##ss加密算法 常用算法aes-256-cfb速度较慢，在路由器等arm平台表现不佳。 用于arm平台时，采用算法rc4-md5即可。 "method":"rc4-md5" 为加速加密速度，安装m2crypto

yum install m2crypto

# 生成 dhparam.pem 文件, 在命令行执行任一方法:

# 方法1: 很慢
openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048

# 方法2: 较快
# 与方法1无明显区别. 2048位也足够用, 4096更强
openssl dhparam -dsaparam -out /etc/nginx/ssl/dhparam.pem 4096

# to generate your dhparam.pem file, run in the terminal
openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048
