I have absolutly no chance to use Sign method to digitaly sign mails.
In documentation missing page pro help to Sign method...
and from your comment in source code I didn't know what files would you like to add in parameters
I have p12 certifikate and password to this...
but you require to 2 certificates and one password
at internet i found that you probably requires pem files
but it doesn't work
and it returing nonsense ... files exists and are readabile
What is the expected output? What do you see instead?
Signing Error: error:2006D080:BIO routines:BIO_new_file:no such file
What version of the product are you using? On what operating system?
