Constructor Detail

SIVAESBasedPairwiseSubjectCodec

public SIVAESBasedPairwiseSubjectCodec(SecretKey secretKey)

Creates a new SIV AES - based codec for pairwise subject identifiers.

Parameters:

secretKey - A 256, 384, or 512-bit secret key. Must not be null.

Method Detail

getSecretKey

public SecretKey getSecretKey()

Returns the secret key.

Returns:

The key.

encode

public Subject encode(SectorID sectorID,
                      Subject localSub)

Description copied from class: PairwiseSubjectCodec

Encodes a new pairwise subject identifier from the specified sector identifier and local subject.

Specified by:

encode in class PairwiseSubjectCodec

Parameters:

sectorID - The sector identifier. Must not be null.

localSub - The local subject identifier. Must not be null.

Returns:

The pairwise subject identifier.

decode

public Map.Entry<SectorID,Subject> decode(Subject pairwiseSubject)
                                         throws InvalidPairwiseSubjectException

Description copied from class: PairwiseSubjectCodec

Decodes the specified pairwise subject identifier to produce the matching sector identifier and local subject. Throws a UnsupportedOperationException. Codecs that support pairwise subject identifier reversal should override this method.

Overrides:

decode in class PairwiseSubjectCodec

Parameters:

pairwiseSubject - The pairwise subject identifier. Must be valid and not null.

Returns:

The matching sector identifier and local subject.

Throws:

InvalidPairwiseSubjectException - If the pairwise subject is invalid.
