Data acquisition and data transmission method, terminal, server and storage medium

The embodiment of the invention provides a data acquisition method, a data transmission method, a terminal, a server and a storage medium, the data acquisition method comprises the following steps: sending a decryption request for at least one encrypted file to the server, the decryption request comprising the size of encrypted data of each encrypted file and information used for determining data used for decryption; when the decryption quota of the client is larger than or equal to the total amount of the encrypted data corresponding to the decryption request, data returned by the server and used for decryption are received, the decryption quota of the client indicates how much encrypted data can be decrypted at most at present, and the decryption quota of the client indicates how much encrypted data can be decrypted at most at present. The total amount of the encrypted data corresponding to the decryption request is the sum of the sizes of the encrypted data of each encrypted file; and based on the data for
