Public key cryptography provides a secure way to exchange information and authenticate users by using pairs of keys. If you want to encrypt a message to Alice, you encrypt it using Alice's public key, and she decrypts it with Public key encryption provides confidentiality because the message is encrypted with an individual's public key and can only be decrypted with the individual's private key, ensuring that only the intended Open PGP encryption enables you to store sensitive information or transmit that information across insecure networks, such as the internet or email, so that it In my case, I want to ensure authenticity so I encrypt the data with the private key and allow anyone to decrypt it with the public key. The public key is used RSA (Rivest-Shamir-Adleman) is an asymmetric encryption algorithm that uses two mathematically linked keys — a public key to encrypt and a private key to decrypt. net framework), how are the public and private keys used?
