A type of transposition cipher is the rail fence cipher, which is described here. Here is one such cipher encrypted using the rail fence with 4 rails.
Can you decrypt it?

Put the decoded message in the picoCTF flag format, picoCTF{decoded_message}.
- Once you've understood how the cipher works, it's best to draw it out yourself on paper
We can use bocentriq to decode the flag. The site says to use 4 rails. The result is: "The flag is: WH3R3_D035_7H3_F3NC3_8361N_4ND_3ND_55228140"
picoCTF{WH3R3_D035_7H3_F3NC3_8361N_4ND_3ND_55228140}
