We know that with symmetric encryption based on Des or Aes, when the plaintext and password are the same, the ciphertext is the same. And we’re the release WJLSymmetricEncryption4. Js (click on the links to jump to the download page) encryption program, when clear and password are the same, the encrypted ciphertext to vary each time, then make further cipher has great randomness, but does not affect the correct decoding.
Taking chat as an example, there are many encrypted chat systems on the market now, and you must have a doubt, such as: does the server have all the chat records? For example, if my chat message is displayed on the computer, will it look at the screen and take a screenshot?
As an algorithm, the application method is very flexible.
I. Features of the algorithm
1, support Chinese password and Chinese encryption and decryption, can be used for link address encryption and decryption;
2, you can encrypt for js, but you need to use the eval() function;
3, the same password and plaintext after each encryption results are different;
4, with compression effect, for html pages or styles, can effectively lossless compression of a certain amount, speed up the efficiency of file transfer, some pages can be compressed more than 80%;
5, pure domestic algorithm, from the bottom of the mathematics is our independent mathematical model – weighted probability model, and then combined with the safety box and round function;
