Embodiment Construction
[0049] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.
[0050] It should be noted that the "multiple or several" mentioned herein refers to two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character " / " generally indicates that the contextual objects are an "or" relationship.

The invention relates to a document processing method and device, a medium and equipment. In the embodiment of the invention, the modification information document including the information corresponding to the modification of the document can be generated according to the displayed document, and the displayed document and the modification information document corresponding to the document can be respectively encrypted to obtain the corresponding encrypted document. Therefore, the encrypted document corresponding to the displayed document and the encrypted document corresponding to the modification information document corresponding to the document can be generated, and the corresponding encrypted document can be further generated according to the two generated encrypted documents. In this way, modification of the corresponding document can be saved through the encrypted modification information document in the encrypted document, the document needing to be encrypted does not need to be actually modified, the document needing to be encrypted does not need to be repeatedly encrypted; and when the data volume of the document needing to be encrypted is large, the modification efficiency of the document needing to be encrypted is effectively improved.
Description
technical field [0001] The present disclosure relates to the technical field of information security, and in particular to a document processing method, device, medium and equipment. Background technique [0002] This section is intended to provide a background or context for implementations of the disclosure that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, the encryption of the document generally adopts the full-text encryption of the Cipher Block Chaining (CBC, Cipher Block Chaining) mode. In this encryption mode, the ciphertext generated later depends on the ciphertext generated earlier. If the ciphertext generated earlier changes, the ciphertext generated later will also change. Therefore, if the encrypted document needs to be modified, the encrypted document needs to be decrypted first, and after the document is modified, the modified document is encrypted again. [0004] If a ...
