Specifies which cipher suites to use in the connection if it negotiates TLS
1.3. The list of ciphers suites must specify valid ciphers. Read up on TLS 1.3

This option is currently used only when curl is built to use OpenSSL 1.1.1 or
later, or Schannel. If you are using a different SSL backend you can try
setting TLS 1.3 cipher suites by using the --ciphers option.
copyright: update all copyright lines and remove year ranges - they are mostly pointless in all major jurisdictions - many big corporations and projects already don't use them - saves us from pointless churn - git keeps history for us - the year range is kept in COPYING checksrc is updated to allow non-year using copyright statements Closes #10205 2023-01-02 20:51:48 +08:00			`c: Copyright (C) Daniel Stenberg, <daniel@haxx.se>, et al.`
docs/cmdline-opts: add copyright and license identifier to each file gen.pl now insists on C: and SPDX-License-Identifier: fields to be present in all files. Closes #9002 2022-06-14 06:12:03 +08:00			`SPDX-License-Identifier: curl`
setopt: add TLS 1.3 ciphersuites Adds CURLOPT_TLS13_CIPHERS and CURLOPT_PROXY_TLS13_CIPHERS. curl: added --tls13-ciphers and --proxy-tls13-ciphers Fixes #2435 Reported-by: zzq1015 on github Closes #2607 2018-05-29 22:12:52 +08:00			`Long: tls13-ciphers`

docs: add categories to all cmdline opts Adapted gen.pl with 'listcats' This commit is a part of "--help me if you can" Closes #5680 2020-07-13 20:15:04 +08:00			`Category: tls`
curl.1: provide examples for each option The file format for each option now features a "Example:" header that can provide one or more examples that get rendered appropriately in the output. All options MUST have at least one example or gen.pl complains at build-time. This fix also does a few other minor format and consistency cleanups. Closes #7654 2021-08-31 22:37:14 +08:00			`Example: --tls13-ciphers TLS_AES_128_GCM_SHA256 $URL`
cmdline-opts: made the 'Added:' field mandatory Since "too old" versions are no longer included in the generated man page, this field is now mandatory so that it won't be forgotten and then not included in the documentation. Closes #7786 2021-09-28 17:50:07 +08:00			`Added: 7.61.0`
docs: provide more see also for cipher options More cross references. Hide nroff errors. Closes #11513 2023-07-25 16:28:18 +08:00			`See-also: ciphers curves proxy-tls13-ciphers`
cmdline/docs: add a required 'multi' keyword for each option The keyword specifies how option works when specified multiple times: - single: the last provided value replaces the earlier ones - append: it supports being provided multiple times - boolean: on/off values - mutex: flag-like option that disable anoter flag The 'gen.pl' script then outputs the proper and unified language for each option's multi-use behavior in the generated man page. The multi: header is requires in each .d file and will cause build error if missing or set to an unknown value. Closes #9759 2022-10-18 16:39:43 +08:00			`Multi: single`

schannel: fix user-set legacy algorithms in Windows 10 & 11 - If the user set a legacy algorithm list (CURLOPT_SSL_CIPHER_LIST) then use the SCHANNEL_CRED legacy structure to pass the list to Schannel. - If the user set both a legacy algorithm list and a TLS 1.3 cipher list then abort. Although MS doesn't document it, Schannel will not negotiate TLS 1.3 when SCHANNEL_CRED is used. That means setting a legacy algorithm list limits the user to earlier versions of TLS. Prior to this change, since 8beff435 (precedes 7.85.0), libcurl would ignore legacy algorithms in Windows 10 1809 and later.
