01
Calculate & recognise
Calculate enabled CRCs, sums, XORs and hashes for a selection. See matching stored values beside the data, with byte order and checksum length taken into account.
POLLUXTOOL / BINARY ANALYSIS
A hex editor built
around checksums.
Loading latest release…
A highly customised hex editor focused on checksums and reverse engineering. Inspect binary data, understand how it is stored and make precise changes in one workspace.

01 / CHECKSUM WORKFLOWS
More than a calculated number.
Work from a selected range to a repeatable checksum map. Inspect matches, define what each checksum covers and keep the relationship with your bookmarks.
02
Define checksum zones
Set the covered range and checksum address, validate the stored value and choose automatic updates. Save the zone definitions with your bookmarks.
03 PRO
Find checksums
Search a file for possible zones and algorithms. Review ranked and discarded matches, inspect the evidence, then accept the zones you choose.
04 PRO
Find CRC parameters
Supply multiple samples to identify a known checksum first. For unmatched samples, search for CRC-8, CRC-16 or CRC-32 parameters and apply a matching custom CRC.
Checksum calculation requires sign-in. Available algorithms and tools follow your account access. Search matches are candidates to review; they are not proof of the original file format.
02 / THE REST OF THE WORKSPACE
Keep the details in view.
A practical set of tools for exploring unfamiliar data, comparing versions and turning raw offsets into useful, editable values.
Inspect & edit
Read the same bytes as numbers or text, choose the byte order and work directly in the editor.
- Hex and text editing, numeric views and a configurable data inspector.
- Undo / redo, insert and overwrite, custom paste and repeated paste.
- Value colours, a visual data overview and adjustable rows, fonts and panels.
- Raw binary files, plus Intel HEX, Motorola S-record and Renesas DDI import. PRO IMPORT
Name & interpret
Keep a reusable description of the file beside the bytes, instead of rebuilding your notes for every session.
- Typed bookmarks, collapsible groups, custom colours and address offsets.
- Big / Little Endian, inversion, custom XOR and named values.
- Scaling factors, offsets, units, decimal precision and reusable presets.
- Bookmark import / export with checksum zones and editable values.
Search & compare
Find patterns and follow changes without losing the context of the original file.
- Hex, text and numeric search with filtered results.
- Side-by-side comparison, difference navigation and a temporary address shift.
- Resynchronising comparison to investigate inserted and deleted data.
- String and immediate-value searches, plus scripts for repeatable operations. PRO
03 / YOUR WORKSPACE, YOUR ACCOUNT
Start with the file.
Go deeper when you need to.
The editor runs in your browser. Binary contents and calculations stay on your device; your account manages access and saved preferences.
Basic
The core editing workspace, data inspection, bookmarks, file comparison and 8-bit checksums.
Pro
Advanced analysis tools: checksum discovery, CRC parameter finding, 16-bit and larger checksums, hashes, structured-file imports, string and immediate-value searches, advanced editor mode and scripts.
Features, file-size limits and bookmark allowances depend on your current plan. Open your account to view your access.
