Digital certificate use method and apparatus

Abstract

The invention discloses a digital certificate use method and apparatus. The method includes the steps of: obtaining a verification code and generating a public and private key pair in a trading process; when a client side performs digital certificate signature on information needing to be signed in the trading process by using a private key, obtaining a client private key digital signature of the trading, and generating a digital certificate request including a public key; sending the digital certificate request including the public key, the verification code, and the client private key digital signature of the trading to a network side, wherein the digital certificate request includes trading information, and / or the public and private key pair is generated according to the trading information. After a client user passes the verification according to the verification code and the digital certificate request, the public key is used to perform legality verification on the digital signature according to the trading information at the network side. The trading information and the client private key digital signature of the trading are saved at the network side. By using the digital certificate use method and apparatus, the digital certificate is not dependent on the client side in the use process. Because the trading information is included, the digital certificate can be used as an effective electronicevidence.
