make error while following the procedure in apache2.md #14

Hey, I was trying to enable eSNI on my Apache server and am following the steps as given in https://github.com/sftcd/openssl/blob/master/esnistuff/apache2.md

After "./configure --enable-ssl --with-ssl=$HOME/code/openssl-for-apache --with-libxml2" when i try make, it gives the following error:

Is this a mistake on my end or the code itself? And how can I try and fix this?

Thank you

It's worth noting that ESNI has evolved into ECH over the last year, and so e.g. I don't think firefox nightly now includes support for ESNI, but will hopefully add ECH soonish. (There is NSS code for ECH but afaik not yet integrated with ff.)

As a bit of background: ESNI just encrypted the SNI in a TLS handshake extension, whereas ECH (Encrypted ClientHello) allows for encryption of an entire "inner" ClientHello within an "outer" ClientHello, and seems overall a better (if more complex) design.

All that being to say that if you're doing this in an expectation that ESNI will be part of e.g. browsers in the future, that might not be a great plan. ECH however isn't yet present in browsers as we're just at the point of ironing out the last interoperability issues. But the hope is that ECH will become part of browsers and web servers going forward.

After "./configure --enable-ssl --with-ssl=$HOME/code/openssl-for-apache --with-libxml2" when i try make, it gives the following error:


......warnings.......

ssl_engine_init.c:334:17: error: too few arguments to function ‘SSL_CTX_esni_server_enable’
              if (SSL_CTX_esni_server_enable(ctx,privname,pubname)!=1) {

If (given the above) you still want to try this out, I can take a look at that as I'm nearly back at the point of doing application integrations for ECH again.

All the deprecations below are basically changes to upstream over the last year. I've not yet bothered to fix them as the ESNI code in my fork is likely to disappear once ECH is a bit more developed. For now, I've left it in just in case;-)

So if you're happy to wait a month(-ish) more and then try out ECH, that'd maybe be a more useful thing for you longer term. If you have a pressing need for trying out ESNI, I'd be happy to look at the error above but it probably doesn't make sense to try fix the deprecation warnings.

Cheers, S.

Is this a mistake on my end or the code itself? And how can I try and fix this?

Thank you

Hey, I looked into ECH over the past few days and understand that it will be the standard going into the future. The project I am working on currently involves the decryption of the ESNI field, I believe the method will carry over to ECH (just a bit more complex) since SNI along with other fields will be encrypted there.

My current goal is to work with the decrypted ESNI value, and hence I would be extremely grateful if you could look into the error whenever possible Thank you

ESNI stuff is legacy nowadays: closing
