Editing Polybius square (section)

=== Method 1 ===
Let's encrypt the word "SOMETEXT" with a [[Caesar cipher]] using a shift equal to the side of our square (5). To do it, locate the letter of the text and insert the one immediately below it in the same column for the ciphertext. If the letter is in the bottom row, take the one from the top of the same column.

Thus, after encryption, we get "xtrkykcy".
