HOW TO CONTRIBUTE TO OpenSSL ---------------------------- Development is coordinated on the openssl-dev mailing list (see http://www.openssl.org for information on subscribing). If you would like to submit a patch, send it to rt@openssl.org with the string "[PATCH]" in the subject. Please be sure to include a textual explanation of what your patch does. You can also make GitHub pull requests. If you do this, please also send mail to rt@openssl.org with a brief description and a link to the PR so that we can more easily keep track of it. If you are unsure as to whether a feature will be useful for the general OpenSSL community please discuss it on the openssl-dev mailing list first. Someone may be already working on the same thing or there may be a good reason as to why that feature isn't implemented. Patches should be as up to date as possible, preferably relative to the current Git or the last snapshot. They should follow our coding style (see https://www.openssl.org/policies/codingstyle.html) and compile without warnings using the --strict-warnings flag. OpenSSL compiles on many varied platforms: try to ensure you only use portable features. Our preferred format for changes is "diff -u" output. One method is to use "git diff" Another is to generate it something like this: # cd openssl-work # [your changes] # ./Configure dist; make clean # cd .. # diff -ur openssl-orig openssl-work > mydiffs.patch
