## pre8 File

openssl-equal-pre8.patch : TLS 1.3 cipher settings can not be changed on nginx.

openssl-equal-pre8_ciphers.patch : TLS 1.3 cipher settings can be changed on nginx. (ex. TLS13+AESGCM+AES128:TLS13+AESGCM+AES256)

The _ciphers patch file is a temporary change to the TLS 1.3 configuration.
