Group recording file decryption method and device, server and storage medium

The invention provides a group recording file decryption method and device, a server and a storage medium. The method comprises the following steps: acquiring certificate information and a user decryption private key from a key management server; based on the certificate information and the user decryption private key, determining decryption parameters of a plurality of group recording files pushed by the group management server; in response to a received decryption request of the target group recorded file, the decryption request carries recording information of the target group recorded file, and the recording information comprises a target group key identifier; based on the target group key identifier, obtaining target group key information corresponding to the target group key identifier from decryption parameters of the plurality of group recording files; and decrypting the plurality of data packets included in the target group recording file according to the target group key information to obtain a plai
