2017-09-11Restore compatibility with old OpenSSL versionsLemonBoy
Let's implement X509_STORE_up_ref on our own.
2017-09-11Increment the X509_STORE refcount during the connectionLemonBoy
OpenSSL doesn't increment the reference count when the store is assigned to a SSL_CTX.
2017-08-10Don't error out on failure to load default certificate store.Edward Tomasz Napierala
This restores the previous behaviour. Signed-off-by: Edward Tomasz Napierala <trasz@FreeBSD.org>

2017-02-03Support OpenSSL 1.1.0.LemonBoy
- X509_get_notBefore becomes X509_get0_notBefore - X509_get_notAfter becomes X509_get0_notAfter - ASN1_STRING_data becomes ASN1_STRING_get0_data (and drops the const) - The whole library is now initialized by OPENSSL_init_ssl Closes #597
2017-01-22Check whether the client certificate is expired.LemonBoy
Right now we only warn the user, the connection keeps going. Fixes #211
2017-01-06Add OPENSSL_NO_EC for solaris 11.3, see issue #598dequis
Original patch by 'Slarky' According to that ticket, the next major version of solaris won't need this. Consider reverting this when solaris 11.3 stops being relevant.
2016-10-22Kill do { ... } while (0); and replace it with goto's.Alexander Færøy
2016-10-22Emit the TLS handshake finished signal before we do verification.Alexander Færøy
This patch moves the emitted "tls handshake finished" signal to before we do validation of the given TLS certificate. This ensures that we display certificate information before we possibly error out and disconnects from the server.
2016-10-22Kill support for DANE.Alexander Færøy
This patch removes support for DANE validation of TLS certificates. There wasn't enough support in the IRC community to push for this on the majority of bigger IRC networks. If you believe this should be reintroduced into irssi, then please come up with an implementation that does not rely on the libval library. It is causing a lot of troubles for our downstream maintainers.

2016-10-22Add x509 certificate and public key pinning support.Alexander Færøy
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.

2016-10-22Populate and emit TLS_REC after TLS handshake have completed.Alexander Færøy
2016-10-22Rename SSL to TLS.Alexander Færøy
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.
2016-10-16Always build irssi with TLS support.Alexander Færøy
This patch removes the optional checks for whether to build irssi with TLS support or not. This will allow us to ship a default configuration file where we connect to TLS enabled IRC servers out of the box.
2016-03-13Add clear error calls to irssi_ssl_get_iochannelWill Storey
2016-03-13Clear error queue before SSL I/O operationsWill Storey
Otherwise we can see errors that are not related to the operation we check for. SSL_get_error() inspects the thread's error queue. See https://www.openssl.org/docs/manmaster/ssl/SSL_get_error.html for more information.
