Redact secrets from screenshots. Native on Windows.

Capture a region with Ctrl+Shift+2 — or paste a screenshot — and Blackbar finds IPs, hostnames, API keys, JWTs, hashes and connection strings and destroys the pixels: not a blur you can undo, an opaque burn into a fresh bitmap with every scrap of metadata stripped. Runs entirely on your machine. No account, no telemetry, no network calls.

§ 01 BLACKBAR ON WINDOWS

Seven secrets, boxed in one pass.

Consistent session pseudonyms — the same value becomes the same label ([IP-1], [HOST-1], [AWSKEY-1]) across every screenshot in a report.

§ 02 BEFORE / AFTER

Raw terminal with credentials — Beforelooted creds.txt

Same terminal with every secret burned to a labeled black bar — Afterpixels destroyed, metadata stripped

FIG. 04GUARANTEE

§ 03 OFFLINE, VERIFIABLE

Built-in capture: Ctrl+Shift+2 hands off to the Windows snip overlay — the same one Win+Shift+S uses — and the region lands straight in the editor. The shot never touches disk.
The installer bundles the OCR models and fonts — Blackbar opens no sockets and needs no runtime downloads.
Exports overwrite pixels in a fresh opaque bitmap and strip all EXIF/XMP/metadata — the original is unrecoverable.
Blur and pixelate are flagged reversible and never applied to a secret without an explicit confirmation.
Same 27 detectors, redaction engine and session pseudonyms as the macOS and Linux builds — verified against one shared test corpus, run on x64 and ARM64.
One offline Ed25519 license activates Windows, macOS and Linux — the same emailed code.

§ 04 INSTALLER OR MSI

Installer or MSI.

Run the installer and you are done. The MSI is there for fleet deployment via Intune, SCCM or Group Policy. Windows on ARM gets a native ARM64 build — no emulation.

# silent install (x64)
msiexec /i Blackbar_1.0.0_x64_en-US.msi /qn /norestart

# silent install (ARM64)
msiexec /i Blackbar_1.0.0_arm64_en-US.msi /qn /norestart

§ 4B CHECK WHAT YOU DOWNLOADED

The Windows installer is not yet Authenticode-signed, so SmartScreen may warn on first run — choose More info → Run anyway. The signed SHA-256 manifest below is how you verify it is genuinely ours.

Every release ships a SHA-256 manifest and a GPG signature. Confirm your download is intact and really came from us.

# fetch the manifest, signature and key
curl.exe -O https://dl.getblackbar.com/SHASUMS256.txt
curl.exe -O https://dl.getblackbar.com/SHASUMS256.txt.asc
curl.exe -O https://dl.getblackbar.com/blackbar-signing-key.asc

# check the hash, then the signature
