Detailed Description

Encapsulates DS resource record data.

See RFC 4034 for details.

Constructor & Destructor Documentation

◆ RRDataDS()

Dwm::Dns::RRDataDS::RRDataDS	(	uint16_t	keyTag,
		uint8_t	algorithm,
		uint8_t	digestType,
		const std::string &	digest
	)

Constructs DS resource record dats with keyTag, algorithm, digestType and digest.

Member Function Documentation

◆ Decode()

const uint8_t* Dwm::Dns::RRDataDS::Decode	(	const uint8_t *	pkt,
		const uint8_t *	ptr,
		uint16_t	pktlen,
		uint16_t	rdlen
	)

virtual

Decodes the DS resource record data from buffer pkt of length pktlen, starting at ptr.

Returns the address immediately following the encoded DS resource record data in pkt on success. Throws std::out_of_range if pkt was too short to contain an encoded DS resource record data.

Implements Dwm::Dns::RRData.

◆ Encode()

uint8_t* Dwm::Dns::RRDataDS::Encode	(	uint8_t *	pkt,
		uint8_t *	ptr,
		uint16_t	pktlen,
		LabelPositions &	lps
	)		const

virtual

Encodes the DS resource record data into buffer @ pkt of length pktlen, starting at ptr.

Returns the address immediately following the encoded DS resource record data in pkt on success. Throws std::out_of_range if pkt is too short to contain the encoded DS resource record data.

Implements Dwm::Dns::RRData.
