• 12.6. s_server / s_client
• 12.6.1. SSL POP3 / SMTP / IMAP
• 12.6.2. server / client 文件传输

12.6. s_server / s_client

12.6.1. SSL POP3 / SMTP / IMAP

SSL POP3 / SMTP / IMAP 端口号

POP3 995
SMTP 465
IMAP 993

openssl s_client -connect localhost:110 -starttls pop3

如果提示 CONNECTED(00000003) 侧省去 -starttls pop3 选项

openssl s_client -connect pop.163.com:995

openssl s_client -connect smtp.163.com:465

openssl s_client -connect imap.163.com:993

12.6.2. server / client 文件传输

生成证书

$ openssl req -new -x509 -keyout server.pem -out server.pem -days 365 -nodes

在一个终端运行以下命令

openssl s_server -accept 2009 -key server.pem -cert server.pem

在另外一个终端运行命令如下

openssl s_client -connect localhost:2009

Example 12.1. 加密传输文件

现在我们来尝试使用使用 openssl 加密传输文件

传输 /etc/passwd 文件

$ cat /etc/passwd | openssl s_server -accept 2009 -key server.pem -cert server.pem

输出类似

$ cat /etc/passwd | openssl s_server -accept 2009 -key server.pem -cert server.pem

另一个服务器上运行

openssl s_client -connect 192.168.6.2:2009

输出类似

# openssl s_client -connect 192.168.6.2:2009
