void ProtocolPP::jdtls13::decap_packet	(	std::shared_ptr< jarray< uint8_t >> &	input,
		std::shared_ptr< jarray< uint8_t >> &	output
	)

virtual

Decap will produce a payload from the packet passed

Parameters

output	- packet encapsulated with DTLS

Implements ProtocolPP::jprotocol.

◆ encap_packet()

void ProtocolPP::jdtls13::encap_packet	(	std::shared_ptr< jarray< uint8_t >> &	input,
		std::shared_ptr< jarray< uint8_t >> &	output
	)

virtual

Encap will produce a packet from the payload passed

Parameters

input	- payload to protect with DTLS
output	- packet encapsulated with DTLS

Implements ProtocolPP::jprotocol.

◆ get_field() [1/2]

uint64_t ProtocolPP::jdtls13::get_field ( field_t field )

virtual

Retrieve the field from the security association

Parameters

field - field to retrieve

Returns: value of the field

Reimplemented from ProtocolPP::jprotocol.

◆ get_field() [2/2]

uint64_t ProtocolPP::jdtls13::get_field	(	field_t	field,
		jarray< uint8_t > &	header
	)

virtual

Retrieve the field from the DTLS header

Parameters

field	- field to retrieve
header	- DTLS header to retrieve field from

Returns: value of the field

Implements ProtocolPP::jprotocol.

◆ get_hdr()

jarray<uint8_t> ProtocolPP::jdtls13::get_hdr ( )

virtual

Retrieve the DTLS header

Returns: - the header

Implements ProtocolPP::jprotocol.

◆ get_security()

void ProtocolPP::jdtls13::get_security ( std::shared_ptr< jdtlsa13 > & sec )

get_security

Parameters

sec	- Shared pointer to hold the security association

◆ hkdf_expand()

		uint32_t	keymatlen,
		std::shared_ptr< jarray< uint8_t >> &	prk,
		std::shared_ptr< jarray< uint8_t >> &	info,
		std::shared_ptr< jarray< uint8_t >> &	okm
	)

static

hkdf_expand that expands the psuedorandom key material into the output key material using the PRK, INFO that uniquifies the output key material, and generates enough material for keymatlen

Parameters

ciphersuite	- Ciphersuite to generate PRF data for
keymatlen	- length in bytes of the output key material
prk	- psuedorandom key for the hash function
info	- optional context and application specific information
okm	- output keying material (of length keymatlen)

		std::shared_ptr< jarray< uint8_t >> &	prk
	)

static

hkdf_extract creates the pseudorandom key using the random salt and input key material (IKM). The PRK is then expanded by hkdf_expand() to create the required output key material

Parameters

ciphersuite	- Ciphersuite to generate PRF data for
salt	- optional salt (a non-secret random value)
ikm	- input keying material (IKM)
prk	- a pseudorandom key of length equal to the hash output

◆ set_field()

Parameters

field	- DTLS field to update
value	- new value for the field

Implements ProtocolPP::jprotocol.

◆ set_hdr()

void ProtocolPP::jdtls13::set_hdr ( jarray< uint8_t > & hdr )

virtual

Update the type field in the DTLS header

Parameters

hdr	- new header

Implements ProtocolPP::jprotocol.

◆ to_json()
