Luczystrap / Safety / Verify download / Digital signature

Publisher identity · Windows Authenticode

Check the signature—then interpret its limit.

Authenticode can bind a Windows executable to a code-signing certificate and detect changes to signed content. It answers a different question from SHA-256 and a different question from SmartScreen reputation.

Current 1.4.9 finding: the official hash-matched Luczystrap.exe has an empty PE Certificate Table, so it contains no embedded Authenticode signature. The expected standalone Windows status is NotSigned.

01 / Current evidence

Keep the finding tied to one exact file.

The signature result applies only to the official 1.4.9 bytes inspected here. A mirror, wrapper, future release or locally modified file requires its own hash and Authenticode result.

02 / PowerShell check

Ask Windows—not the filename.

Get-AuthenticodeSignature is available only on Windows. It checks embedded signatures and can use a Windows catalog signature when one exists.

Hash first: run this only after the local SHA-256 matches the intended release. Otherwise you may be interpreting a signature from the wrong file.

PowerShell · read-only inspection
$sig = Get-AuthenticodeSignature -LiteralPath "C:\Users\you\Downloads\Luczystrap.exe"
[pscustomobject]@{
  Status             = $sig.Status
  StatusMessage      = $sig.StatusMessage
  SignerSubject      = $sig.SignerCertificate.Subject

Replace the path

Use the exact local EXE. -LiteralPath avoids wildcard interpretation.

02
Run without opening the file

The command reads signature metadata; it does not launch Luczystrap.

03
Save the complete result

Status alone is insufficient when a signer exists. Preserve certificate and timestamp fields too.

03 / File Properties route

The missing tab is a clue, not the full report.

File Explorer can expose embedded signatures without running the EXE. PowerShell remains the better record because it returns an exact status and can account for a Windows catalog signature.

Do not choose Open. Right-click the file, select Properties, inspect the tabs and close the dialog.

General Compatibility Security Digital Signatures
Tab present Open signature details

Read signer name, digest algorithm and certificate. Then verify with PowerShell.

Tab absent No embedded signature shown

This matches the inspected 1.4.9 PE, but still capture PowerShell status.

Unexpected tab Recheck SHA-256

A signed wrapper or altered copy is not automatically the official file.

04 / Status interpreter

Preserve the enum before choosing an action.

Select the exact Status or paste the formatted PowerShell output. The tool classifies Microsoft’s documented result; it does not contact a certificate service or declare the file safe.

Local only: pasted output stays in this browser tab. Remove personal path segments before sharing it elsewhere.

Current 1.4.9 expectation

No Authenticode signature is present.

Windows cannot supply a code-signing publisher identity from this result. Keep that limitation visible; it is neither a malware conviction nor a safety certificate.

Parsed status NotSigned
Signer subject — blank —

05 / Authenticode chain

A signature is more than a badge.

A useful signed-release record connects the exact file to a signer, certificate chain and signing time. Missing one layer changes what can be concluded.

Authenticode records integrity over defined PE content.

06 / Status matrix

Each Windows status has a different next step.

Do not collapse invalid, untrusted, unsigned and unsupported into one vague “signature failed” label.

Status Microsoft meaning Decision for a downloaded EXE
Valid
Review signer
The signature is syntactically valid. Microsoft explicitly says this status alone does not imply trust. Record subject, issuer, thumbprint and timestamp; match SHA-256; continue the wider safety review.
NotSigned
Current 1.4.9
The file has no signature. No Authenticode publisher identity is available. Treat it as a documented trust gap, not a malware verdict.
HashMismatch
Stop
The current file hash does not match the hash stored with its signature. Do not open. Preserve the file and result; obtain a fresh official copy and verify its SHA-256.
NotTrusted
Stop / inspect
The certificate was signed by a publisher not trusted on this system. Do not call it verified. Inspect the full chain and compare with an official signer record.
UnknownError
Stop
The file has an invalid signature. Do not run. Preserve StatusMessage and the exact file identity for investigation.
NotSupportedFileFormat
Wrong boundary
Windows does not support signing or verifying that selected file type. Confirm the path points to the intended PE executable rather than a shortcut, archive or text output.
Incompatible
Retest system
The signature cannot be verified because it is incompatible with the current system. Retest on a supported, updated Windows environment. Do not translate it into NotSigned or Valid.

07 / Three separate checks

Hash, signature and reputation do not replace each other.

A green result in one system cannot erase a gap or warning owned by another system.

SHA-256

“Are these the recorded bytes?”

Compare the local digest with the version-specific value published on this website. A match establishes file identity for practical download verification.

Current 1.4.9: exact match available.
Authenticode

“Who signed these bytes?”

Windows evaluates the signature and certificate information. Current 1.4.9 has no embedded signature or signer fields.

Current 1.4.9: publisher gap.
SmartScreen

“What is the download reputation?”

Microsoft Defender SmartScreen evaluates the reputation of apps and files downloaded from the web. Preserve its exact message.

Separate reputation decision.

08 / Unexpected result

Different does not automatically mean better.

If the current official 1.4.9 record is unsigned but your copy reports a signer, first prove that you still have the same bytes and the same file—not a wrapper, installer or replacement.

Never accept a new signer by appearance alone. A familiar company name in a dialog is not a substitute for an official signer subject, thumbprint and version record.

10 / Direct answers

Digital-signature FAQ.

Is Luczystrap 1.4.9 digitally signed?

The official 1.4.9 file with SHA-256 d71c31057677bc392f680c6303dcfda9fa8f366240284dac6d5a14f7cc352424 has an empty PE Certificate Table, so it contains no embedded Authenticode signature. In ordinary standalone Windows use, the expected Get-AuthenticodeSignature status is NotSigned with blank signer fields.

How do I check the Luczystrap digital signature?

Run Get-AuthenticodeSignature in Windows PowerShell with the exact LiteralPath to Luczystrap.exe, then record Status, StatusMessage, signer subject, issuer, thumbprint and timestamp fields.

What does NotSigned mean in PowerShell?

Microsoft defines NotSigned as the file having no signature. It means Windows cannot obtain an Authenticode publisher identity from that result; it is not by itself proof that the file is malicious or harmless.

Does an unsigned Luczystrap file mean it is malware?

No. Missing Authenticode removes a publisher-identity and signed-integrity signal, but it is not a malware verdict. Keep the limitation visible and evaluate the official source, SHA-256, behavior and other security evidence separately.

Does a Valid Authenticode status prove a file is safe?

No. Microsoft documents Valid as a syntactically valid signature and explicitly says that status alone does not imply trust. Confirm the signer identity, certificate chain, timestamp, file hash and wider behavior.

Is a verified GitHub tag the same as a Windows digital signature?

No. GitHub verification authenticates a Git object such as a commit or tag. Authenticode binds a Windows binary to a code-signing certificate and lets Windows evaluate the signature and certificate chain.

Why can SmartScreen warn when SHA-256 matches?

SHA-256 confirms file identity, while Microsoft Defender SmartScreen evaluates reputation for downloaded apps and files. A matching hash does not create a publisher signature or guarantee a positive reputation result.

What should I do if Luczystrap signature status is unexpected?

Do not open the file. Recheck the official source and SHA-256, confirm the exact path, preserve the complete PowerShell output and certificate fields, then compare the result with the version-specific record before deciding what changed.
