Abstract

The invention discloses a file encryption method and a file encryption device, which are used for solving the technical problem that the existing encryption mode is easy to cause data leakage. The method comprises the following steps: generating an asymmetric key according to a preset key layer number through a preset key algorithm, and storing the asymmetric key in a key server, the asymmetric key comprising a public key secret key and a private key secret key; obtaining a public key secret key in the key server, and encrypting a to-be-encrypted file through the public key and a pre-generated random code to obtain an encrypted file; and obtaining a private key in the key server, and decrypting the encrypted file based on the private key to obtain a to-be-encrypted file. By means of the method, safe encryption of the file is achieved, the reliability of the encrypted file is guaranteed, and the leakage risk is avoided.

Description

technical field [0001] The present application relates to the technical field of file encryption, in particular to a file encryption method and device. Background technique [0002] In today's society, science and technology are developing more and more rapidly. In the era of big data, the ways of data generation and acquisition are becoming more and more diverse. Various electronic devices and software can easily collect personal information, hackers, and loopholes. Troubled us all the time, in order to protect data from being destroyed, changed, or leaked due to accidental or malicious reasons, data security has become particularly important. Encrypting data is an indispensable part of it. Data encryption can make the data difficult to be cracked and read, thus ensuring the availability, integrity and confidentiality of the data. [0003] At present, there are various ways of data encryption. Many data encryption is based on the rules of the private key to encrypt data. B...
