Asymmetric encryption (public key encryption): refers to encryption and decryption using different key encryption algorithm, also known as public and private key encryption. Suppose two users want to encrypt and exchange data, and both sides exchange public keys. When using, one side encrypts with the other side's public key, and the other side decrypts with its own private key. If there are n users in the enterprise, the enterprise needs to generate N pairs of keys and distribute n public keys. Suppose that a encrypts the message with B's public key and signs it with a's private key. After receiving the message, B first verifies the signature with a's public key, and then decrypts the message with its own private key. Because the public key can be made public, users only need to keep their private key, so the distribution of encryption key will become very simple. At the same time, because each user's private key is unique, other users can not only verify the authenticity of the information source through the sender's public key, but also ensure that the sender can not deny that the information has been sent through digital signature
