* Added support for TLS Keying Material Exporters [RFC-5705]Daniel Kubec2015-10-101-0/+33
| | | | | | | | | | | | | Keying Material Exporter [RFC-5705] allow additional keying material to be derived from existing TLS channel.

* openssl: be less verbose about cipher translation errorsSteffan Karger2015-10-081-1/+1
| | | | | | | | | | | | | | | Translation errors are usually not a real problem, since we don't maintain the complete list of ciphers OpenSSL supports. So, be less verbose if we can not find a translation. Also, add 'translations' for commonly used negated cipher suites to suppress messages about those completely.

* Improve --tls-cipher and --show-tls man page descriptionSteffan Karger2015-05-091-1/+1
| | | | | | | | | | | | | | As reported in trac tickets #304, #358 and #359 (and possibly more), the usage and interpretation of --tls-cipher (and --show-tls) is tricky. This patch extends the man page to explain those a bit better and point out that --tls-cipher is an expert feature (i.e. easy to get wrong). Also add a notice to the --show-tls output, referring to the man page explanation.

* Disable SSL compressionSteffan Karger2015-02-151-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | As reported in trac #502, SSL compression can cause problems in some corner cases. OpenVPN does not need SSL compression, since the control channel is low bandwidth. This does not influence the data channel compressen (i.e. --comp or --comp-lzo). Even though this has not yet been relevant for OpenVPN (since an attacker can not easily control contents of control channel messages), SSL compression has been used in the CRIME and BREACH attacks on TLS. TLS 1.3 will probably even remove support for compression all together, for exactly this reason. Since we don't need it, and SSL compression causes issues, let's just disable it in OpenSSL builds. PolarSSL has no run-time flag to disable compression, but is by default compiled without compression.

* Add option to disable Diffie Hellman key exchange by setting '--dh none'Steffan Karger2015-01-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As requested on the mailing list and in trac ticket #410, add an option to disable 'traditional' Diffie Hellman key exchange. People want to be able to create ecdh-only configurations. This patch also disables RSA key exchange by default for OpenSSL builds, to prevent that people who set "--dh none" but have an OpenSSL version that doesn't support ECDH end up with a less secure connection. Note that users that specify their own --tls-cipher override these defaults and thus can still use whatever OpenSSL supports (and might thus end up with less secure connections). PolarSSL does not allow to easily disable RSA key exchange during runtime, but its default compile options do not include RSA key exchange based cipher suites. Finally update the manpage to reflect the new behaviour, and while touching it change the text to motivate users towards a more secure configuration. v2 - disable RSA key exchange by default Signed-off-by: Steffan Karger <steffan@karger.me> Acked-by: Arne Schwabe <arne@rfc2549.org> Message-Id: <1420141569-11773-1-git-send-email-steffan@karger.me> URL: http://article.gmane.org/gmane.network.openvpn.devel/9376 Signed-off-by: Gert Doering <gert@greenie.muc.de>

This does not remove to runtime option to run without SSL, just the compile time option to not include any SSL-related code.

* Don't issue warning for 'translate to self' tls-ciphersSteffan Karger2014-07-071-1/+2
| | | | | | | | | | | | | | | | | All cipher suite names supplied through --tls-cipher are translated by OpenVPN to IANA names, to get OpenSSL and PolarSSL configuration files compatible. OpenSSL however supports cipher suite group names, like 'DEFAULT', 'HIGH', or 'ECDH'. To make OpenVPN not complain about these, entries translating these to themselves were added to the translation table. However, to make OpenVPN not still complain, the deprecated-name check has to be reversed from 'if this is a deprecated name then complain' to 'if this is not a iana name, then complain'. Which this commit does.

* Add support for elliptic curve diffie-hellmann key exchange (ECDH)Steffan Karger2014-04-251-0/+119
| | | | | | | | | | | | | | | | | | | | | | | | This patch is based on Jan Just Keijser's patch from Feb 7, 2012. When OpenSSL 1.0.2+ or PolarSSL is used, lets the crypto library do the heavy lifting. For OpenSSL builds, if a user specifies a curve using --ecdh-curve, it first tries to override automatic selection using that curve. For older OpenSSL, tries the following things (in order of preference): * When supplied, use the ecdh curve specified by the user. * Try to extract the curve from the private key, use the same curve. * Fall back on secp384r1 curve. Note that although a curve lookup might succeed, OpenSSL 1.0.0 and older do *not* support TLSv1.1 or TLSv1.2, which means no that no EC-crypto can be used.

* Remove OpenSSL tmp_rsa_callback. Removes support for ephemeral RSA in TLS.Steffan Karger2014-01-031-18/+0
| | | | | | | | | | | | | | | | | | | | | This code would not really generate ephemeral keys every time it is called, but a single key that would be reused during process lifetime and returned each time the function was called; probably not what users would expect. TLS allowes ephemeral keys to be used only when no other key exchange, such as (ephemeral) Diffie-Hellman, is performed. The end result is that it was only used by a number of (weak) export ciphers, which could give users a false sense of security. So, instead of fixing a weak cipher mode, we'll just remove support for it completely. Plenty of better alternatives are available in TLS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | OpenSSL's tls_ctx_load_cert_file() had a parameter in which a copy of the context's certificate chain was stored on return, used by tls_ctx_use_external_private_key() only and free()d immediately thereafter. PolarSSL also supported this output parameter, but returned a pointer to the context's certificate chain (rather than to a copy of the certificate, as OpenSSL does) - which meant that we would have to #ifdef the free(). PolarSSL cannot make a copy of a certificate chain, and OpenSSL cannot store a pointer to (instead of a copy of) the cert. So remove the output parameter from tls_ctx_load_cert_file() and incorporate the needed functionality directly into tls_ctx_use_external_private_key() (which is straightforward for both OpenSSL and PolarSSL, as long as you don't try to support both at once.)

Without this patch, they were ignored completely - with this patch, they're loaded in the extra certs chain which makes them available for chain verification but still does not make them trusted if --ca is set.

* TLS version negotiationJames Yonan2013-07-111-3/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updated the TLS negotiation logic to adaptively try to connect using the highest TLS version supported by both client and server. Previously, OpenVPN (when linked with OpenSSL) would always connect using TLS 1.0. Also added tls-version-min directive to force a higher TLS version than 1.0: tls-version-min <version> ['or-highest'] -- sets the minimum TLS version we will accept from the peer. Examples for version include "1.0" (default), "1.1", or "1.2". If 'or-highest' is specified and version is not recognized, we will only accept the highest TLS version supported by the local SSL implementation. Examples: tls-version-min 1.1 -- fail the connection unless peer can connect at TLS 1.1 or higher. tls-version-min 1.2 or-highest -- require that the peer connect at TLS 1.2 or higher, however if the local SSL implementation doesn't support TLS 1.2 (as it wouldn't if linked with an older version of OpenSSL), reduce the minimum required version to the highest version supported by the local SSL implementation (such as TLS 1.0). This is intended to allow client configurations to target higher TLS versions that are supported on the server, even if some older clients don't support these versions yet.

* Use constrain_int() instead of MIN()+syshead.c compat definition - v2.Gert Doering2013-05-071-1/+1
| | | | | | | | | | | | | | Reverts commit 15ca5c297b556fbb, instead change ssl_openssl.c to use "constrain_int()", which already exists in "integer.h". Using this instead of min_int() ensures that the result is always bounded to 0...256 even in the case of a potential MAX_INT overflow.
