Check if a MIME Tree Contains Encrypted Parts

Demonstrates the Chilkat Mime.ContainsEncryptedParts method, which returns whether the currently visible MIME tree contains a CMS/PKCS #7 encrypted 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: The tree-wide counterpart to IsEncrypted: it finds an encrypted entity nested anywhere in the message, not just at the top. This lets you detect partially-encrypted messages and decide which parts require decryption before processing.
