Committed, thanks for the patch.

And I refactorized the gnutls callback to display certificates, even if the new server option "ssl_fingerprint" is set.

Task 12293 is also related. It proposes an alternative method to accept certificates.

Task #11357 is also related. It requests a per-network root CA list. But with this option, it does become less important. It seems to me that if you're going to set a network specific CA, you might as well just specify exactly which certificate to accept. But I might be wrong.

Uploaded a patch that adds a 'ssl_fingerprint' option for servers. When non-empty, the normal checks are disabled and the certificate fingerprint must match the set sha1 fingerprint. It should be given as hexadecimal string withouth seperators between the bytes. That's also what weechat shows when it rejects the certificate.

We could still maybe add a message when the certificate is rejected that the user can accept it by setting this option.

I thought this was easier than the gnutls builtin trusted keystore, since it can be managed from weechat with simple set/unset commands.

This is my first patch for weechat, so I hope it's good enough :)

By the way there is also a GnuTLS feature which directly implements something very similar to this, called TOFU (Trust On First Use): http://www.gnutls.org/manual/html_node/Verifying-a-certificate-using-trust-on-first-use-authentication.html#Verifying-a-certificate-using-trust-on-first-use-authentication

Options for the sha1 fingerprint and/or the path to the expected ssl-certificate for a connection.
