It consists of two keys: a public key and a private  key. The public key and private key have a mathematical relationship, meaning that data encrypted with one key can only be decrypted with the other key. In encrypted communication, the sender uses the recipient's public key to encrypt the data, and the recipient uses their own private key to decrypt it. This method ensures the confidentiality and integrity of the data, as it employs asymmetric encryption algorithms and avoids the risk of transmitting keys. In China, keypair technology is widely applied in areas such as network security, digital currencies, and privacy protection."}]}],"pr":"124cebc763f70b18ce56afa8f233662af51a3944b1bfe353d6f65b613fb57141"}
