Blackboard knock, knocking blackboard! ! !
A topic that is coupled with a secret! ! !
At this time I think of the brain inside a lot of complex algorithms, etc. However, it is the foundation off, only the second question! ! !
So we simply want to go! ! ! Coupled with a secret? ? ? ?
What do you mean it. . . . . .
Aha, you know, ask you, how many letters? ? ? ? 26! ! ! !
So we shifted a letter after 13 times, is the ciphertext, then backward 13 times not to back the plaintext yet! ! ! ! The figures do not operate.
This is the investigation of the investigation of the legendary ROT13 algorithm. . . . . .
In fact, write a ROT13 algorithm is not difficult, but the main task here is not to write their own, we direct throw it online decryption website.
I use https://www.rot13.com/
Of course there are other, you choose. .
We will see the picture below:
Then enter the website submission
Flattered took another hurdle. . . . . . . . Happy ing
