It is possible to generate a self-signed CA certificate (for instance for an internal CA). You need to check however that the extended capabilities say that the certificate is good for signing. Omitting this, but signing with it anyway, can on occasion produce the above error. A self-signed certificate used as the server certificate, and then adding that certificate to the trust chain will not itself normally work. -- Alex Bligh ------------------------------------------------------------------- List admin: https://cool.haxx.se/list/listinfo/curl-library Etiquette: https://curl.haxx.se/mail/etiquette.html
