| Apr 29, 2019 at 9:09 | comment | added | forest | @customcommander I think a search of this site may show the same techniques that I've described. But note that, in the very possible situation that frequency analysis doesn't work, it might be simply too difficult to decode this cipher without a lot more ciphertext. We usually deal with ciphers where even the most broken ones requires gigabytes of data to even begin to be breakable, so a single cipher with a couple of lines of symbols isn't much for us (or anyone) to go on. My advice is a shot in the dark. | |
| Apr 29, 2019 at 9:08 | comment | added | customcommander | @forest Thank you. This is the kind of answers I was looking for. Maarten Bodewes maybe my question wasn't formulated in the most appropriate way but I feel that closing it down prevents forest from sharing this useful answer to a wider audience (it's useful to me at least). | |
| Apr 29, 2019 at 9:04 | comment | added | forest | I recommend you look into frequency analysis and substitution ciphers. Transliterate the symbols and run a frequency analysis on them. The letter with the highest frequency of use is likely to be the letter e, for example. There are lots of sites that explain how to do this. We can't do that for you. | |
| Apr 29, 2019 at 9:02 | comment | added | Maarten Bodewes Mod | No, we close it mainly because it is just ciphertext. It will still be ciphertext on whatever medium you put it on. Note that SE is trying to build a knowledge base. However, your question is basically only of help to you. We'd have to start all over again for the next ciphertext, without even knowing that there is an answer. | |
| Apr 29, 2019 at 9:00 | comment | added | forest | @customcommander Unfortunately we don't even know if it is a cipher at this point. Even if it is though, simply having the ciphertext isn't usually enough for us to do anything. If you want to know how to properly use frequency analysis to break it, you could ask that (assuming it isn't a duplicate of another question), but we aren't going to be able to simply "decode" it. Cryptography doesn't work like that. | |
| Apr 29, 2019 at 9:00 | comment | added | customcommander | Thank you for your comment. As I'm new to cryptography what may seems obvious to you isn't to me. If I can extract the text would that help? | |
| Apr 29, 2019 at 8:57 | comment | added | Maarten Bodewes Mod | What part is not clear to you w.r.t the reason? This is ciphertext analysis, without additional hints. That it is put on a pretty postcard doesn't make it any different for us. | |
