|
|
- Client: draft 23 + 26 + 27 + 28 + final

## How To Use?
|
|
|
|
### OpenSSL Patch
|
|
|
|
```
|
|
git clone https://github.com/openssl/openssl.git
|
|
git clone https://github.com/hakasenyang/openssl-patch.git
|
|
cd openssl
|
|
patch -p1 < ../openssl-patch/openssl-equal-1.1.1_ciphers.patch
|
|
```
|
|
|
|
And then use --with-openssl in nginx or build after ./config.
|
|
|
|
### nginx HPACK Patch
|
|
|
|
Run it from the nginx directory.
|
|
|
|
If you **have a** PUSH patch, use it as follows.
|
|
|
|
``curl https://raw.githubusercontent.com/hakasenyang/openssl-patch/master/nginx_hpack_push_fix.patch | patch -p1 ``
|
|
|
|
If you **did not** patch PUSH, use it as follows.
|
|
|
|
``curl https://raw.githubusercontent.com/hakasenyang/openssl-patch/master/nginx_hpack_push.patch | patch -p1``
|
|
|
|
And then check the nginx configuration below.
|
|
|
|
### nginx Remove Server Header Patch
|
|
|
|
Run it from the nginx directory.
|
|
|
|
``curl https://raw.githubusercontent.com/hakasenyang/openssl-patch/master/remove_nginx_server_header.patch | patch -p1``
|
|
|
|
### nginx strict-sni patch
|
|
|
|
Run it from the nginx directory.
|
|
|
|
``curl https://raw.githubusercontent.com/hakasenyang/openssl-patch/master/nginx_strict-sni.patch | patch -p1``
|
|
|
|
And then run it from the openssl directory.
|
|
|
|
``curl https://raw.githubusercontent.com/hakasenyang/openssl-patch/master/openssl_ignore_log_strict-sni.patch | patch -p1``
|
|
|
|
Finally, build nginx.
|
|
|
|
Example patch is [here](https://github.com/hakasenyang/nginx-build/blob/master/strict-sni-example.patch). (nginx)
|
|
|
|
## nginx Configuration
|
|
|
|
### HPACK Patch
|
|
|
|
Add configure arguments : ``--with-http_v2_hpack_enc``
|
|
|
|
### SSL Setting
|
|
```
|
|
ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
|
|
ssl_ciphers [Copy it from below and paste it here.];
|
|
