Typedef Documentation

◆ UA_SessionHeader

typedef struct UA_SessionHeader UA_SessionHeader

Thread-local variables to force failure modes during testing.

The Session implementation differs between client and server. Still, it is expected that the Session structure begins with the SessionHeader. This is the interface that will be used by the SecureChannel. The lifecycle of Sessions is independent of the underlying SecureChannel. But every Session can be attached to only one SecureChannel.

◆ UA_Chunk

typedef struct UA_Chunk UA_Chunk

For chunked requests.

◆ UA_ProcessMessageCallback

Function Documentation

◆ SIMPLEQ_HEAD()

typedef SIMPLEQ_HEAD	(	UA_ChunkQueue	,
		UA_Chunk	)

◆ UA_SecureChannel_init()

void UA_SecureChannel_init	(	UA_SecureChannel *	channel,
		const UA_ConnectionConfig *	config )

◆ UA_SecureChannel_close()

void UA_SecureChannel_close ( UA_SecureChannel * channel )

◆ UA_SecureChannel_processHELACK()

UA_StatusCode UA_SecureChannel_processHELACK	(	UA_SecureChannel *	channel,
		const UA_TcpAcknowledgeMessage *	remoteConfig )

Process the remote configuration in the HEL/ACK handshake.

The connection config is initialized with the local settings.

◆ UA_SecureChannel_setSecurityPolicy()

UA_StatusCode UA_SecureChannel_setSecurityPolicy	(	UA_SecureChannel *	channel,
		const UA_SecurityPolicy *	securityPolicy,
		const UA_ByteString *	remoteCertificate )

◆ UA_SecureChannel_deleteBuffered()

void UA_SecureChannel_deleteBuffered ( UA_SecureChannel * channel )

Remove (partially) received unprocessed chunks.

◆ UA_SecureChannel_generateLocalNonce()

UA_StatusCode UA_SecureChannel_generateLocalNonce ( UA_SecureChannel * channel )

Wrapper function for generating a local nonce for the supplied channel.

Uses the random generator of the channels security policy to allocate and generate a nonce with the specified length.

◆ UA_SecureChannel_generateLocalKeys()

UA_StatusCode UA_SecureChannel_generateLocalKeys ( const UA_SecureChannel * channel )

◆ generateRemoteKeys()

UA_StatusCode generateRemoteKeys ( const UA_SecureChannel * channel )

◆ UA_SecureChannel_sendAsymmetricOPNMessage()

UA_StatusCode UA_SecureChannel_sendAsymmetricOPNMessage	(	UA_SecureChannel *	channel,
		UA_UInt32	requestId,
		const void *	content,
		const UA_DataType *	contentType )

◆ UA_SecureChannel_sendSymmetricMessage()

UA_StatusCode UA_SecureChannel_sendSymmetricMessage	(	UA_SecureChannel *	channel,
		UA_UInt32	requestId,
		UA_MessageType	messageType,
		void *	payload,
		const UA_DataType *	payloadType )

◆ UA_MessageContext_begin()

UA_StatusCode UA_MessageContext_begin	(	UA_MessageContext *	mc,
		UA_SecureChannel *	channel,
		UA_UInt32	requestId,
		UA_MessageType	messageType )

Start the context of a new symmetric message.

◆ UA_MessageContext_encode()

UA_StatusCode UA_MessageContext_encode	(	UA_MessageContext *	mc,
		const void *	content,
		const UA_DataType *	contentType )

Encode the content and send out full chunks.

If the return code is good, then the ChunkInfo contains encoded content that has not been sent. If the return code is bad, then the ChunkInfo has been cleaned up internally.

◆ UA_MessageContext_finish()

UA_StatusCode UA_MessageContext_finish ( UA_MessageContext * mc )

Sends a symmetric message already encoded in the context.

The context is cleaned up, also in case of errors.

◆ UA_MessageContext_abort()

void UA_MessageContext_abort ( UA_MessageContext * mc )

To be used when a failure occures when a MessageContext is open.

Note that the _encode and _finish methods will clean up internally. _abort can be run on a MessageContext that has already been cleaned up before.

◆ UA_SecureChannel_processBuffer()

UA_StatusCode UA_SecureChannel_processBuffer	(	UA_SecureChannel *	channel,
		void *	application,
		UA_ProcessMessageCallback	callback,
		const UA_ByteString *	buffer )

Process a received buffer.

The callback function is called with the message body if the message is complete. The message is removed afterwards. Returns if an irrecoverable error occured.

Note that only MSG and CLO messages are decrypted. HEL/ACK/OPN/... are forwarded verbatim to the application.

◆ UA_SecureChannel_receive()

UA_StatusCode UA_SecureChannel_receive	(	UA_SecureChannel *	channel,
		void *	application,
		UA_ProcessMessageCallback	callback,
		UA_UInt32	timeout )

Try to receive at least one complete chunk on the connection.

This blocks the current thread up to the given timeout. It will return once the first buffer has been received (and possibly processed when the message is complete).

Parameters

channel	The SecureChannel
application	The client or server application
callback	The function pointer for processing complete messages
timeout	The timeout (in milliseconds) the method will block at most.

Returns: Returns UA_STATUSCODE_GOOD or an error code. A timeout does not create an error.

◆ hideBytesAsym()

void hideBytesAsym	(	const UA_SecureChannel *	channel,
		UA_Byte **	buf_start,
		const UA_Byte **	buf_end )

Internal methods in ua_securechannel_crypto.h.

◆ decryptAndVerifyChunk()

UA_StatusCode decryptAndVerifyChunk	(	const UA_SecureChannel *	channel,
		const UA_SecurityPolicyCryptoModule *	cryptoModule,
		UA_MessageType	messageType,
		UA_ByteString *	chunk,
		size_t	offset )

Decrypt and verify via the signature.

The chunk buffer is reused to hold the decrypted data after the MessageHeader and SecurityHeader. The chunk length is reduced by the signature, padding and encryption overhead.

The offset argument points to the start of the encrypted content (beginning with the SequenceHeader).

◆ calculateAsymAlgSecurityHeaderLength()

size_t calculateAsymAlgSecurityHeaderLength ( const UA_SecureChannel * channel )

◆ prependHeadersAsym()

UA_StatusCode prependHeadersAsym	(	UA_SecureChannel *const	channel,
		UA_Byte *	header_pos,
		const UA_Byte *	buf_end,
		size_t	totalLength,
		size_t	securityHeaderLength,
		UA_UInt32	requestId,
		size_t *const	finalLength )

◆ setBufPos()

void setBufPos ( UA_MessageContext * mc )

◆ checkSymHeader()

UA_StatusCode checkSymHeader	(	UA_SecureChannel *	channel,
		const UA_UInt32	tokenId )

◆ checkAsymHeader()

UA_StatusCode checkAsymHeader	(	UA_SecureChannel *	channel,
		const UA_AsymmetricAlgorithmSecurityHeader *	asymHeader )

◆ padChunk()

void padChunk	(	UA_SecureChannel *	channel,
		const UA_SecurityPolicyCryptoModule *	cm,
		const UA_Byte *	start,
		UA_Byte **	pos )

◆ signAndEncryptAsym()

UA_StatusCode signAndEncryptAsym	(	UA_SecureChannel *	channel,
		size_t	preSignLength,
		UA_ByteString *	buf,
		size_t	securityHeaderLength,
		size_t	totalLength )

◆ signAndEncryptSym()

UA_StatusCode signAndEncryptSym	(	UA_MessageContext *	messageContext,
		size_t	preSigLength,
		size_t	totalLength )
