tls/ssl+trojan

tls/ssl+trojan协议实现虚拟攀爬

首先安装证书工具：

yum install gnutls-utils -y   

安装完成后，可以使用如下命令查看证书工具是否安装成功：

# certtool --version

创建两个文本文件”ca.txt”和”trojan.txt”，作为证书模板来使用，文件内容分别如下：

/* ca.txt */
cn = "192.168.1.1"
organization = "GlobalSign RULTR"
serial = 1
expiration_days = 3650
ca
signing_key
cert_signing_key
crl_signing_key

/* trojan.txt */
cn = "192.168.1.1"
organization = "GlobalSign RULTR"
expiration_days = 3650
signing_key
encryption_key
tls_www_server

然后使用如下命令生成 CA 证书和 IP 地址域名证书：

# certtool --generate-privkey --outfile ca-key.pem
# certtool --generate-self-signed --load-privkey ca-key.pem --template ca.txt --outfile ca-cert.pem
# certtool --generate-privkey --outfile trojan-key.pem
# certtool --generate-certificate --load-privkey trojan-key.pem --load-ca-certificate ca-cert.pem --load-ca-privkey ca-key.pem --template trojan.txt --outfile trojan-cert.pem
