Download Hash Calculator
Forensic-grade file integrity tool. Multi-algorithm hashing, tamper-evident audit log, snapshot & verify, self-integrity reports — read-only on evidence media, by design.
Open beta — just launched
By downloading, you agree to the End-User License Agreement.
Verify Before You Install
Forensic users hash everything. Hash the installer first.
After downloading, confirm the file's SHA-256 fingerprint matches the value below. If the values do not match, do not run the installer — contact us.
Compute on Windows (PowerShell)
Get-FileHash .\HashCalculator-1.2.1-Setup.exe -Algorithm SHA256
Compute on Windows (cmd)
certutil -hashfile HashCalculator-1.2.1-Setup.exe SHA256
Compute on macOS / Linux
shasum -a 256 HashCalculator-1.2.1-Setup.exe
About the SmartScreen Warning
"Microsoft Defender SmartScreen prevented an unrecognized app from starting."
This is normal for unsigned beta software. To proceed:
- Click More info in the SmartScreen dialog.
- Click Run anyway.
- The installer wizard opens. Accept the End-User License Agreement and follow the prompts.
The General Availability release will be code-signed, after which Windows will no longer display the warning.
What You Get
Everything that makes Hash Calculator a forensic-grade tool, in one self-contained installer.
Multi-Algorithm Hashing
MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA3-256/512, BLAKE2b, BLAKE3, RIPEMD-160, Whirlpool and more — computed in a single streaming pass via Bouncy Castle.
Tamper-Evident Audit Log
Every action is hash-chained. Tamper with any past row, and every subsequent row breaks — chain-of-custody documentation that defends itself.
Snapshot & Verify
Capture a folder's state today. Prove nothing has drifted six months from now — file by file, to the byte.
Self-Integrity Reports
HTML reports carry their own SHA-256 inside. Change one character and the report reports that it has been tampered with.
Read-Only On Evidence
Hash Calculator never modifies the source media you are examining. Not a single byte. The first rule of digital forensics, enforced by design.
CLI Mode
Full command-line interface for scripted and automated forensic workflows. Pipe results into your existing tooling.

Before You Install — Legal Documents
The installer displays the End-User License Agreement on the License page of the wizard, and you must accept it before installation proceeds. You can read both documents in advance:
- End-User License Agreement (EULA) — the binding contract between you and Innovativa SoftTech Solutions Private Limited.
- Third-Party Notices — attributions for bundled open-source components.
Download Frequently Asked Questions
Why does Windows show a SmartScreen warning?
Hash Calculator v1.2.1 is an unsigned beta build. Windows SmartScreen warns about all unsigned software. Click More info → Run anyway to proceed. The General Availability release will be code-signed, after which the warning will not appear.
Do I need to install Java separately?
No. The installer bundles a stripped-down OpenJDK 24 runtime. You do not need Java installed on your machine.
How big is the download?
The Windows installer is approximately 58 MB. It contains the bundled Java runtime, JavaFX UI libraries, Bouncy Castle cryptography, SQLite database driver, and the application itself.
How do I verify the installer is genuine?
Run certutil -hashfile HashCalculator-1.2.1-Setup.exe SHA256 in Windows (or shasum -a 256 ... on macOS/Linux). The resulting SHA-256 must match the value published on this page. If they don’t match, do not run the installer — contact us.
What does the End-User License Agreement cover?
The EULA covers hostname-bound licensing, permitted use, read-only operation guarantee, audit-rights for license compliance, and Maharashtra (India) jurisdiction. Read the full text via the “EULA” link above before installing.
Can I install this on multiple computers?
Each license is bound to a single hostname/hardware fingerprint. Installing on additional machines requires additional licenses. Multi-seat commercial licensing is available for forensic labs, audit teams, and government departments — contact Pallavi on +91 8484859088.
Does Hash Calculator send any data to your servers?
No. All case data, audit logs, snapshots, and hashes stay on your local machine. The application does not transmit anything to Innovativa SoftTech as part of its normal operation. Optional anonymized crash diagnostics require explicit per-event consent.
What if my antivirus blocks the download?
Unsigned forensic tools are sometimes flagged by aggressive antivirus heuristics. Verify the SHA-256 first — if it matches, add an exception in your antivirus and re-download. If your antivirus still blocks it after verification, contact Pallavi.
