String containing message data to be signed.

szCertList

Filename of the signer's certificate (or a string with its base64 or PEM representation) and (optionally) a list of other certificates to be included in the output, separated by semi-colons (;) Alternatively, specify a single PKCS#7 certificate chain file (.p7c/.p7b) containing the signer's certificate.

szPrivateKey

Internal representation of private key for the sender.
