Microsoft SignTool is a command-line utility that comes pre-installed with Windows and is commonly used to sign files digitally, verify signatures, and timestamp files. This utility is instrumental in establishing trust for files and applications by confirming their source and integrity.

Key features

This integration has the following features:

  • Versatile file support: Microsoft SignTool supports many file formats, including executables, DLLs, and Windows Installer packages, giving you considerable flexibility.
  • Signature verification: The utility can verify the digital signatures of files, ensuring their integrity and confirming their origin.
  • Multiple hash algorithm support: SignTool enables you to use various hashing algorithms, providing an additional layer of security and compatibility.
  • Timestamping: The utility has built-in support for timestamping, enabling you to prove the authenticity and integrity of a file over time.
  • Scriptable and automatable: Being a command-line utility, you can easily incorporate SignTool into automated build processes and scripts for seamless operation.

Benefits of integration through PKCS #11

Integrating with provides the following benefits:

  • Enhanced security: Incorporating a for storing and using cryptographic keys substantially mitigates the risk of unauthorized key access and compromise.
  • Optimized performance: Using a , which is designed for high-speed cryptographic operations, enhances the efficiency of the file-signing and verification process.
  • Compliance advantage: Integrating with helps meet compliance regulations, such as FIPS 140-2, that require strong key management and secure cryptographic operations.
  • Operational resilience: Features such as high availability and failover in ensure that your file-signing processes are robust and can continue despite system failures.
  • Centralized key management: provides a centralized point for secure key storage and management, making it easier to administer and safeguard your keys.
