The certificate (PEM/base64 encoded).
When RecipientCertEncoded is set, a search is initiated in the current RecipientCertStore for the private key of the certificate. If the key is found, RecipientCertSubject is updated to reflect the full subject of the selected certificate, otherwise RecipientCertSubject is set to empty string.
The RecipientCertIndex parameter specifies the index of the item in the array. The size of the array is controlled by the RecipientCertCount property.
To read or write binary data to the property, a Variant (Byte Array) version is provided in .RecipientCertEncodedB.
This property is not available at design time.
