SSL Proxy

Extend existing clients and servers with secure data transport!

What is SSL Proxy?

You probably know secure HTTP from secure web sites. Say, you want to operate a secure web server but have only a normal server. SSL Proxy can be your solution: It's plugged into the connection between the client and the server and adds Secure Socket Layer (SSL) support. Or the other way around: You have an ordinary telnet client but want to connect to a secure site. Just start SSL Proxy with the appropriate parameters and -- voila. That's what SSL Proxy can do for you.


Please access the original README document (also included in download packages).

On what platforms does SSL Proxy run?

Is SSL Proxy legal?

The answer to this question depends on a lot of factors. It is as legal as SSLeay is, because it builds on top of this library. For a detailed discussion of the legal problems please read the SSLeay FAQ at
