When a TLS server requests a client certificate during handshake and
none can be provided, libcurl now returns this new error code
CURLE_SSL_CLIENTCERT
Only supported by Secure Transport and OpenSSL for TLS 1.3 so far.
Closes#6721
wording taken from man page for CURLOPT_URL.3
As far as I can see, the URL part is either malloc'ed before due to
encoding or it is strdup'ed.
Closes#6953
configure no longer tries to find a TLS library by default, but all
libraries are now equal: the user needs to explicitly ask what TLS
library or libraries to use.
If no TLS library is selected, configure will error out unless
--without-ssl is explicitly used to request a built without TLS (as that
is very rare these days).
Removes: --with-winssl, --with-darwinssl and all --without-* options for
TLS libraries.
Closes#6897
- Disable auto credentials by default. This is a breaking change
for clients that are using it, wittingly or not.
- New libcurl ssl option value CURLSSLOPT_AUTO_CLIENT_CERT tells libcurl
to automatically locate and use a client certificate for
authentication, when requested by the server.
- New curl tool options --ssl-auto-client-cert and
--proxy-ssl-auto-client-cert map to CURLSSLOPT_AUTO_CLIENT_CERT.
This option is only supported for Schannel (the native Windows SSL
library). Prior to this change Schannel would, with no notification to
the client, attempt to locate a client certificate and send it to the
server, when requested by the server. Since the server can request any
certificate that supports client authentication in the OS certificate
store it could be a privacy violation and unexpected.

A struct bufref holds a buffer pointer, a data size and a destructor.
When freed or its contents are changed, the previous buffer is implicitly
released by the associated destructor. The data size, although not used
internally, allows binary data support.
A unit test checks its handling methods: test 1661
Closes#6654
... previously they were supported if a TLS library would (unexpectedly)
still support them, but from this change they will be refused already in
curl_easy_setopt(). SSLv2 and SSLv3 have been known to be insecure for
many years now.
Closes#6773
Instead output a warning about it and continue with the defaults.
These SSL versions are typically not supported by the TLS libraries since a
long time back already since they are inherently insecure and broken. Asking
for them to be used will just cause an error to be returned slightly later.
In the unlikely event that a user's TLS library actually still supports these
protocol versions, this change might make the request a little less insecure.

In ngtcp2 the `with-gnutls` option is disabled by default, which will

- Add description: Explain that some options aren't inherited because
they are not relevant for the DoH SSL connections or may result in
unexpected behavior.
- Remove the reference to #4578 (SSL verify options not inherited) since
that was fixed by #6597 (separate DoH-specific options for verify).
- Explain that DoH-specific options (those created by #6597) are
available: CURLOPT_DOH_SSL_VERIFYHOST, CURLOPT_DOH_SSL_VERIFYPEER and
CURLOPT_DOH_SSL_VERIFYSTATUS.
- Add a reference to #6605 and explain that the user's debug function is
not inherited because it would be unexpected to pass internal handles
(ie DoH handles) to the user's callback.

This also pins a specific release in the Travis test so future
API-breaking changins in crustls won't break curl builds.
Add RUSTLS documentation to release tarball.
Enable running tests for rustls, minus FTP tests (require
connect_blocking, which rustls doesn't implement) and 313 (requires CRL
handling).
Closes#6763
- Document in DOH that some SSL settings are inherited but DOH hostname
and peer verification are not and are controlled separately.
- Document that CURLOPT_SSL_CTX_FUNCTION is inherited by DOH handles but
we're considering changing behavior to no longer inherit it. Request
feedback.

- New libcurl options CURLOPT_DOH_SSL_VERIFYHOST,
CURLOPT_DOH_SSL_VERIFYPEER and CURLOPT_DOH_SSL_VERIFYSTATUS do the
same as their respective counterparts.
- New curl tool options --doh-insecure and --doh-cert-status do the same
as their respective counterparts.
Prior to this change DOH SSL certificate verification settings for
verifyhost and verifypeer were supposed to be inherited respectively
from CURLOPT_SSL_VERIFYHOST and CURLOPT_SSL_VERIFYPEER, but due to a bug
were not. As a result DOH verification remained at the default, ie
enabled, and it was not possible to disable. This commit changes
behavior so that the DOH verification settings are independent and not
inherited.

- Deduplicate the logic used by write-out and write-out json.
Rather than have separate writeLong, writeString, etc, logic for
each of write-out and write-out json instead have respective shared
functions that can output either format and a 'use_json' parameter to
indicate whether it is json that is output.
This will make it easier to maintain. Rather than have to go through
two sets of logic now we only have to go through one.
- Support write-out %{errormsg} and %{exitcode} in json.
- Clarify in the doc that %{exitcode} is the exit code of the transfer.
Prior to this change it just said "The numerical exitcode" which
implies it's the exit code of the tool, and it's not necessarily that.

The script warns if the length of $opt and $desc is > 78. However, these

Also the $bitmask field is totally forgotten. Currently this leads to
