This was causing us to use the TLS settings from one server on another
which is not always appropriate. Instead, we now treat it like other
connection information and do not copy it. We get the TLS settings later
as appropriate when connecting.
Note there is still probably more that could be cleaned up here. For
example, the unix socket might be better treated as connection info too.
Fixes#1027.
This patch adds two new options to /CONNECT and /SERVER to let the user
pin either an x509 certificate and/or the public key of a given server.
It is possible to fetch the certificate outside of Irssi itself to
verify the checksum. To fetch the certificate call:
$ openssl s_client -connect chat.freenode.net:6697 < /dev/null 2>/dev/null | \
openssl x509 > freenode.cert
This will download chat.freenode.net:6697's TLS certificate and put it into the
file freenode.cert.
-tls_pinned_cert
----------------
This option allows you to specify the SHA-256 hash of the x509
certificate. When succesfully connected to the server, irssi will verify
that the given server certificate matches the pin set by the user.
The SHA-256 hash of a given certificate can be verified outside of irssi
using the OpenSSL command line tool:
$ openssl x509 -in freenode.cert -fingerprint -sha256 -noout
-tls_pinned_pubkey
------------------
This option allows you to specify the SHA-256 hash of the subject public key
information section of the server certificate. This section contains both the
cryptographic parameters for the public key, but also information about the
algorithm used together with the public key parameters.
When succesfully connected to the server, irssi will verify that the
given public key matches the pin set by the user.
The SHA-256 hash of a public key can be verified outside of irssi using
the OpenSSL command line tool:
$ openssl x509 -in freenode.cert -pubkey -noout | \
openssl pkey -pubin -outform der | \
openssl dgst -sha256 -c | \
tr a-z A-Z
It is possible to specify both -tls_pinned_cert and -tls_pinned_pubkey
together.
This patch changes the internal name of SSL to TLS. We also add -tls_*
options to /CONNECT and /SERVER, but make sure that the -ssl_* versions
of the commands continue to work like before.
this adds the CONFIG_REC * to the config_node_section and
config_node_section_index APIs as they will require access to the config
cache later on to make the config parser more robust.
