As noted in #1605 the brotli compression check was missing. So hosts
which didn't offer gzip deflate or compress but brotli seemed to
be fine but they shoould have been labled as potentially VULNERABLE.
This also fixes a bug: The HTTP header returned was only checking
for case-sensitive "Content-Encoding". RFC 2616 states in 4.2
(Message Headers): "Field names are case-insensitive"
This commit fixes#1551 in the 3.0 branch by changing get_cipher() to recognize RFC names that begin with SSL_*. It also modifies run_beast() so that it does not get stuck in an infinite loop if get_cipher() doesn't return a valid cipher name.
.. as it may not be available everywhere, see #1521 (NixOS).
This commit replaces all instances from pwd or /bin/pwd by $PWD.
It is a bash internal and the fastest. Also it added some quotes
to PWD a it may contain white spaces in the future (currently
there's a check for it that it won't)
This commit addresses two bugs: #1506 and #1508.
First, the variable rDNS can contain multiple lines due to multiple PTR DNS
records, though this is not recommended. In those cases the multiple PTR DNS
were concatenated on the screen, without any blank.
Secondly - depending on the name server entries and on the output of the DNS
binaries used it can contain non-printable characters or characters which are
printable but later on interpreted on the output device (\032 was mentioned
in #1506) which on the screen was interpreted as octal 32 (decimal 26 = ▒,
try echo "\032"), so basically a terminal escape sequence was smuggled
from the DNS server to the screen of the users. In JSON pretty output we
had also this escape sequence which was fine for jsonlint but caused jq
to hiccup.
Fix: we use a loop to check for each FQDN returned. There we remove chars which
under those circumstances can show up. The blacklist is taken from RFC 1912
("Allowable characters in a label for a host name are only ASCII, letters, digits,
and the `-' character").
Hostnames can contain a trailing dot (and sometimes they should).
If they are supplied to testssl.sh however they will be also interpreted
as a URL PATH when the servive is HTTP.
This commit fixes that.

This switch had no effect. There was probably a regression
problem as it worked before.
Besides fixing that the large case statement in parse_cmd_line()
was simplified, in a sense that banner and help functions were
moved to a separate case statement.
