用Java检测HTTPS网站所支持的TLS版本信息

用Java检测HTTPS网站所支持的TLS版本信息

简介

服务器升级、JDK升级、API升级等都可能会造成原有HTTPS的API调不通的情况。造成这种情况的原因有许多,但千万别忽视TLS和证书的问题。

有许多工具和软件可以做检测,下面来介绍常用的几种。

检测工具介绍

curl

当用curl去连接时,可以打印对应的Protocal和cipher信息:

$ curl -k -v https://www.pkslow.com
*   Trying 119.23.215.59:443...
* Connected to www.pkslow.com (119.23.215.59) port 443
* ALPN: curl offers h2,http/1.1
* (304) (OUT), TLS handshake, Client hello (1):
* (304) (IN), TLS handshake, Server hello (2):
* TLSv1.2 (IN), TLS handshake, Certificate (11):
* TLSv1.2 (IN), TLS handshake, Server key exchange (12):
* TLSv1.2 (IN), TLS handshake, Server finished (14):
* TLSv1.2 (OUT), TLS handshake, Client key exchange (16):
* TLSv1.2 (OUT), TLS change cipher, Change cipher spec (1):
* TLSv1.2 (OUT), TLS handshake, Finished (20):
* TLSv1.2 (IN), TLS change cipher, Change cipher spec (1):
* TLSv1.2 (IN), TLS handshake, Finished (20):
* SSL connection using TLSv1.2 / ECDHE-RSA-AES128-GCM-SHA256
* ALPN: server accepted http/1.1
* Server certificate:
*  subject: CN=pkslow.com
*  start date: Feb  1 11:09:56 2024 GMT
*  expire date: May  1 11:09:55 2024 GMT
*  issuer: C=US; O=Let's Encrypt; CN=R3
*  SSL certificate verify ok.
* using HTTP/1.1
> GET / HTTP/1.1
> Host: www.pkslow.com
> User-Agent: curl/8.4.0
> Accept: */*
> 
< HTTP/1.1 200 OK
< Server: nginx/1.14.1
< Date: Fri, 15 Mar 2024 07:45:35 GMT
< Content-Type: text/html
< Content-Length: 94562
< Connection: keep-alive
< Content-Language: en-US

还可以设定最大的TLS版本:

curl -k -v --tls-max 1.2 https://www.pkslow.com

kali sslscan

Kali提供了 sslscan ,在Mac安装如下:

brew install sslscan

测试:

$ sslscan www.pkslow.com:443
Version: 2.0.6-static
OpenSSL 1.1.1g  21 Apr 2020

Connected to 119.23.215.59
