(Editors note: I would read over this code carefully, since the user who provided this patch is not the creator. --bri ) (Additionally, this patch does not include the proper licensing information. At least the following is in order: 6. Redistributions of any form whatsoever must retain the following acknowledgment: "This product includes software developed by Ralf S. Engelschall for use in the mod_ssl project (http://www.modssl.org/)." Anyway, back to the patch info. --bri ) Here is a patch that will allow you to add a certificate chain by specifying a pem file with a -Q option. This borrows code from mod_ssl, I didn't write this, I found it on some message board and forget the name of the author. It should patch stunnel 3.13 without any problems besides offsets. -Jon
