Fast encryption method for social websites

Abstract

The invention discloses a fast encryption method for social websites. The fast encryption method for the social websites comprises the main steps of disordering for the first time, performing nonlinear encryption for the first time, disordering for the second time and performing nonlinear encryption for the second time. A password character string is disordered on the basis of the conventional message-digest algorithm 5 (MD5) encryption, so the safety of the password is enhanced; and MD5 encryption is performed for two times, so that the original text of the final ciphertext comprises character strings without logical relationship, a hacker needs a brand new original tex / ciphertext control database which does not exist at present and has huge data quantity to decode the, the difficulty of decoding the ciphertext by the hacker is greatly enhanced and the safety of the password is enhanced. The encryption flow only needs one-time communication between a client side and a server side, has low requirement on the network environment and only needs short waiting time, so the using efficiency of users is improved.

Description

technical field [0001] The invention relates to a password encryption method, in particular to a fast encryption method for social networking sites. Background technique [0002] The full name of MD5 is Message-Digest Algorithm 5, which was invented by MIT's Computer Science Laboratory and RSA Data Security Inc in the early 1990s. MD5 transforms a string of any length into a 128-bit large integer, and is an irreversible string conversion method. MD5 encryption module is a module with MD5 encryption function. [0003] Existing social networking sites usually encrypt passwords directly using the MD5 method. Although encryption using MD5 method is irreversible, hackers now have a large amount of MD5 original text / cipher text comparison database, which can quickly decipher the MD5 cipher text of commonly used passwords, and the passwords of users in social networking sites are basically common passwords. The security of the user password is greatly reduced; some social networ...

Problems solved by technology

Although encryption using MD5 method is irreversible, hackers now have a large amount of MD5 original text / cipher text comparison database, which can quickly decipher the MD5 cipher text of commonly used passwords, and the passwords of users in social networking sites are basically common passwords. The security of the user password is greatly reduced; some social networking sites use the interactive encryption method between the client and the server to increase the security of the password, but it often takes multiple interactions to complete the encryption, which requires a better network environment and a longer period of time. Waiting time reduces user efficiency
