This trick works only in system filters, where the commands are obeyed
to enable my clients to use TLS. However, clients other than Exim
refuse to accept this certificate. What's wrong?
-A1701: It seems that some clients require that the certificate presented by
- the server be a user (also called ``leaf'' or ``site'') certificate, and not
- a self-signed certificate. In this situation, the self-signed
- certificate must be installed on the client as a trusted root
- \*certification authority*\ (CA), and the certificate used by the server
- must be a user certificate signed with that self-signed certificate.
+A1701: Don't use a self-signed certificate today. Use a certificate from a
+ certificate authority, whether your own private certificate authority or
+ a free CA such as Let's Encrypt.
- For information on creating self-signed CA certificates and using them
- to sign user certificates, see the \*General implementation overview*\
- chapter of the Open-source PKI book, available online at
- \?http://ospkibook.sourceforge.net/?\. Here is a quick overview. First,
- read this message:
-
- \?http://www.FreeBSD.org/cgi/mid.cgi?id=3C3F3A93.C1ECF9B0%40mindspring.com?\
-
- Then, follow the instructions found on these two (consecutive) pages:
-
- \?http://ospkibook.sourceforge.net/docs/OSPKI-2.4.6/OSPKI/initialisation.htm?\
- \?http://ospkibook.sourceforge.net/docs/OSPKI-2.4.6/OSPKI/keygensign.htm?\
-
- Two points on the PKI Book literature:
-
- (1) It's assumed that it's okay to use a passphrase-protected key to
- encrypt the user/site/leaf certificate. If this isn't acceptable,
- you seem to be able to strip out the passphrase as follows:
-
-==> openssl rsa -in user.key -our user.key.new
- mv user.key.new
-
- This should be done immediately after \(user.key)\ is created.
-
- (2) The \*sign.sh*\ script is available in the \*mod_ssl*\ distribution,
- available at \?http://www.modssl.org/source/?\.
-
- Having followed the instructions, you end up with the following files:
-
- (a) \(ca.crt)\
-
- This file should be installed into the client software as a trusted
- root certification authority. In Windows XP, this can be done as follows:
-
- \#\#Call the file \(ca_cert.cer)\
- [[br]]
- \#\#Double-click on the file
- [[br]]
- \#\#"Install Certificate";
- [[br]]
- \#\#"Next"
- [[br]]
- \#\#"Place all certificates in the following store"
- [[br]]
- \#\#"Browse..."
- [[br]]
- \#\#"Trusted Root Certification Authorities"
- [[br]]
- \#\#"OK"
- [[br]]
- \#\#"Next"
- [[br]]
- \#\#"Finish"
- [[br]]
- \#\#"Yes"
- [[br]]
- \#\#"OK"
-
- (b) \(user.crt)\ and \(user.key)\
-
- These files should be installed into the server software. In Exim, this
- can be done by adding these lines to the configuration file:
-
-==> tls_certificate = /usr/local/etc/exim/tls_cert
- tls_privatekey = /usr/local/etc/exim/tls_key
-
- Then install \(user.crt)\ and \(user.key)\ under the names \(tls_cert)\
- and \(tls_key)\ in the appropriate directory.
+ The exim.org setup uses Let's Encrypt, using the lego tooling and a small
+ shell wrapper to let the certificates be automatically renewed via cron.
