A data encryption and decryption method, electronic equipment and computer program product
By constructing an asynchronous task scheduling framework, the I/O processing thread and the encryption task are decoupled, which solves the problem of strong coupling between encryption/decryption calculations and disk I/O operations, and improves data encryption efficiency and storage media performance.

Abstract
The embodiment of the application is suitable for the technical field of data security, and provides a data encryption and decryption method, an electronic device and a computer program product. The method comprises the following steps: determining a target encryption task unit; the target encryption task unit corresponds to an initial write request of to-be-encrypted data; sending the to-be-encrypted data corresponding to the target encryption task unit to an external encryption device; in the case that encrypted data corresponding to the target encryption task unit is received, updating the initial write request based on the encrypted data, so as to trigger a preset data-driven component to store the encrypted data. The embodiment of the application can decouple the write request and the encryption process of the to-be-encrypted data, avoid the problem of processing blockage of the write request caused by the need to wait for the external encryption device to encrypt the to-be-encrypted data, and improve the data encryption efficiency.
