Alice: Signs msg with own private key & uses Bryan's public key is used for encryption Bryan: decrypts with own private key & uses Alice's public key to verify the signed msg.

pki use public key encrypt message,digital signature use private key singi,public key confirm.

Digital Signature Digital signature uses asymmetric cryptography to simulate the security properties of a signature in digital rather than written form.The two types of keys in public-key cryptography are the private key (only the signer knows this key and uses it to create a digital signature) and the public key (it is widely known and the relying party uses it to verify the digital signature).
