In OpenSSL 1.1, a failure to negotiate a protocol is a fatal error, so
fork that test. This also popped up an issue where we assumed all errors
had library, function, and reason strings which is not necessarily the
case.
While we're in here, adjust the Display impl to match what OpenSSL
prints out.
Closes#465
This commit is relatively major refactoring of the `openssl-sys` crate as well
as the `openssl` crate itself. The end goal here was to support OpenSSL 1.1.0,
and lots of other various tweaks happened along the way. The major new features
are:
* OpenSSL 1.1.0 is supported
* OpenSSL 0.9.8 is no longer supported (aka all OSX users by default)
* All FFI bindings are verified with the `ctest` crate (same way as the `libc`
crate)
* CI matrixes are vastly expanded to include 32/64 of all platforms, more
OpenSSL version coverage, as well as ARM coverage on Linux
* The `c_helpers` module is completely removed along with the `gcc` dependency.
* The `openssl-sys` build script was completely rewritten
* Now uses `OPENSSL_DIR` to find the installation, not include/lib env vars.
* Better error messages for mismatched versions.
* Better error messages for failing to find OpenSSL on a platform (more can be
done here)
* Probing of OpenSSL build-time configuration to inform the API of the `*-sys`
crate.
* Many Cargo features have been removed as they're now enabled by default.
As this is a breaking change to both the `openssl` and `openssl-sys` crates this
will necessitate a major version bump of both. There's still a few more API
questions remaining but let's hash that out on a PR!
Closes#452
SSL_CTX_add_extra_chain_cert assumes ownership of the certificate, so
the method really needs to take an X509 by value. Work around this by
manually cloning the cert.
This method has been around for over a year but I'm guessing nobody
actually used it since it produces a nice double free into segfault!
Allows recognizing when a stream is still in handshake mode and can gracefully
transition when ready. The blocking usage of the API should still be the same,
just helps nonblocking implementations!
1DES is well and truly dead for actual sensitive information, (its
keysize is too small for modern purposes), but it can still find use in
backwards compatiblity or educational applications.
`EVP_PKEY_get1_RSA` returns a RSA structure with its reference count
increased by 1 and therefore we need to call `RSA_free` after finishing
using that value.
SSL_CTX_use_certificate_chain_file() is preferred over
SSL_CTX_use_certificate_file().
It allows the use of complete certificate chains instead of loading
only the first certificate in a PEM file.
The current behavior causes a server written using rust-openssl to (if
it cannot negotiate a protocol) fallback to the first protocol it has
avaliable.
This makes it impossible to detect protocol mismatches.
This updates our selection to be more similar to how openssl's
s_server behaves: non-matching protocols are not supplied with a
fallback.
Note that some setups may actually want a fallback protocol supplied
via ALPN. To support those cases, we should consider adding a generic
callback that allows protocol selection to be entirely controlled by
the programmer.
For the purposes of having a sane default, however, not supplying a
default (and mimicing s_server's behavior) is the best choice.
rust-openssl didn't support forward secrecy at all.
This adds support for DHE, by exposing set_tmp_dh() as well as the RFC5114
parameters, which are conveniently exposed since OpenSSL 1.0.2.
With OpenSSL >= 1.0.2, and the rfc5114 feature gate, enabling DHE is as simple
as (here for 2048-bit MODP group with 256-bit prime order subgroup):
use openssl::dh::DH;
let dh = DH::get_2048_256().unwrap();
ctx.set_tmp_dh(dh).unwrap();
With OpenSSL < 1.0.2, DH::from_params() can be used to manually specify the
DH parameters (here for 2048-bit MODP group with 256-bit prime order subgroup):
use openssl::bn::BigNum;
use openssl::dh::DH;
