Problems solved by technology

[0002] Encrypting data is an effective technical means to protect information security. There are many data encryption methods in traditional technology, such as MD5 (Message Digest Algorithm 5, fifth edition of message digest algorithm), PHP (Hypertext Preprocessor, hypertext preprocessor) Mcrypt (an encryption extension library), etc., but MD5 is a one-way encryption, which cannot be decrypted and restored, and Mcrypt in PHP cannot be directly displayed or display garbled characters after encryption, which is inconvenient to view and enter, and the configuration is cumbersome, etc. Traditional Data encryption methods have been difficult to meet the security needs of rapidly developing information technology

Abstract

The present invention provides a data encryption method, the method comprising: according to the mapping relationship between characters and numerical values ​​in a preset character library, mapping characters to be encrypted to a first numerical value in a first preset base system in units of bytes; Using the first numerical value as the numerical value of the second preset base and converting the first numerical value into a second numerical value of the third preset base to obtain encrypted data; wherein, the second preset base The base is between the base of the first preset base and the base of the third preset base. The data encryption method provided by the present invention cleverly uses the inclusion relationship of mathematical symbols between different bases to perform base conversion, thereby efficiently implementing encryption of characters to be encrypted and saving storage space. The invention also provides a data decryption method, a data encryption device and a data decryption device.
