Add support for signing outgoing HTTP requests per RFC 9421 using
Ed25519 or HMAC-SHA256 algorithms.
New libcurl options:
- CURLOPT_HTTPSIG: signing algorithm ("ed25519" or "hmac-sha256")
- CURLOPT_HTTPSIG_KEY: path to hex-encoded key file
- CURLOPT_HTTPSIG_KEYID: key identifier for Signature-Input
- CURLOPT_HTTPSIG_HEADERS: space-separated components to sign
New CLI flags: --httpsig, --httpsig-key, --httpsig-keyid,
--httpsig-headers
The crypto layer follows the sha256.c multi-backend pattern with
implementations for OpenSSL (EVP_DigestSign) and wolfSSL
(wc_ed25519_sign_msg). HMAC-SHA256 uses the existing Curl_hmacit()
infrastructure which works on all backends.

Closes#22386Closes#21239
- asyn-thrdd.c: scope an include.
- apply more clang-format suggestions.
- tidy-up PP guard comments.
- delete empty line from the top of headers.
- add empty line after `curl_setup.h` include where missing.
- fix indent.
- CODE_STYLE.md: add `strcpy`.
Follow-up to 8636ad55df#20088
- lib1901.c: drop unnecessary line.
Follow-up to 436e67f65b#20076Closes#20070
- curl_range: replace `sendf.h` with direct header dependency
`curl_trc.h`.
- drop `curl/curl.h` includes from internal sourcees in favor of the
include made from `curl_setup.h`. Replace it with the latter where
it's the only include.
- include `curl_setup.h` before using macros, where missing.
- drop redundant `stdlib.h`, `string.h` includes, in favor of
`curl_setup_once.h` including them.
- drop redundant `limits.h` in favor of `curl_setup.h` including it.
- fake_addrinfo.h: fix typo in comment.
- curl_setup_once.h: drop `stdio.h` in favor of earlier include in
`curl_setup.h`.
- drop stray, unused, `stddef.h` includes.
- memdebug.h: add missing `stddef.h` include. (relying on accidental
includes via other headers before this patch.)
- stddef.h: document why it's included.
- strerr: drop `curl/mprintf.h` in favor of `curl/curl.h` including it
via `curl_setup.h`.
Closes#20027
Already used in `vtls.h`. Prefer this curl-namespaced name over the
unprefixed `SHA256_DIGEST_LENGTH`. The latter is also defined by TLS
backends with a potential to cause issues.
Also stop relying on externel headers setting this constant. It's
already defined in `vtls.h` on curl's behalf, do this also for `lib`.
Cherry-picked from #14495Closes#14513
- 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
Add licensing and copyright information for all files in this repository. This
either happens in the file itself as a comment header or in the file
`.reuse/dep5`.
This commit also adds a Github workflow to check pull requests and adapts
copyright.pl to the changes.
Closes#8869
put all #include of openssl files behind wolfssl ifdefs so that we can
use the wolfssl/ prefixed include paths. Without these curl only builds
when wolfssl is built with enable-all.
Fixes#8292Closes#8315
Prior to this commit, OpenSSL could be used for all these functions, but
not wolfSSL. This commit makes it so wolfSSL will be used if USE_WOLFSSL
is defined.
Closes#7806
It seems current hmac implementation use md5 for the hash,
V4 signature require sha256, so I've added the needed struct in
this commit.
I've added the functions that do the hmac in v4 signature file
as a static function ,in the next patch of the serie,
because it's used only by this file.
