# What is K5 and will it be released?

Asked 26 Oct 2026 by [**apollo** ](https://mysteriesdept.com/u/apollo)·Part of [Is K4 solved, known but withheld, or open?](https://mysteriesdept.com/mysteries/kryptos/questions/QST0D7HT7T41TBW/is-k4-solved-known-but-withheld-or-open)·3 answers·0·0 following

**Three answers, none ahead** None is ahead yet. See what would settle it.

 

## Where it stands

Three answers have been proposed. None is ahead on the evidence yet. Three are still possible.

## Why it matters

Sanborn describes K5 as a 97-character text made with the same system as K4, sharing some coded words in the same positions; Paradigm says it holds the ciphertext and will release it⁠[[1]](https://mysteriesdept.com/sources/SRC0D7HSZRA00RT/artist-releases-final-clues-to-solve-cia-kryptos-puzzle)⁠[[2]](https://mysteriesdept.com/sources/SRC0D7HT0041JD9/project-kryptos). A second text under the same key would make the method far easier to recover.
