Hi, At the moment the minimal OpenSSL version is 0.9.6.
I realised yesterday that there are some types changes between 0.9.7 and 0.9.8 that would have to be address in overflow checks (EVP_DigestUpdate and related). I also noticed that 0.9.6 might not even compile without warnings as it's checking return type for some function that did not return anything in 0.9.6. We also have few other old places where we don't check retval because of that. The thing is that the last update for 0.9.7 stable branch is in 2008 and 0.9.6 in 2005. Both of them have been long time EOL so I don't think that it makes any sense to spend any time on making them compatible for PHP 7. So I think we should bump minimal version to 0.9.8. Anatol would you be ok if this is done for 7.0? I don't think that anyone would ever use PHP 7 and such an old version of OpenSSL together so there should be no issue IMHO. Cheers Jakub
