Microsoft Edge is, since 2019, based on Chromium. It has a completely
identical TLS signature to Chrome's. The only difference is in the HTTP
headers. Adding support for impersonating Edge was therefore extremely
simple.
Patch generated from https://github.com/lwthiker/curl/commit/e8cd43c8ebd2624b3c635ec96b165c28f675cdf2
Add curl_easy_impersonate() API function that sets the needed options
on the curl 'easy' handle. It sets the various TLS options needed for
impersonation and the HTTP headers that the browser sends by default.
In addition, libcurl will check for the environment variable
CURL_IMPERSONATE when curl_easy_init() is called, and if it exists it
will call curl_easy_impersonate() internally. This theoretically allows
replacing an existing libcurl by setting the LD_LIBRARY_PATH and
CURL_IMPERSONATE env vars, without having to recompile the app.
In addition to the statically linked curl-impersonate binary, compile
libcurl.so for dynamic linking as well. The output file is saved at
/build/out/libcurl-impersonate.so.
Also strip the output binaries to reduce their size.
For now, support is for the Chrome build only.
Consolidate all of curl's patch files into a single file (one for each
browser). The modified curl source code is now maintained in Git (at
https://github.com/lwthiker/curl) and it is easier to just
generate the needed patch with 'git --diff'.
Building curl-impersonate with Chrome impersonation requires a different
compilation and a different set of patches which may conflict with the
Firefox impersonation. Therefore we will treat them a separate builds.
All chrome related files were moved to the chrome/ directory.
