As dcooper16 noted in #834 there are checks which test for openssl versions
but don't take LibreSSL in account. This adds checks to it for several
LibreSSL versions (>=2.1.x) which are known to support ``determine_trust()``
and it HAS_DH_BITS.
Moreover engine check has been improved. Older LibreSSL versions (2.1 specifically)
had different error messages, so the previous checks failed. There's also
a CMD_LINE flag now where one can switch the engine support off: NO_ENGINE .
run_renogo from #834 is still an open issue.
All three issues fixed. Terminal code were actually
tow problems: Logging in from Linux with a 256 color xterm
makes tput set AF from OpenBSD hiccup. And the detection
of not-ncurses style underline e.g. was not working under OpenBSD.
The engine fix was done by David Cooper (see #831).
There's also a name of the binary now (OpenSSL/LibreSSL) for tracking
the flavor used.
SWURL contained for historical reasons trailing blanks
for released versions.
This caused an error in pr_boldurl --> html_out which
didn't write the trailing style info and didn't close
the href tag (travis complained.)
This patch removes the trailing blank but it doesn't
fix the error.
This is an initial implementation of the idea I proposed in #791. It includes checks based on draft-ietf-tls-grease as well as checks for specific implementation bugs that have previously been encountered.
This code needs testing. While I know of one server that will fail if the ClientHello contains more than 128 ciphers, I haven't been able to test any of the other code against any servers that have the tested-for bugs.
In addition, there is a need for polishing. The tests are referred to as `--grease`, which may not be a very user-friendly name. In addition, there is no output providing information about what tests are being performed. If a server fails a test, then a warning message is printed and is sent to `fileout()`. If the server passes all of the tests, then there is just a single output of "No bugs found."
At the moment, the code is not run by default. Unless `-g` or `--grease` is explicitly included in the command line, the code in this commit is not executed.
Currently the call to `$OPENSSL s_client` to obtain the certificate returned by the server when SNI is not provided is in `certificate_info()`, which means that it is called once for each certificate found the various called to `get_server_certificates()`.
This PR moves the call to `$OPENSSL s_client` to `run_server_defaults()` so that the call is made only once, even if more than one server certificate was found.
In addition, in most cases the certificate returned by the server when SNI is not provided will already have been retrieved by `run_server_defaults()` (in rounds 8-14), in which case `$HOSTCERT.nosni` can just be copied from there rather than making an additional call to `$OPENSSL s_client`.
During protocol check if a sever answered unexpected with
closing the conenction or another malformed reply the
output was not ok as DETECTED_TLS_VERSION was empty.
This fixes it by filling the variable with a string in ``parse_tls_serverhello()``
and then check in higher level (``run_protocols()``) the content.
Also it seems that I forgot in the commit from yesterday one ``&&`` to
commit in ``run_breach()``
A PR was just accepted into the master branch of https://github.com/openssl/openssl that specifies OpenSSL names for the ARIA GCM cipher suites: bc32673869. This PR adds these OpenSSL names to the cipher-mapping.txt file. It also changes the description of the encryption algorithm for these ciphers from "ARIA" to "ARIAGCM" to be consistent with OpenSSL and with the other GCM ciphers in the cipher-mapping.txt file.
In addition, OpenSSL names for some of the ARIA CBC ciphers are provided in https://github.com/openssl/openssl/blob/master/doc/man1/ciphers.pod, and this PR adds those OpenSSL names to the cipher-mapping.txt file as well.
