Public Key Encryption Overview

What is Public Key encryption?

How does Public Key encryption work?

Answer:

Public Key encryption is a type of encryption that uses pairs of keys to encrypt and decrypt data. It involves a public key, which is shared with everyone, and a private key, which is kept secret. When data is encrypted with a public key, it can only be decrypted by the corresponding private key.

Public Key encryption: Public Key encryption, also known as asymmetric cryptography, is a form of encryption where a pair of keys is used to encrypt and decrypt data. This pair of keys consists of a public key, which is widely distributed and used to encrypt data, and a private key, which is kept secret and used to decrypt the data.

Working of Public Key encryption: When someone wants to send encrypted data to another party, they use the recipient's public key to encrypt the data. The encrypted data can only be decrypted by the recipient's private key. This ensures secure communication and data protection.

Secure data transfer: With Public Key encryption, sensitive information like passwords, financial data, and communication messages can be securely transmitted over networks. The use of public and private keys ensures that only the intended recipient can decrypt the data.
