Constructor Detail

PreferredAEADCiphersuites

public PreferredAEADCiphersuites(boolean critical,
                                 boolean isLongLength,
                                 byte[] data)

Create a new PreferredAEADAlgorithms signature subpacket from raw data.

Parameters:

critical - whether the subpacket is critical

isLongLength - whether the subpacket uses long length encoding

data - raw data

PreferredAEADCiphersuites

public PreferredAEADCiphersuites(boolean critical,
                                 PreferredAEADCiphersuites.Combination[] combinations)

Create a new PreferredAEADAlgorithm signature subpacket.

Parameters:

critical - whether the subpacket is critical

combinations - list of combinations, with the most preferred option first

Method Detail

DEFAULT

public static PreferredAEADCiphersuites DEFAULT()

isSupported

public boolean isSupported(PreferredAEADCiphersuites.Combination combination)

Return true, if the given algorithm combination is supported (explicitly or implicitly).

Parameters:

combination - combination

Returns:

true, if the combination is supported, false otherwise

getRawAlgorithms

public PreferredAEADCiphersuites.Combination[] getRawAlgorithms()

Return AEAD algorithm preferences. The most preferred option comes first. This method returns the combinations as they are listed in the packet, possibly excluding implicitly supported combinations.

Returns:

explicitly supported algorithm combinations

getAlgorithms

public PreferredAEADCiphersuites.Combination[] getAlgorithms()

Returns AEAD algorithm preferences, including implicitly supported algorithm combinations.

Returns:

all supported algorithm combinations

builder

public static PreferredAEADCiphersuites.Builder builder(boolean isCritical)

Return a PreferredAEADCiphersuites.Builder for constructing a PreferredAEADCiphersuites packet.

Parameters:

isCritical - true if the packet is considered critical.

Returns:
