Abstract

The invention discloses a batch data encryption and decryption method, device and readable storage medium, including extracting first data information and second data information in each data to be encrypted, the first data information and the second data information are different data information; generate key information for encryption according to the extracted first data information; use the generated key information to encrypt the second data information to obtain third data information; Generate encrypted data according to the first data information and the third data information. Thus, a part of the data to be encrypted is used to generate a key, and another part of the data to be encrypted is encrypted, and then used to generate encrypted data. Therefore, there is no need to save the key of each data after the batch data is encrypted, so there is no problem of key loss or theft, which improves security.

Description

technical field [0001] The invention relates to the field of data encryption, in particular to a bulk data encryption and decryption method, device and readable storage medium. Background technique [0002] For the encryption of huge data, the traditional encryption algorithm encrypts all data separately, so the key storage of a large amount of encrypted data is a problem, and it is easy to lose or steal, resulting in low security. Contents of the invention [0003] Embodiments of the present invention provide a batch data encryption and decryption method, device, and readable storage medium, which do not need to save the key of each data after batch data encryption, so that there is no problem of key loss or theft, improving security. [0004] One aspect of the present invention provides a batch data encryption method, the method includes: extracting first data information and second data information in each data to be encrypted, the first data information and the second...
