Hello,
I have a simple rsa engine code (from engines/e_dasync.c). My code
compiles. Command "*$openssl engine -t -c*" shows the following,
openssl engine -t -c
(rdrand) Intel RDRAND engine
[RAND]
[ available ]
(dynamic) Dynamic engine loading support
[ unavailable ]
(dasync) Dummy Async engine support
[RSA]
[ available ]
I also modify *openssl.cnf* configuration as following to load this engine,
openssl_conf = openssl_def
[openssl_def]
engines = engine_section
[engine_section]
rsa-engine-new = rsa_section
[rsa_section]
engine_id = rsa-engine-new
Then when I run the command "$*openssl engine*", I get the following error,
$openssl engine
(rdrand) Intel RDRAND engine
(dynamic) Dynamic engine loading support
(dasync) Dummy Async engine support
139633213376256:error:260AB089:engine

Any help why is this happening? How can I fix this?
My goal is to use my OpenSSL engine with Apache for mod_ssl. Do I have to
compile my engine with the OpenSSL source code to do that?
Here is the complete source code of my sample engine,
