Steganography and encryption tools

This cluster comprises 21 tools focused on steganography (hiding data in images, audio, text, or documents) and encryption, including classic ciphers, OpenPGP, and hybrid cryptography. Dated entries before the index start span from 2013-12 to 2026-04, with a sparse, irregular pattern and a maximum of 2 entries in any single month (2025-02); the early history is too thin to read a clear shape from. Traction leaders are OutGuess-for-Windows (1 star), Gpg Frontend (0 stars), and St (0 stars), indicating minimal public activity.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 20 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
