If one of the keys is used to encrypt data, only the corresponding key can be decrypted.
If one of the keys can be used for data decryption, the data must be encrypted by the corresponding key.
The main application of asymmetric key cryptography is public key encryption and public key authentication. The process of public key encryption is different from that of public key authentication. I will explain in detail the d

Principles of Public Key and private key:
A public key corresponds to a private key.
The key pair is known to everyone as a public key. If you do not know it, you only know it as a private key.
If one of the keys is used to encrypt data, only the corresponding key can be decrypted.
If one of the keys can be used for data decryption, the data must be encrypted by the corresponding key.

User identity authenticationAre you sure you want to contact me?
Ensure content confidentialityAnd cannot let others know what we are talking about.
Ensure content integrityEnsure that the information I receive is the information sent by the other party, rather than forged by others.
