Encryption and decryption methods and encryption and decryption systems for webpage identification

Abstract

The invention provides encryption and decryption methods and encryption and decryption systems for a webpage identification. The encryption method comprises the steps of acquiring target address information to be shared according to a webpage address sharing request, and obtaining a target webpage identification by parsing the target address information; performing salting treatment on the target webpage identification with a first fixed value, and then coding the identification to obtain a second character string; further performing salting treatment with a second fixed value and using a hash algorithm to generate a hash value, and cutting out n characters from the hash value as a fourth character string; and jointing the second character string with the fourth character string to obtain an encrypted webpage identification. The decryption method comprises the steps of disassembling the encrypted webpage identification according to a preset m value to obtain a fifth character string, and then decoding the fifth character string to obtain a seventh character string; and performing the inverse operation of salting treatment on the seven character string with a first preset value to obtain the webpage identification. According to the method of the invention, the encrypted webpage identification is short, prone to be shared to third-party applications, and also good in security.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to an encryption and decryption method and an encryption and decryption system for a webpage identification. Background technique [0002] With the continuous development of the Internet industry, the content page of the web page usually uses an identification (identification, ID) as the main parameter of the content page to pass to obtain the specific content of the content page. Among the encoding methods of ID, the most commonly used method is to adopt the method of automatic sequence increment. In order to increase the security of the ID and prevent access based on the increment of the ID, the current common solution is to directly perform symmetric encryption on the ID, such as AES and DES encryption. [0003] However, there are at least the following problems in the way of directly performing symmetric encryption on the ID in the current technology: [0004] (1) The length of the...

Problems solved by technology

Such an address will take up a lot of space when it needs to be shared by a third party (for example, there is a length limit for sharing to Weibo).
