Cryptographic hashing and checksum utilities

This cluster comprises desktop, web, and mobile utilities for computing cryptographic hashes, verifying file integrity, and in some cases recovering passwords or decrypting protected content. Entries appear sporadically from 2013 to 2022, then pick up to a near-monthly cadence in early 2026 before the index start. Traction is led by ActiveAnticheatDecoder with 7 stars, while crypto-lab and carryall each have 1 star.

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.

  1. 01ActiveAnticheatDecoder20★24 days—An application that decrypts files from the Active Anticheat system.
  2. 02ByteRescue2★19 days—hand-codedhobbyDesktop utility for storage analysis, file inspection, hashing, hex viewing, and signature-based data recovery on Windows.
  3. 03steamverify1★12 days—Game utility that verifies installed game files against official hash manifests and reports files that are not part of the official build.
  4. 04sha256-folder-verify0★17 days—hobbyWindows utility that verifies a copied folder matches the original byte-for-byte using SHA-256 checksums.
  5. 05Argon2 GUI0★5 daysliveopen sourceDesktop utility that hashes passwords and verifies encoded hashes with configurable cost settings entirely offline.
  6. 060x56erify0★10 daysliveopen sourceAndroid app that computes SHA-256 or SHA-512 checksums of selected files and verifies them against pasted hashes to confirm integrity.
  7. 07beatstamp0★18 dayslivehand-codedhobbyWindows desktop app that timestamps files by submitting only a local cryptographic hash to a public log, allowing offline verification that a document existed unchanged at a given time.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
