- 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 to pick up that file.
- After that perform the following steps:
- ./config -Werror --strict-warnings [your-options]
- make update
- 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), 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.
