-15.1 Other authentication mechanisms
+15.1 Add support for client certificate authentication
+
+ WinSSL/SChannel currently makes use of the OS-level system and user
+ certificate and private key stores. This does not allow the application
+ or the user to supply a custom client certificate using curl or libcurl.
+
+ Therefore support for the existing -E/--cert and --key options should be
+ implemented by supplying a custom certificate to the SChannel APIs, see:
+ - Getting a Certificate for Schannel
+   http://msdn.microsoft.com/en-us/library/windows/desktop/aa375447.aspx
+
+15.2 Add support for custom server certificate validation
+
+ WinSSL/SChannel currently makes use of the OS-level system and user
+ certificate trust store. This does not allow the application or user to
+ customize the server certificate validation process using curl or libcurl.
+
+ Therefore support for the existing --cacert or --capath options should be
+ implemented by supplying a custom certificate to the SChannel APIs, see:
+ - Getting a Certificate for Schannel

+
+15.3 Add support for the --ciphers option
+
+ The cipher suites used by WinSSL/SChannel are configured on an OS-level
+ instead of an application-level. This does not allow the application or
+ the user to customize the configured cipher suites using curl or libcurl.
+
+ Therefore support for the existing --ciphers option should be implemented
+ by mapping the OpenSSL/GnuTLS cipher suites to the SChannel APIs, see
