Zhou Ziheng clearly felt the changes in Xia Xiqing at this moment. Before, he was lazily staying out of the matter, but when he heard that a player broke through the room, he immediately threw himself into the game.
However, he also knew that Xia Xiqing's behavior was not because of his desire to win, but because he wanted to leave here to watch the excitement.
It is probably his real purpose to stir up the muddy water.
"Don't you think this poem is very strange?" Xia Xiqing found a signature pen from nowhere, and drew a horizontal line on the last few lines of the poem.
[Only re-disassembly,
Return you to me, return me to you.
From top to bottom, connected to each other.
Everything can regain meaning. ]
He took out the sticky note that Zhou Ziheng had spelled together at the beginning, with a string of garbled characters written on the front, "I think this poem hints at the decoding method of this code."
Zhou Ziheng nodded in agreement, and read the poem carefully in his heart.
[We were one.
Fate took you away from my body, from my bones, my flesh, and my heart, and abruptly put these meaningless organs together.
I was buried together with you who were dismantled and reconstructed together.
Buried under this fence with lush roses.
Only re-disassembly,
Return you to me, return me to you.
From top to bottom, connected to each other.
Everything can regain meaning. ]
It used to be one body, separated, pieced together, buried together one after the other
He couldn't help but read out in a deep voice: "Buried under this fence with lush roses"
fence, fence
fence
Suddenly, a flash of light flashed in my mind.
"rail fence cipher."/"rail fence cipher."
The two blurted out at the same time, and then looked at each other in surprise.
Xia Xiqing laughed first, "It seems that I am really an idol. I have a perfect understanding."
Zhou Ziheng sneered in his heart, sorry, he didn't want to be followed by such a person at all.
Having said that, Xia Xiqing's reaction speed still surprised him. "How do you know the password for the fence?" Zhou Ziheng asked.
Xia Xiqing replied casually, "My nephew is in IT, and I studied a little cryptography with him for a while"
Your nephew? Zhou Ziheng frowned and looked at Xia Xiqing.
Where are you from, old goblin?
He didn't say anything, and didn't really believe what Xia Xiqing said. He leaned over and grabbed the pen he found just now to decode the code. Xia Xiqing turned the little poem to the other side and saw [2 you] written on it. , said with a smile, "Actually, the clues of the program group are really obvious. The 2 here is not to, it means that the original state of the password is divided into 2 columns, right?"
"En." Zhou Ziheng counted the long string of garbled digits with his fingers, found the middle one, drew a vertical line, and disassembled them. Although he knew that Xia Xiqing understood the decoding process, in order to ensure the program The audience can also understand this process. Zhou Ziheng explained, "The first half of this poem is the process of encryption, and the beginning of 'only re-disassembly' is a reminder of the decoding process. According to the 2 written on the back, the garbled characters Evenly divided into two groups, with seven letters in each group."
pgoeude aenhnrd
"'Return you to me, return me to you' should refer to dismantling and restoring the letters in the group." While speaking, Zhou Ziheng re-transcribed the two separated groups, aligning the two lines.
pgoeude
aenhnrd
Zhou Ziheng lowered his head, and while reading the penultimate sentence in the poem, "From top to bottom, they are connected to each other." Starting from the letter p in the first line, he drew a line with a pen, first pointing to the a in the second line, and then With a turn of the pen, the line loops back to g, and so on, until this circuitous, rippling line penetrates every letter and reaches the last letter d.
"Write it down in the order of the lines" Zhou Ziheng half-bent down and carefully copied the final answer.
page one hundred
?page one hundred.
"The hundredth page." Xia Xiqing picked up the unbelievably thick book next to him, and turned to the hundredth page.
The entire page was printed with densely packed words like ants, and he saw four numbers on the forty-second line.
[I live only because of my longing, for this blazing cliff.]?
We were once one. [The original plain code is page one hundred, remove the spaces to become one page one hundred]
Fate took you away from my body, from my bones, my flesh, and my heart, and abruptly put these meaningless organs together. [How to "extract", because the column is 2, so divide it two by two and become page on eh un dr ed, a total of seven groups (bones, flesh, heart, etc) and then extract the first number of each group The first character (pgoeude) is placed in one pile, and the second character (aenhnrd) is placed in one pile, which becomes two piles]
I was buried together with you who were dismantled and reconstructed together. [Put together the two piles of letter sequences obtained just now, "one in front and one in back", and you get the password pgoeudeaenhnrd]
So this is the encryption method of the fence password. In the same way, let's give another example, such as encrypting "i love you", if we encrypt in 3 columns
? First remove the space to become iloveyou, then separate three by three, ilo vey ou
Then the first letter of each part is grouped (ivo), the second letter is grouped (leu), and the third letter is grouped (oy)
Finally put them together end to end: ivoleuoy
Dangdangdang, the encryption is complete! (Take it to confess~)
Have you learned the fence code? In fact, the passwords used to set up mobile phones and some accounts every day are very good~
For the decoding part, follow the steps in the text, first divide the garbled characters into two columns, string them together with wavy lines on one line, and write them in order.
get out of class is over~ Do you feel bored? hhhh, just If you are interested, you can try it with a pen and paper. I love you~ (Remember the website URL: www.hlnovel.com
