Can you point to instructions on how to load provider

Is there something similar to "[engine_section]",
that can be used to configure loading from openssl.conf?
Yes. See the "config" man page here:
https://www.openssl.org/docs/man3.0/man5/config.html
And here are some simple config files that do this:
https://github.com/openssl/openssl/blob/master/test/default.cnf
https://github.com/openssl/openssl/blob/master/test/default-and-fips.cnf
https://github.com/openssl/openssl/blob/master/test/default-and-legacy.cnf
https://github.com/openssl/openssl/blob/master/test/fips-and-base.cnf
https://github.com/openssl/openssl/blob/master/test/fips.cnf

In particular look at the section "Provider Configuration"
You can also load providers through the API. See:
https://www.openssl.org/docs/man3.0/man3/OSSL_PROVIDER_load.html

Another, slightly more complicated, but fully self contained provider is
here:
https://github.com/openssl/openssl/blob/master/test/tls-provider.c
And another one here:
https://github.com/openssl/openssl/blob/master/test/p_test.c
A minimal bare bones provider is here:
https://github.com/openssl/openssl/blob/master/providers/nullprov.c
The legacy provider is also worth looking at:
https://github.com/openssl/openssl/blob/master/providers/legacyprov.c

Shiva,
you may also have a look at
thehttps://github.com/provider-corner/vigenere
That's (as far as I know) the most simple provider implementation
available.

Subject: Re: [EXTERNAL] Re: ENGINE API replacement for Openssl3.0
I am sorry but as I said providers are not a direct replacement for
ENGINEs. It is a completely different implementation of the same
concept of pluggable cryptographical modules for OpenSSL. You can
look at the OpenSSL manual pages for the providers.
This is the starting point:
https://www.openssl.org/docs/man3.0/man7/provider.html
There is no tutorial as for how to implement your own provider. And
as I said on the application side if the application loads an
OpenSSL configuration file the providers loaded can be configured
via the config file and does not require any explicit API calls from
the application.
I'd recommend looking at some of the test sources in the tests
directory for some code examples.

Hi Tomas,
As Engine function are deprecated I tried using providers
But how to use providers to get engine functionality tried in man
pages
Some sample program will help, maybe some sample program will give the
clear idea how to use provider
Struggling in understand the providers
Please share the sample program and the links to understand the
providers
Thanks,
shiva kumar
