Re: Question about adding new cipher to openssl and then testing through apache httpd

I'm not sure you need to do anything in OpenSSL.

When I build Apache against LibreSSL, I have access to ciphers in LibreSSL that are (or were) not in OpenSSL.

As long as your new cipher doesn't trigger any blacklists in the mod_ssl source it should be picked up and available as long as a client supports it too.

Hello,

I have created a custom version of Openssl v1.1 where I am testing a new
cipher algorithm. I now wish to integrate and test in Apache HTTP. Where
in the source code do I need update in order to get Apache HTTP to
recognize the new cipher? I can list the new cipher using the "openssl
ciphers" command:

/usr/local/ssl/bin/openssl ciphers

ECDHE-ECDSA-CIPHERTEST256-SHA256:ECDHE-RSA-CIPHERTEST256-SHA256:ECDHE-ECDSA-CIPHERTEST128-SHA256:ECDHE-RSA-CIPHERTEST128-SHA256:CIPHERTEST256-SHA256:CIPHERTEST128-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-DSS-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-CCM8:..

I initially tried compiling 2.4 with the custom OpenSSL and then listing
the new ciphers in the
SSLCipherSuite directive but they were not recognized.

NOTES:
Server version: Apache/2.4.24-dev (Unix)
Server built:   Jan  8 2017 00:11:07

OpenSSL 1.1.1-TEST-dev  xx XXX xxxx

Thanks in advance!
