Classes
struct	MAVLinkSigning::DetectSnapshot
	Single-lock snapshot struct; fields populated by SigningChannel::detectSnapshot(). More...

Namespaces
namespace	MAVLinkSigning

Typedefs
typedef struct __mavlink_setup_signing_t	mavlink_setup_signing_t
using	MAVLinkSigning::SigningKey = std::array< uint8_t, kSigningKeySize >
	std::array avoids QByteArray COW detach so secureZero() actually wipes the bytes.

Enumerations
enum class	MAVLinkSigning::UnsignedAcceptancePolicy : uint8_t { MAVLinkSigning::Strict , MAVLinkSigning::Pending }

Functions
const QDateTime &	MAVLinkSigning::signingEpoch ()
	MAVLink wire-protocol epoch; must be UTC per spec.
uint64_t	MAVLinkSigning::currentSigningTimestampTicks ()
	Current signing timestamp in 10µs ticks since 2015-01-01.
std::optional< SigningKey >	MAVLinkSigning::makeSigningKey (QByteArrayView bytes)
	Build a SigningKey from arbitrary bytes. Returns nullopt if input is the wrong size.
bool	MAVLinkSigning::secureConnectionAcceptUnsignedCallback (const mavlink_status_t *status, uint32_t message_id)
bool	MAVLinkSigning::insecureConnectionAcceptUnsignedCallback (const mavlink_status_t *status, uint32_t message_id)
mavlink_accept_unsigned_t	MAVLinkSigning::callbackForPolicy (UnsignedAcceptancePolicy policy)
	Maps a high-level policy to the underlying libmavlink callback.
void	MAVLinkSigning::createSetupSigning (mavlink_channel_t channel, mavlink_system_t target_system, QByteArrayView keyBytes, mavlink_setup_signing_t &setup_signing)
	Build a SETUP_SIGNING payload. Empty keyBytes produces a disable payload (zero key, zero timestamp).
bool	MAVLinkSigning::encodeSetupSigning (mavlink_channel_t channel, uint8_t srcSysId, uint8_t srcCompId, mavlink_system_t target_system, QByteArrayView keyBytes, mavlink_message_t &message)
bool	MAVLinkSigning::isMessageSigned (const mavlink_message_t &message)
	Returns true if the message has a MAVLink2 signature.
void	MAVLinkSigning::setMessageSigned (mavlink_message_t &message, bool isSigned)
	Set or clear the MAVLink2 signature incompatibility flag on a message.
QByteArray	MAVLinkSigning::serializeUnsignedCopy (const mavlink_message_t &message)
bool	MAVLinkSigning::verifySignature (QByteArrayView key, const mavlink_message_t &message)
	Verify a key against a signed message's signature.
bool	MAVLinkSigning::verifySignature (const SigningKey &key, const mavlink_message_t &message)
void	MAVLinkSigning::logSigningFailure (mavlink_channel_t channel)
bool	MAVLinkSigning::checkSigningLinkId (mavlink_channel_t channel, const mavlink_message_t &message)
QString	MAVLinkSigning::signingStatusString (mavlink_channel_t channel)
int	MAVLinkSigning::signingStreamCount (mavlink_channel_t channel)
