Apache module development

I'm currently looking for a developer who can build a production ready version of our concept plugin. One that is backwards compatible with older versions of Apache and can share share the majority of code with the Nginx plugin later. The concept plugin does not contain all final functionality, for example threading is not handled for some processes where it should and message authentication needs to be implemented via digital signatures.

The concept plugin only works on the current Apache trunk (2.5) because it's using the 'init_server' hook which was just recently added. This is the biggest challenge to resolve. The module mod_sslhaf could potentially help you in the right direction as this is already extracting the required information in the TLS handshake.

Apache Function:

[url removed, login to view]

mod_sslhaf (Apache module for passive SSL client fingerprinting):

[url removed, login to view]

The developer needs to find a way to make a similar 'hook' in older versions of Apache 2.x but with the existing functionality and without (re)writing mod_ssl. We can't make any changes to the Apache source, everything needs to happen in this module so that it can be installed with a simple 'apt-get install', 'yum install'.

In the 'init_server' hook we use the OpenSSL hook 'SSL_CTX_set_tlsext_servername_callback', which makes the module compatible with OpenSSL version [url removed, login to view] and higher.

We can share the concept plugin to developers who have a good idea to solve the problem, set your budget on the module based implementation of this change. We can agree on the final budget later.

I can only accept your bid if you can explain how you would like to implement the back-port. Project fee will only be paid for a successful and secure implementation as described above.

Hi, I carefully read your project description, here is what I understand. In the Apache 2.5 you use SSL_CTX_set_tlsext_servername_callback I guess to retrieve the TLS server name, if it’s the case we can have the s Más
