Update:

  • Added: Infotips for files enabled by default
  • Added: Shell icon overlay handler displays green check/red exclamation when digital signature exists and is valid/invalid

Note that shell icon overlays are not enabled by default because it may be an impact on shell performance. To enable, add a registry value that defines path patterns to be subject for digital signature verification.

Key: HKEY_CLASSES_ROOT\CLSID\{D95FC94B-D292-4566-BEB2-4EB74F2FB561}
Value Name: “Path Expressions”
Value: Comma-separated list of regular expression patterns, eg. “\.((exe)|(dll)|(cab))$” enables the feature for all .exe, .dll and .cab files.
