Text file access method and device and computer readable storage medium

Abstract

The embodiment of the invention discloses a text file access method and device and a medium. The text file access method comprises the steps: randomly calling a secret key from a secret key library tocarry out the encryption of a text file when the text file is obtained, and obtaining ciphertext data. For different text files, the security of text file access is improved in a mode of randomly calling the secret key. After the text file is encrypted, the text file can be maliciously tampered or an error code occurs in the transmission process, and in order to ensure the integrity of the text file, a check value can be set for the text file. Specifically, a check value of a text file can be calculated according to a set rule; and a key identifier corresponding to a key, the check value andthe ciphertext data are spliced to obtain an encrypted file, and the encrypted file is stored. The integrity of the text file is verified according to the verification value. According to the text file access method, the text file is encrypted by randomly calling the key, and the check value is set for the text file, so that the security of text file access is effectively improved.

Description

Technical field [0001] The present invention relates to the field of data security technology, and in particular to a method, device and computer-readable storage medium for accessing text files. Background technique [0002] With the continuous growth of the company’s business, there is a need to provide test tools and test scripts to the outside world, but the content of the test scripts needs to be kept secret, so encrypting the test scripts and the test tools decrypt the encrypted test scripts and execute them. method. [0003] The prior art often uses a single encryption key to encrypt text files such as test scripts. There are often many types and numbers of text files. Once the encryption key is cracked, it will have a serious impact on the security of the company's business. [0004] It can be seen that how to improve the security of text file access is a problem that needs to be solved by those skilled in the art. Summary of the invention [0005] The purpose of the embodi...
