void* ksnEncryptPackage	(	ksnCryptClass *	kcr,
		void *	package,
		size_t	package_len,
		void *	buffer,
		size_t *	encrypt_len
	)

Encrypt KSNet package.

Parameters

	kcr	Pointer to ksnetCryptClass object
	package	Package to send
	package_len	Package length
	buffer	Buffer to encrypt, enough to hold encrypted data (package_len + 16)
[out]	encrypt_len	Length of encrypted data

Returns

If buffer = NULL this function return allocated pointer to encrypted buffer with data. Should be free after use. Other way it return pointer to input buffer.
