+
+OpenSSL 1.1 compatibility.
+
+Allocate contexts from the heap on all OpenSSL versions, this is needed
+since OpenSSL 1.1.0. No attempt is done at addressing issues like global
+variables and fixing potential memleaks on error paths.
+
+Compile-tested only with OpenSSL 1.1.0e (Arch Linux) and OpenSSL 1.0.2g
+(Ubuntu 16.04), I have no test file.
+
+Fixes https://github.com/Lekensteyn/dmg2img/issues/4
