Check if a MIME Tree Contains Signed Parts
See more MIME Examples
Demonstrates the Chilkat Mime.ContainsSignedParts method, which returns whether the currently visible MIME tree contains a complete detached or opaque CMS/PKCS #7 signed entity. It takes no arguments.
Note: The file path is relative to the application's current working directory. Absolute paths may also be used. Supply the path to your own file.
Background: Where
IsSigned asks whether the top entity is a signature wrapper, this scans the whole tree for a signed part nested anywhere inside — useful when signing is applied to a sub-part rather than the outermost entity. It is the discovery step before deciding whether verification is needed.Chilkat Visual Basic 6.0 Downloads
