Public key cryptography is an encryption technique that uses a paired public and private key to encrypt and decrypt data. The public key is used to encrypt and the private key is used to decrypt. The public key can be shared freely allowing the user to use an easy and convenient method for encrypting the content while private keys can be kept secret.
As public keys are too big to be remembered, they are stored on digital certificates for secure sharing, while private keys are stored in the operating system.
In a public key encryption system, one can encrypt a message with the help of the public key of the receiver while the message can be decrypted only with the receiver’s private key.
