Hello, I need to incorporate, in a program in C, who send mail of my users, a S/MIME signature.
I've already sign, for test, a text message, and an html message, with command openssl smime -sign.. and it's ok. (without headers of course, i had them later), and I see if message have text and html part, signature is bad, so : For beginning, I've a question about this. If I've a mail, who have : - The headers (I remove them) - Content-type: text/plain - Content-type: html - Content-type: attachment (jpg for example) Is it true, for a good signature in mail, i must sign in 3 parts: text part, then html part, then attachment, and not all mail (without headers of course)? True or false? So, if it's true, in the s/mime attachment, if mail have 3 parts (text, html, 1 attachment), s/mime attachment have 3 signatures + public key? regards ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
