+Adding OpenSSL Support
+=====
+
+Civetweb supports *HTTPS* connections using the OpenSSL transport layer 
+security (TLS) library. OpenSSL is a free, open source library (see
+http://www.openssl.org/).
+
+
+Getting Started
+----
+
+- Install OpenSSL on your system. There are OpenSSL install packages for all
+  major Linux distributions as well as a setup for Windows.
+- The default build configuration of the civetweb web server will load the
+  required OpenSSL libraries, if a HTTPS certificate has been configured.
+  
+
+Civetweb Configuration
+----
+  
+The configuration file should contain an https port, e.g.
+  listening_ports 80, 443s
+to server http and https from their standard ports, or  
+  listening_ports 443s
+to serve only https.
+
+Furthermore the SSL certificate file must be set, e.g.
+  ssl_certificate d:\civetweb\certificate\server.pem
+
+  
+Creating a self signed certificate
+----
+
+OpenSSL provides a command line interface, that can be used to create the 
+certificate file required by civetweb (server.pem). 
+
+One can use the following steps in Windows (in Linux replace "copy" by "cp"
+and "type" by "cat"):
+
+  openssl genrsa -des3 -out server.key 1024
+  
+  openssl req -new -key server.key -out server.csr
+  
+  copy server.key server.key.orig
+  
+  openssl rsa -in server.key.orig -out server.key
+  
+  openssl x509 -req -days 3650 -in server.csr -signkey server.key -out server.crt
+  
+  copy server.crt server.pem
+  
+  type server.key >> server.pem
+
+
+The server.pem should look like this (x represents BASE64 encoded data):
+
