From 89f5af84affc07f01d2bae3797a2bd97dd3786b7 Mon Sep 17 00:00:00 2001 From: Valerio Setti Date: Thu, 18 Apr 2024 06:54:32 +0200 Subject: adjust_legacy_crypto: enable ASN1_[PARSE|WRITE]_C when RSA_C RSA needs ASN1 functions to parse/write private and public keys, but there is no guards in the code for that. So we need to enable ASN1 support whenever RSA is enabled.
