+Subject: [PATCH] Port to OpenSSL 1.1.0
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+OpenSSL 1.1.0 hid ECDSA structure internals and provided methods
+instead.
+
+This patch uses the methods and provides their copies in the case of
+older OpenSSL. Because the new OpenSSL API, ECDSA_SIG_set0(), cannot
+set curve parameters individually and ECDSA_SIG_get0() returns yet
+another reference, it's necessary to duplicate the other unchanged
+paramater when calling set_r() or set_s().
+
+This patch also stops exporting ECDSA_METHOD functions that were
+removed from the new OpenSSL.
+
+CPAN RT#118330
