| #pragma section-numbers 2 = CA Certificates = About Mercurial's handling of SSL certificates for `https` urls. <<TableOfContents>> == Changes in Mercurial 1.7.x == Mercurial has improved its https support in the 1.7.x series. When connecting to an https server, it will now verify the server's certificate. Connections to a server with the wrong identity will be rejected. As of 1.7.3, Mercurial will warn if it doesn't know how to verify it because no Certification Authorities (CAs) have been configured. {i} The "certificate not verified" warning does not mean that you are less secure than before. It just informs you how insecure you always has been. You should fix your setup so you get the security you might expect from SSL and don't get any warnings; otherwise you might just as well stop using https. == Configuration of HTTPS certificate authorities == Most operating systems maintain a set of root certificates that you might decide to trust. Note that any of these authorities can approve any server identity, and any of them will thus be able to spoof any server identity. On Debian and Ubuntu you can use this global configuration: {{{ [web] cacerts = /etc/ssl/certs/ca-certificates.crt }}} On Fedora and RHEL you can use this global configuration: {{{ [web] cacerts = /etc/pki/tls/certs/ca-bundle.crt }}} If your platform doesn't provide a usable CA list you can download a cacert file from http://curl.haxx.se/docs/caextract.html . {i} The Windows installers for Mercurial 1.7.3 (and corresponding TortoiseHg installers) contains a `cacert.pem` and will by default configure `web.cacerts` in `hgrc.d\paths.rc` and will thus prevent connecting to repositories with self-signed certificates. You might want to tweak your cacert file, for examply by removing CAs you don't trust or by adding your own internal or self-signed CAs. Only one cacerts file can be specified at any time, so you might want to override `web.cacerts` in your user or repository configuration. == Per-repository configuration == If you want to control explicitly which servers you will authenticate to and pull from you can explicitly configure the trusted servers identity for each local clone. The server's public identity can for example be retrieved with Firefox. Browse to `https://server/repo`, click the lock symbol in the lower right corner, View Certificate, Details, Export, "X.509 Certificate (PEM)" and save somewhere as `server.pem`. Other browsers have similar functionality but might call it Base64-encoded ASCII and use `.CER` or `.crt` extension, depending on the platform. {i} Including a certificate in cacerts generally means that it should be trusted, independent of its certificate chain. It generally doesn't matter if the certificate includes the chain, but the full certificate chain is apparently needed for wildcard certificates (used by for example `googlecode.com` and `codeplex.com`). {i} It is apparently not possible to export the full certificate chain on Windows with IE or Chrome. In your local repository edit `.hg/hgrc` and add {{{ [web] cacerts = /path/to/server.pem }}} Note: This requires Mercurial 1.7.3 or later. == Packaging == Packagers are encouraged to integrate as good as possible with the platforms existing PKI, for example by distributing a `hgrc.d/cacert.rc` with configuration of `web.cacerts`. If the platform doesn't have a suitable CA list you might want to distribute your own - for example the one from cURL/Mozilla. Note however that that using a pre-configured cacert list by default will cause a regression for those who connect to servers with self-signed certificates. It should thus not be introduced in a bugfix release but wait for a major update, depending on how your update strategy is. == SMTP TLS certificates == Mercurial do currently not verify TLS certificates for smtp. == See also == * http://docs.python.org/library/ssl.html#ssl-certificates * http://curl.haxx.se/docs/sslcerts.html * http://bugs.python.org/issue1589 * http://mercurial.selenic.com/bts/issue2407 |
