[EXTERNAL] Re: ENGINE API replacement for Openssl3.0

[Shivakumar Poojari]

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

Hello,

there is no direct replacement. The ENGINEs as a pluggable crypto
modules concept is replaced with the providers concept which is much
more sophisticated and capable.

Please look at
https://clicktime.symantec.com/3NTnN1ZFia2bCryEiZnkRmY6H2?u=https%3A%2F%2Fwww.openssl.org%2Fdocs%2Fman3.0%2Fman7%2Fmigration_guide.html

ENGINEs support is not removed from OpenSSL 3.0 however it is
deprecated. If you cannot use deprecated functions you have to drop
support for engines which means those functions just should not be
called and there is no replacement.

Providers allow for configuration via the default configuration file so
for an application to support crypto modules in form of providers the
application does not necessarily have to have any extra functions
called. Just the default configuration file has to be present and the
configuration of the desired provider(s) needs to be there.

Tomas
