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://www.openssl.org/docs/man3.0/man7/migration_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.
