openssl 1.1 compatibility ?

[kapouer]

Hi,

debian will ship nginx with openssl 1.1 support, meaning... one won't be able to
run this module in next's debian stable. Any plans about that ?

I was trying to get this library to work on the kubernetes nginx ingress controller and ran into the issue of it not working with openssl 1.1.0. Getting the error failed to find function/global EVP_MD_CTX_create.

I tried some simple stuff, and it seems to simply be fixed by editing evp.lua and changing all instances of the following two strings:

Change This	To This
EVP_MD_CTX_create	EVP_MD_CTX_new
EVP_MD_CTX_destroy	EVP_MD_CTX_free

Those two changes seem to make it work.
