| Mar 29 at 7:27 | comment | added | codewarrior0 | I concur with LeppyR64. This looks like the key to a transposition cipher. I can imagine that an empty 8x8 grid would be prepared separately, the plaintext written into it in the order given by the bottom number in each cell of the key, and then the ciphertext read out of the prepared grid in the order given by the key's top numbers. Deciphering is the inverse; write into an empty grid using the top numbers, and then read out using the bottom numbers. | |

not about the process of cryptography

| Sep 26, 2017 at 16:05 | comment | added | LeppyR64 | It certainly looks like a transposition cipher or a grille. en.wikipedia.org/wiki/Grille_(cryptography) | |
| Sep 26, 2017 at 13:28 | comment | added | sousben | preliminary comments: lower numbers are consecutive from bottom to top cells and from right to left. 8 consecutive upper numbers appear on each row but not in consecutive order. the order of the rows is 3,2,1,4,5,8,7,6 | |
| Sep 26, 2017 at 13:24 | comment | added | sousben | the second cell from top left should read 56 and not 58, it looks like someone overwrote the lower values with black ink | |
