How to load a custom OpenSSL engine automatically?

[Shariful Alam <dipto181@xxxxxxxxx>]

Hello,

I have a custom OpenSSL engine for experiment purposes. I'm trying to load my engine automatically. I intend to use my custom engine instead of the default OpenSSL engine. I have installed OpenSSL 1.1.1c from the source code with, 

./config --prefix=/opt/openssl -DOPENSSL_LOAD_CONF --openssldir=/opt/openssl/ssl  

configuration. And add the following lines to my openssl.cnf,

openssl_conf = openssl_def

[openssl_def]
engines = engine_section

[engine_section]
rsa-engine-new = rsa_section

[rsa_section]
engine_id = rsa-engine-new
#dynamic_path = /opt/openssl/lib/engines-1.1/rsa-engine-new.so  <-- Uncomment this line cause segmentation fault

after this, when I try to list available engine, I get the following error,

ss@ss:/usr/local/lib$ openssl engine

rsa-engine-new

(rdrand) Intel RDRAND engine

(dynamic) Dynamic engine loading support

(rsa-engine-new) engine for testing 1

140659701942016:error:260AB089:engine routines:ENGINE_ctrl_cmd_string:invalid cmd name:crypto/engine/eng_ctrl.c:255:

My engine is loading automatically and it is used as a default engine, but why I'm seeing those errors? And how can I fix it?

Sincerely,

Shariful Alam
