Abstract
Provided are a method and apparatus for managing a digital certificate. A specific implementation of the method includes: receiving a digital certificate generation request sent by a user; according to a digital certificate application scenario, determining a preset threshold value corresponding to the digital certificate application scenario; broadcasting first user information to a blockchain, to enable a blockchain node, which knows an aggregated public key corresponding to the threshold value, to sign the first user information by using a private key component of the blockchain node, so as to generate first signature information, where the aggregated public key corresponding to the threshold value is generated by means of aggregating public key components of the blockchain node on the basis of a signature generation algorithm; and aggregating the first signature information to generate a digital certificate for the user.
