MODIFYING OPENSSL SOURCE
========================
This document describes the way to add custom modifications to OpenSSL sources.
If you are adding new public functions to the custom library build, you need to
either add a prototype in one of the existing OpenSSL header files;
or provide a new header file and edit
[Configurations/unix-Makefile.tmpl](Configurations/unix-Makefile.tmpl)
to pick up that file.
After that perform the following steps:
./Configure -Werror --strict-warnings [your-options]
make update
make
make test
`make update` ensures that your functions declarations are added to
`util/libcrypto.num` or `util/libssl.num`.
If you plan to submit the changes you made to OpenSSL
(see [CONTRIBUTING.md](CONTRIBUTING.md)), it's worth running:
make doc-nits
after running `make update` to ensure that documentation has correct format.
`make update` also generates files related to OIDs (in the `crypto/objects/`
folder) and errors.
If a merge error occurs in one of these generated files then the
generated files need to be removed and regenerated using `make update`.
To aid in this process the generated files can be committed separately
so they can be removed easily.
