+/*******************************************************************************
+
+    Starting from OpenSSL v1.1.0, the `sk_*` functions are prefixed with
+    `OPENSSL_`, so e.g. `sk_num` becomes `OPENSSL_sk_num`.
+
+    To cope with that and provide downstream with an easier interface to deal
+    with, we always provide the `OPENSSL_` methods, as they are just `extern(C)`
+    anyway, and we either provide `sk_*` as `alias`es or `extern (C)`.
+
+    The need for aliases comes from users of those binding, e.g. `safestack`.
