File identity check
For the official public build 1.4.9, three things must agree: this website as the source, the filename, and SHA-256. A matching hash confirms that you have the published file. It does not, by itself, prove that a program is safe.
Windows verification
Perform these checks before double-clicking the executable. You do not need to upload the file to another service.
Check the source
The application file is served directly by this website. Mirrors, Discord attachments, shortened URLs, link-lockers, and files bundled with “FPS packs” are not the official distribution path.
Check the file
In File Explorer, right-click the downloaded file and choose Properties. Confirm the filename, then use SHA-256 for the actual identity check.
A browser may rename a second copy to something like Luczystrap (1).exe. A renamed file can still have the same hash, so SHA-256 remains the decisive identity check.
Calculate SHA-256
Open PowerShell. Replace the example path with the location of your file, or type Get-FileHash, add a space, drag the file into the PowerShell window, and then append -Algorithm SHA256.
Get-FileHash "C:\Users\you\Downloads\Luczystrap.exe" -Algorithm SHA256
certutil -hashfile "C:\Users\you\Downloads\Luczystrap.exe" SHA256 and use the 64-character value it returns.Compare the result
The calculated SHA-256 must equal the official value below. Letter case does not matter. Spaces added for display do not matter. Every hexadecimal character does.

Interpret the result
If the value matches, you have the same file identified by the official 1.4.9 release record. If it differs, do not open the file. Use the decision block below.
Local comparison
The comparison runs only in this browser tab. Nothing is uploaded or sent to a server.
This tool extracts a 64-character SHA-256 from pasted PowerShell output. It does not read the file itself.
Decision
Your file has the same SHA-256 as the official GitHub 1.4.9 asset. That protects against accidental corruption or a substituted mirror file.
It does not certify the program as harmless or replace a code signature, source review, or security audit.
Luczystrap.exe.What this check cannot prove
A hash answers “is this the same file?” It does not answer every security question.
Version 1.4.9 is not documented with a valid Windows publisher signature. A matching hash therefore does not add a verified publisher identity to the executable.
Check Authenticode status →Public automated services have produced conflicting results for this same SHA-256. A clean label and a suspicious label both require context; neither changes the file’s identity.
Read the scan evidence →The current application source is not public, so the 1.4.9 executable cannot be independently reproduced from the repository.
