GitHub
NOURFORGE UTILITIES · WINDOWS APPLICATION

CAPABILITIES
Create durable SHA-256 archive verification data with optional chunk-level evidence for richer future analysis.
Create durable checksum evidence for selected files and archives.
Optionally preserve 16 MiB chunk-level SHA-256 evidence so Checker can calculate how much of a changed file still matches when its whole-file hash no longer does.
Export self-contained Enhanced NourForge Portable Verification Data in fixed-schema TXT or CSV form.
Prepare independent archive and output contexts without collapsing work into one session.
Select and organise configured workspaces for repeatable creation work.
Review results, creation summaries and activity logs, with structured export options.
LEARN
A file hash is compact evidence about exact file content. Creator turns that evidence into a repeatable archive record, then can add chunk-level data for more informative investigation if a file changes later.
