About:
Osslsigncode is a command-line utility that leverages OpenSSL to apply digital signatures to Windows executables, installers, and Java archives. It enables developers to sign software releases for distribution without requiring proprietary tools or operating systems. The tool supports timestamping to ensure signatures remain valid after certificate expiration.
Key Features:
  • Cross-platform Authenticode signing using OpenSSL
  • Support for PE, MSI, CAB, and Java JAR files
  • RFC 3161 timestamping support
  • Signature stamping and modification capabilities
  • No dependency on Microsoft tools or libraries
Use Cases:
  • Signing Windows binaries in Linux/macOS CI/CD pipelines
  • Open-source project distribution without Windows licensing costs
  • Automated build processes for cross-platform software
Alternatives:
  • Microsoft SignTool – Official Microsoft tool, requires Windows and SDK installation
  • jarsigner – Java-specific, only signs JAR files, not PE/MSI/CAB
