## Patch files
|
|
|
|
### The equal preference patch(openssl-equal-x) already includes the tls13_draft patch and the tls13_nginx_config(_ciphers file only) patch. Therefore, you do not need to patch it together.
|
|
|
|
You can find the _OpenSSL 1.1.0h_ patch is [here.](https://gitlab.com/buik/openssl/blob/openssl-patch/openssl-1.1/OpenSSL1.1h-equal-preference-cipher-groups.patch)
|
|
|
|
Here is the basic patch content.
|
|
- BoringSSL's Equal Preference Patch
|
|
- Weak 3DES and not using ECDHE ciphers is not used in TLSv1.1 or later.

## 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-3.0.0-dev_ciphers.patch
|
|
```
|
|
|
|
And then use --with-openssl in nginx or build after ./config.
|
|
|
|
### OpenSSL CHACHA20-POLY1305-OLD Patch
|
|
|
|
Thanks [@JemmyLoveJenny](https://github.com/JemmyLoveJenny)!
|
|
|
|
[View issue](https://github.com/hakasenyang/openssl-patch/issues/1#issuecomment-427554824) / [Original Source](https://github.com/JemmyLoveJenny/ngx_ossl_patches/blob/master/ossl_enable_chacha20-poly1305-draft.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-1.1.1a-chacha_draft.patch
|
|
```
|
|
|
|
### 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``
|
|
|
|
This is a condition for using strict sni. [View issue.](https://github.com/hakasenyang/openssl-patch/issues/7#issuecomment-427664716)
|
|
|
|
- How to use nginx strict-sni?
|
|
- **ONLY USE IN http { }**
|
|
- strict_sni : nginx strict-sni ON/OFF toggle option.
|
|
- strict_sni_header : if you do not want to respond to invalid headers. (**only with strict_sni**)
|
|
- Strict SNI requires at least two ssl server (fake) settings (server { listen 443 ssl }).
|
|
- It does not matter what kind of certificate or duplicate.
|
|
- (>1.15.10) If no SNI is required, print the certificate without applying strict-SNI.
|
|
|
|

|
|
|
|
### nginx OpenSSL-1.1.x Renegotiation Bugfix
|
|
|
|
It has already been patched by nginx >= 1.15.4.
|
|
|
|
Run it from the nginx directory.
|
|
|
|
``curl https://raw.githubusercontent.com/hakasenyang/openssl-patch/master/nginx_openssl-1.1.x_renegotiation_bugfix.patch | patch -p1``
|
|
|
|
## 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.];
|
|
ssl_ecdh_curve X25519:P-256:P-384;
|
|
ssl_prefer_server_ciphers on;
|
|
```
|
|
|
|
### OpenSSL-1.1.1a, 3.0.0-dev ciphers

|
|
```
|
|
|
|
## Other.
|
|
|
|
### nginx ocsp shell
|
|
|
|
The configuration file recognizes the ***.conf** file in **/etc/nginx**.
|
|
|
|
Precedence settings in **nginx.conf** are as follows:
|
|
|
|
worker_processes 1 - **If this number is high, the remaining worker processes do not have OCSP Stapling values.**
|
|
|
|
After reload or restart, execute the corresponding shell. That's it!
|
|
|
|
I tried to edit nginx, but I have not found a good way yet. :(
