Detailed Description

SMP Long Term Key, used for platform agnostic persistence.

Notable: No endian wise conversion shall occur on this data, since the encryption values are interpreted as a byte stream.

Byte layout must be synchronized with native direct_bt::SMPLongTermKeyInfo

Since

2.2.0

Constructor & Destructor Documentation

SMPLongTermKey() [1/2]

org.direct_bt.SMPLongTermKey.SMPLongTermKey	(	final byte	source[],
		final int	pos
	)

Construct instance via given source byte array.

Definition at line 144 of file SMPLongTermKey.java.

SMPLongTermKey() [2/2]

org.direct_bt.SMPLongTermKey.SMPLongTermKey

(

)

Construct emoty unset instance.

Member Function Documentation

get()

void org.direct_bt.SMPLongTermKey.get	(	final byte[]	source,
		int	pos
	)

Method transfers all bytes representing a SMPLongTermKeyInfo from the given source array at the given position into this instance.

Implementation is consistent with put(byte[], int).

Parameters

source	the source array
pos	starting position in the source array

See also

put(byte[], int)

Definition at line 170 of file SMPLongTermKey.java.

Here is the caller graph for this function:

put()

final void org.direct_bt.SMPLongTermKey.put	(	final byte[]	sink,
		int	pos
	)

Method transfers all bytes representing this instance into the given destination array at the given position.

Implementation is consistent with SMPLongTermKeyInfo(byte[], int).

Parameters

sink	the destination array
pos	starting position in the destination array
