Abstract

The invention discloses a data encryption and decryption method and device, computing equipment and a storage medium, and the method comprises the steps: receiving a data encryption storage request and / or a data encryption transmission request, submitted by a first user, for to-be-processed original data; in response to the request, randomly generating a data key, and encrypting the original databy using the data key to obtain first encrypted data; querying a target public key of a second user, and encrypting the data key by using the target public key to obtain a key ciphertext correspondingto the second user; and combining the key ciphertext with the first encrypted data to generate second encrypted data, and storing the second encrypted data and / or transmitting the second encrypted data to a second user. According to the scheme, data storage and / or data transmission can be conveniently completed in an encryption mode, the second user can also conveniently decrypt the encrypted data, and the plaintext of the data key is not stored and / or transmitted, so that the data security is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data encryption and decryption method, device, computing device and storage medium. Background technique [0002] In the prior art, when users need to store or transmit data, in order to prevent the data from being maliciously obtained by others, a password is usually used to encrypt the data to be stored or transmitted, such as setting a password for the data to be stored or transmitted, and then Provide the set password to the data receiver through verbal notification or other communication methods such as chat tools, emails, etc., so that the data receiver can decrypt the received data according to the password, so as to view the data itself. However, no matter whether the password is provided to the data receiver through verbal notification or other means of communication, the password is easy to be obtained by others, which poses a data security risk.
