还在用Windows 2003服务器的朋友注意啦

如果你仍有旧的应用在Windows 2003上，对于SSL这已经是一个淘汰的操作系统了。它不支持TLS 1.1和1.2，更不要说TLS 1.3了，在SSL成为网站标配的今天，请务必升级操作系统。

SSL Protocol: These are the following list of protocols which have been released till date:

1. SSL 1.0, 2.0 and 3.0
2. TLS 1.0 (or SSL 3.1, released in 1999)
3. TLS 1.1 (or SSL 3.2, released in 2006)
4. TLS 1.2 (or SSL 3.3, released in 2008) NOTE: Windows Server 2008 R2 and Windows 7 are the only 2 OS which support TLS 1.1 and TLS 1.2 in 2008. All the OS’s before this don’t support these 2 protocols.
