In public-key cryptography, also known asasymmetric cryptography, the encryption mechanism relies upon two related keys,a public key and a private key. The public key is used to encrypt the message, while only the owner of the private key can decrypt the message. ...
I can use its public key to decrypt the data, as only his public key can do it. If I have no its public key or I have a fake key then I can't get its decrypted data.So the private key is called "digital signature". By public key and private key, we can prove the identity ...
