Abstract

The embodiment of the invention discloses a data encryption method and device and a storage medium, and the method comprises the steps: receiving an encryption request which is used for indicating to-be-encrypted data; obtaining a first random number for encryption from a server according to the encryption request; obtaining a second random number for encryption from the local; generating a firstsecret key according to the first random number and the second random number; and performing encryption processing on the data according to the first key to obtain encrypted data. According to the scheme, the secret key factors including the network secret key factor (the first random number) and the local secret key factor (the second random number) are dispersedly stored, the secret key is generated according to the dispersedly stored secret key factors when needed, the data is encrypted according to the secret key, and the purpose of improving the data security can be achieved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data encryption method, device and storage medium. Background technique [0002] At present, terminals such as tablet computers and mobile phones can expand their own functions by installing various applications, such as installing instant messaging applications, so that the terminals can provide instant messaging functions. Correspondingly, some data of the application needs to be stored locally on the terminal in order to function normally. However, there is no corresponding security measure in the prior art to ensure the security of these data, so that these data are easy to leak, and there is a problem of poor security. Contents of the invention [0003] Embodiments of the present invention provide a data encryption method, device, and storage medium, which can improve data security. [0004] An embodiment of the present invention provides a data e...
