From 2cb802e16fff3fb2c57ae664baa7bd9ce3e33805 Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Sun, 7 Nov 2021 06:18:16 +0100 Subject: Fix DER encoder implementations for output structures "EC" and "SM2" These DER encoder implementations are supposed to be aliases for the "type-specific" output structure, but were made different in so far that they would output a "type specific" public key, which turns out to be garbage (it called i2o_ECPublicKey()). The "type-specific" output structure doesn't support that, and shouldn't.
