Clear the S/MIME Recipient Certificate List

See more MIME Examples

Demonstrates ClearEncryptCerts, which empties the recipient-certificate list previously populated by AddEncryptCert. This is useful to start over with a different set of recipients before calling EncryptN.

Background. The recipient list is internal state that accumulates across AddEncryptCert calls. ClearEncryptCerts resets it so a subsequent EncryptN encrypts only for the certificates added afterward.
