将SS的加密算法改为chacha20

#gfw#shadowsocks92
AI-generated summary
This article discusses how to change the encryption algorithm of Shadowsocks to chacha20, which can improve the speed of key encryption and decryption and avoid packet tracking issues. It provides instructions on installing the necessary tools and libraries, updating the configuration file, and restarting the server.

Shadowsocks 更换加密算法后可以提高密钥加密和解密速度，同时可以规避 GFW 利用 OpenSSL 特性进行特征包跟踪的问题。

环境确认，安装编译工具

# Debian/Ubuntu
apt-get install build-essential

CentOS#

yum groupinstall "Development Tools"

下载、编译和安装 libsodium1.0.11，支持 chacha20

# 下载 libsodium

wget https://github.com/jedisct1/libsodium/releases/download/1.0.11/libsodium-1.0.11.tar.gz
tar xvf libsodium-1.0.11.tar.gz

编译 & 安装#

cd libsodium-1.0.11
./configure && make && make install

更新动态库#

ldconfig

编辑服务器配置文件

vim /etc/shadowsocks/config.json

config.json 文件配置

{
"server":"0.0.0.0",
"server_port":443,
"password":"password",
"method":"chacha20", //chacha20 加密算法
"timeout":120,
"fast-open",
"workers":1
}

重启服务器，此时服务器配置完成
