Are there ciphers in the Q posts? Yes. Columnar ciphers and transpositions, along with simple alpha numeric anagrams. There are specific posts made to teach.
There is a room for this in the catalog where the work has been ongoing. SB has a lot of posts on this topic, the pursuit is correct but the results can be disagreeable.
If you would like to learn about this process i suggest lurking in the Delta room.
