Free Code Signer v1.7.1

Free Code Signer v1.7.1 is a stability, diagnostics and certificate-inspection update that builds on the major v1.7.0 multi-provider release.

The focus of this version is simple: make everyday signing safer, easier to inspect and more reliable when working with large batches, YubiKey/PIV, smart cards and HSM-backed certificates.

✨ New

Certificate and file inspection

  • Right-click a file and choose Open file location.
  • Right-click a signed file and choose Show certificate.
  • New certificate-details button next to the selected Windows certificate.
  • New detailed certificate view with:
    • Subject and Issuer
    • validity period
    • serial number
    • SHA-1 thumbprint
    • SHA-256 fingerprint
    • public-key algorithm and key size
    • certificate signature algorithm
    • private-key availability
    • Enhanced Key Usage (EKU)
    • certificate-chain status
  • Access to the standard Windows certificate dialog.
  • Signed JAR certificate display when JDK/keytool is available.

Crash diagnostics

Unexpected application errors are now written to:

%LOCALAPPDATA%\FreeCodeSigner\CrashLogs

This makes unexpected UI or signing-workflow failures much easier to diagnose.

🛠 Fixed / improved

Better YubiKey / smart-card / HSM result handling

A non-zero SignTool exit code no longer means that every file in the batch is automatically marked as failed.

Free Code Signer now checks the actual resulting signature of affected files.

If the expected signature is valid, the file is recovered as successfully signed even if the hardware/provider stack returned an ambiguous SignTool/SignerSign error after the signature had already been written.

Large-batch stability

  • Live CLI output is buffered before it reaches the WinForms interface.
  • The visible console is bounded to prevent unlimited UI growth.
  • Verification fallback no longer launches a separate SignTool process for every file.
  • Unexpected exceptions are logged and the application attempts to stay open where possible.

Localization

All new v1.7.1 strings and Help updates are available in all 25 interface languages.

✅ Real-world batch test

The final v1.7.1 build was tested with a 518-file signing/verification job using the Windows Certificate Store / SignTool workflow and a hardware-backed signing certificate.

Result:

  • 518 files processed
  • 518 signatures verified
  • 0 errors
  • 0 interrupted files
  • application UI remained stable throughout the job

🔐 Existing v1.7 features remain

v1.7.1 keeps all major v1.7.0 functionality:

  • Microsoft SignTool / Windows Certificate Store
  • Azure Artifact Signing
  • Google Cloud KMS
  • Jsign universal provider
  • HSM / PKCS#11 / YubiKey/PIV workflows
  • Java JAR signing via jarsigner
  • Standard, Extended, Extended + JAR and Custom file profiles
  • timestamping and signature verification
  • built-in offline Help
  • 25 interface languages
