What does the public key mean?

Public key refers to the key used for encryption and decryption in cryptography, which is usually used to protect the security of network communication. Public key encryption algorithm is an asymmetric encryption algorithm, which can encrypt information safely, and only the owner of the private key can decrypt the information. Therefore, public key plays a key role in ensuring data security.

Public key plays a vital role in modern network communication. By using public key encryption algorithm, users can communicate and trade safely on the Internet without worrying about information being eavesdropped or tampered with. Therefore, public key is an indispensable tool in data transmission security.

Because the security and encryption strength of public keys have been widely recognized, they have been widely used in many fields. For example, e-commerce, medical care and other fields need to use public key encryption algorithm to ensure data security. At the same time, other fields are also trying to use public key encryption algorithm for data protection and encrypted transmission.
