How data is encrypted using public key?

How is data encrypted using public key encryption?

Public key encryption uses two different keys. One key is used to encrypt the information and the other is used to decrypt the information. Sometimes this is referred to as asymmetric encryption because two keys are required to make the system and/or process work securely.

Can public key be used to encrypt?

A look at the encryption algorithm and its security benefits Unlike symmetric key algorithms that rely on one key to both encrypt and decrypt, each key performs a unique function. The public key is used to encrypt and the private key is used to decrypt.

Why public key is used for encryption?

Public key cryptography remains the most secure protocol (over private key cryptography) because users never need to transmit or reveal their private keys to anyone, which lessens the chances of cyber criminals discovering an individual's secret key during the transmission.

How does public key encryption ensure confidentiality?

Public-key encryption, also known as asymmetric encryption, solves both shared key risk and the distribution key problem. Instead of a single key, the public-key encryption system uses a pair of keys which are mathematically linked to each other--one of which is kept secret and the other which is transmitted.
