+Subject: [PATCH 1/2] OpenSSL: Fix private key password handling with OpenSSL
+ >= 1.1.0f
+
+Since OpenSSL version 1.1.0f, SSL_use_PrivateKey_file() uses the
+callback from the SSL object instead of the one from the CTX, so let's
+set the callback on both SSL and CTX. Note that
+SSL_set_default_passwd_cb*() is available only in 1.1.0.

+Subject: [PATCH 2/2] OpenSSL: Clear default_passwd_cb more thoroughly
+
+Previously, the pointer to strdup passwd was left in OpenSSL library
+default_passwd_cb_userdata and even the default_passwd_cb was left set
+on an error path. To avoid unexpected behavior if something were to
+manage to use there pointers, clear them explicitly once done with
+loading of the private key.
