◆ GWEN_CryptMgr_Decode()

GWENHYWFAR_API int GWEN_CryptMgr_Decode	(	GWEN_CRYPTMGR *	cm,
		const uint8_t *	pData,
		uint32_t	lData,
		GWEN_BUFFER *	dbuf
	)

Decrypt the given data which is expected to be an encrypted object containing a signed object which actually contains the data. The signature of the contained signed object is verified.
