Patch files

You can find the OpenSSL 1.1.0h patch is here.

Here is the basic patch content.

• Support TLS 1.3 draft 23 + 26 + 28 (Not support pre2)
  • Server: draft 23 + 26 + 28
  • Client: draft 23 + 26 + 27 + 28
• BoringSSL's Equal Preference Patch
• Weak 3DES and not using ECDHE ciphers is not used in TLSv1.1 or later.

Patch file name	Patch list
openssl-equal-pre2.patch	Not support draft 26, 28.
openssl-equal-pre7.patch openssl-equal-pre8.patch openssl-equal-pre9.patch	TLS 1.3 cipher settings can not be changed on nginx.
openssl-equal-pre7_ciphers.patch openssl-equal-pre8_ciphers.patch openssl-equal-pre9_ciphers.patch	TLS 1.3 cipher settings can be changed on nginx.

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

Example of setting TLS 1.3 cipher in nginx (pre7 or higher):

Example	Ciphers
Short Cipher	TLS13+AESGCM+AES128:TLS13+AESGCM+AES256:TLS13+CHACHA20
Fullname Cipher	TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256
TLS 1.3 + 1.2 ciphers	TLS13+AESGCM+AES128:EECDH+AES128

Not OpenSSL patch files

Patch file name	Patch list
nginx_hpack_push.patch	Patch both the HPACK patch and the PUSH ERROR.
nginx_hpack_push_fix.patch	Patch only the PUSH ERROR of the hpack patch. (If the HPACK patch has already been completed)
remove_nginx_server_header.patch	Remove nginx server header. (http2, http1.1)

nginx Configuration
