I just checked the code for PHP 7.1 and in there openssl_free_key is an alias for opnessl_pkey_free (PHP_FALIAS).

This supports Richards assumption.

I would also suggest to not use the alias,
but use the openssl_pkey_free function in new code.

This is because it is more descriptive about what its intend is and is the same structure as similar function in the openssl section.

openssl_free_key and openssl_pkey_free are probably aliases.

And the preferred one is probably openssl_pkey_free.
