CLUSTER ENCRYPTION-TEXT-ENCRYPTS · 11 ENTRIES · EARLIEST ENTRY 2024-10-13

Text and file encryption tools

This cluster of 13 products focuses on encrypting and decrypting text messages or files, mostly as Android apps, using algorithms like OpenPGP, AES-256, and age. The dated history spans from 2015 to 2026, with sparse entries before 2026 and a concentration in May–July 2026; the 2026-08 coverage is not counted. Traction leaders are CryptoSafe, PGPony, and Neuron Encrypt, each with 0 stars.

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.
