| + | certificate_list | ||
| + | This is a sequence (chain) of X.509v3 certificates. | ||
| + | certificate must come first in the list. Each following | ||
| + | certificate must directly certify the one preceding it. Because | ||
| + | certificate validation requires that root keys be distributed | ||
| + | independently, | ||
| + | certificate authority may optionally be omitted from the chain, | ||
| + | under the assumption that the remote end must already possess it | ||
| + | in order to validate it in any case. | ||
| + | </ | ||
| + | |||
| + | |||
| + | It is required to put not only site certificate in your web server configuration, | ||
| + | If your server certificate is in PEM format (text), additional certificates can be simply concatenated. | ||
| + | All certificates should be in correct order. | ||
