Abstract

The invention discloses a character string encryption and decryption method and device, a storage medium and a processor. The method comprises the following steps: acquiring original character stringdata and actual encryption environment information; performing length extension on the original character string data to obtain first character string data; grouping and recombining each character ofthe first character string data to obtain second character string data; and performing operation on each character in the second character string data by taking the actual encryption environment information as a scrambling code to obtain an encrypted character string. According to the invention, the security problem that the ciphertext password is easy to crack under the condition that the plaintext password is encrypted through the ciphertext password without using an encryption function library or encryption hardware is solved.

Description

technical field [0001] The present invention relates to the technical field of password security, in particular, to a character string encryption and decryption method, device, storage medium and processor. Background technique [0002] At present, the plaintext passwords (short character strings) used in various occasions, such as system login passwords, database login passwords, compressed package encryption passwords, etc., if the plaintext passwords are directly saved in the file when archiving, or directly stored on the network In the middle of the transmission, there is a great security risk of leaking or intercepting the password. [0003] There are many schemes for encrypting plaintext password strings in the prior art, but there are two disadvantages: 1) generally need additional function library or special hardware support; 2) the encryption algorithm is simple, the ciphertext password is fixed, and it is relatively difficult to crack Small. [0004] In view of t...
