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 From: Tomas Mraz <tomas@xxxxxxxxxxx>

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.
