmetric cryptosystem has both a public key and a private key. The private key is kept secret at all times, but the public key may be freely ... Webpublic 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.

Public and private keys are an integral component of cryptocurrencies built on blockchain networks that are part of a larger field of cryptography known as Public Key Cryptography (PKC) or Asymmetric Encryption. The goal of PKC is to trivially transition from one state to … WebExplanation: Private key:-A private key is a cryptographic key that is kept secret by its owner and is used for decryption. It is used in symmetric-key encryption, where the same key is used for both encryption and decryption.
