Last October, I wrote “CHACHA20 Apache official version already supports but Apache Lounge version 2.4.23, which is my server current version, hasn’t yet“. On April 19, Steffen announced Apache 2.4.26-Dev available with Openssl 1.1.0e VC14. So, we can use CHACHA20_POLY1305 in the Windows version Apache now. For enabling the cipher you need to add CHACHA20-POLY1305 things to the SSLCipherSuite of the httpd-ssl.conf and reboot the Apache.
