From fcb77b6b49ad76dea8c856e3a3a8cbc7f614d1d2 Mon Sep 17 00:00:00 2001 From: tb Date: Tue, 23 May 2023 11:51:12 +0000 Subject: [PATCH] Simplify OBJ_obj2txt() Instead of adding a NUL termination to OBJ_obj2txt(), move the aobj == NULL or aobj->data == NULL checks to i2t_ASN1_OBJECT_internal(). The only other caller, i2t_ASN1_OBJECT(), fails on aobj == NULL and aobj->length == 0, and the latter condition is implied by aobj->data.
