I'm assisting with the port of the python package M2Crypto to use OpenSSL 1.1.0. The latest windows build of python 2.7.12 still does not include applink.c, which leaves us unable to use BIO_s_fd functions and those BIO_s_file functions that accept FILE objects.
I'd like to offer patch #1356 (https://github.com/openssl/openssl/pull/1356) The patch modifies how OPENSSL_Uplink() searches for the applinktable. Instead of only searching within the process space of the application, it enables a developer to register an optional applinktable stored in another module (aka another DLL). The solution requires the developer to ensure the call to OPENSSL_SetApplink() is made from an extension that was compiled using the same threading model as both python and the installed OpenSSL library. But, because python's distutils system is fully aware of the build environment, this is a trivial matter for python developers. The patch includes documentation along with detailed example of how to use it. begin 666 smime.p7s M,( &"2J&2(;W#0$'`J" ,( "`0$Q"S )!@4K#@,"&@4`,( &"2J&2(;W#0$' M`0``H((.$3""!#8P@@,>H ,"`0("`0$P#08)*H9(AO<-`0$%!0`P;S$+, D& M`U4$!A,"4T4Q%# 2!@-5!
