01
Fingerprint a mixed delivery in one pass
Compute SHA-256 for an image, portrait, PDF, and vector asset together instead of verifying each file separately.
ChecksumsFile Tools
Give every delivery file a fingerprint that can be verified later.
Checksums computes SHA-256 across a mixed set of local files and keeps every digest tied to its source. Copy one value, copy the complete set, or write .sha256 sidecars beside the originals for a handoff another person can verify independently.

What it does
Compute and export trustworthy SHA-256 fingerprints for complete file sets.
Hash images, documents, vectors, archives, and other files together.
Keep each full SHA-256 value beside the correct filename.
Copy one fingerprint or the complete result set.
Write standard .sha256 sidecar files for later verification.
Reveal any source directly from the completed review.
Fingerprint the complete handoff
Keep every SHA-256 digest tied to the file it verifies.
Mixed-format inputs become readable fingerprints that can be copied together or saved as standard sidecars.
02
Review every digest and ship verification sidecars
Keep each complete SHA-256 value beside its source, copy the full set, or write standard .sha256 files that another person can verify independently.
Why it belongs
Why Checksums earns a place in the toolbox.
The practical details that make this job faster, clearer, or safer than doing it by hand.
One batch, mixed formats
A client delivery can be fingerprinted as a set instead of opening a separate command for each file.
Full digests stay readable
Every result row connects the filename, complete SHA-256 value, copy action, and source location.
Verification travels with the handoff
Sidecars let another person verify the exact bytes later with standard checksum tools.
