GamestatsHTTP encryption methods

Encryption methods

According to the OpenSpy Core, requests can be encrypted using one of the following algorithms:

///////////////////////////////////////////////////////////////////////////////
// GHTTPEncryptionEngine
// Summary
//		Used to select a method of encryption for HTTP requests.
typedef enum
{
	GHTTPEncryptionEngine_None,			// 0: No encryption.
	GHTTPEncryptionEngine_GameSpy,		// 1: Use standard GameSpy encryption.
	GHTTPEncryptionEngine_MatrixSsl,	// 2: Use GameSpy Chat server encryption; must
										//    #define MATRIXSSL and include matrixssl 
										//    source files.
	GHTTPEncryptionEngine_RevoEx,		// 3: Use Nintendo encryption; must #define 
										//    REVOEXSSL and include RevoEX SSL source files.
    GHTTPEncryptionEngine_Twl,          // 4: #define TWLSSL and include Twl SSL source files

	GHTTPEncryptionEngine_Default		// 5: Use GameSpy unless another engine is defined
										//    with MATRIXSSL or REVOEXSSL.
