@ -288,33 +288,29 @@ How do I generate an `sslcacertfile` file?
The `sslcacertfile` file must contain an SSL certificate (or a concatenated
certificates chain) in PEM format. (See the documentation of
`ssl.wrap_socket`_'s `certfile` parameter for the gory details.) The following
command should generate a file in the proper format::
`ssl.wrap_socket`_'s `certfile` parameter for the gory details.) You can use either openssl or gnutls to create a certificate file in the required format.
#. via openssl::
openssl s_client -CApath /etc/ssl/certs -connect ${hostname}:imaps -showcerts \
| perl -ne 'print if /BEGIN/../END/; print STDERR if /return/' > $sslcacertfile
^D
Before using the resulting file, ensure that openssl verified the certificate
successfully.
#. via gnutls::
gnutls-cli --print-cert -p imaps ${host} </dev/null | sed -n \
| '/^-----BEGIN CERT/,/^-----END CERT/p' > $sslcacertfile
The path `/etc/ssl/certs` is not standardized; your system may store
SSL certificates elsewhere. (On some systems it may be in
`/usr/local/share/certs/`.)
If this does not work and you are getting error messages, you can test the certificate using a command like (credits to Daniel Shahaf for this)::
Before using the resulting file, ensure that openssl verified the certificate
successfully. In case of problems, you can test the certificate using a command such as (credits to Daniel Shahaf for this) to verify the certificate::
% openssl s_client -CAfile $sslcacertfile -connect ${hostname}:imaps 2>&1 </dev/null
verify return:1
verify return:1
(If you post the output, post the full output, without 'grep' filtering)
verify return:1
Verify return code: 0 (ok)
If the server uses STARTTLS, pass the -starttls option and the 'imap' port.
Also, you can test::
Also, you can test using gnutls::
gnutls-cli --x509cafile certs/mail.mydomain.eu.cert -p 993 mail.mydomain.eu
