Hi there,

Please can you confirm that if I sign an email with a certificate and set TElSimpleSMIMEOptions.IncludeIssuerCertificates to True, that it will only include all the public keys and not the private key in the email.

I'm sure this is the case, but just need to know for sure.

Hello Erich,

Yes, that's right. S/MIME does not even provide technical means for transferring private keys.

There was some mechanism designed for transferring private and public keys by e-mail, and that mechanism was part of S/MIME, if memory serves, but in any case it is not implemented in SecureBlackbox, so only public keys are included.

Sincerely yours
