Re: Using Apache 2.0 with mod_ssl and custom engine on openssl

Thank you Daniel for your help.

I believe a bad part (or an important feature that does not exist) of mod_ssl is the lack of ability to pass any argument or parameter to the crypto device that you want to use. Do you know anything about passing a parameter (command in openssl engine terminology)? Otherwise, I may need to hardcode the parameters into the custom openssl engine, which isn't very nice though.

Hi,

My question may seem rather complex, but I believe someone can answer it.

1 - I've implemented a custom OpenSsl Engine, which works perfectly
fine in OpenSsl.
2 - I want to create a sample web site that uses https with Apache.
After my search, I saw that Apache uses mod_ssl to support https.
Mod_ssl is based on openssl.

That's where my question comes in:

When mod_ssl uses openssl in the backend, I want it to use my custom
Openssl Engine implementation. Is it possible?

I hope that i'm clear.

Thanks,

Erman

Hi, Erman;
    Yes, you can in 2.0. In order to use an engine, though, you must
compile httpd with -DSSL_EXPERIMENTAL_ENGINE. This will enable the
SSLCryptoDevice directive which will be set to the name of your engine.
This compile flag was dropped in 2.2 which made SSLCryptoDevice part of
a 'normal' build.
