Constructor Details

PublicKeyEncSessionPacket

public PublicKeyEncSessionPacket(long keyID,
 int algorithm,
 byte[][] data)

Create a new V3 PKESK packet.

Parameters:

keyID - ID of the recipient key, 0 for anonymous

algorithm - public key algorithm

data - session data

PublicKeyEncSessionPacket

public PublicKeyEncSessionPacket(int keyVersion,
 byte[] keyFingerprint,
 int algorithm,
 byte[][] data)

Create a new V6 PKESK packet.

Parameters:

keyVersion - version of the key

keyFingerprint - fingerprint of the key

algorithm - public key algorithm

data - session data

Method Details

createV3PKESKPacket

public static PublicKeyEncSessionPacket createV3PKESKPacket(long keyID,
 int algorithm,
 byte[][] data)

Create a new V3 PKESK packet.

Parameters:

keyID - ID of the recipient key, 0 for anonymous

algorithm - public key algorithm

data - session data

createV6PKESKPacket

public static PublicKeyEncSessionPacket createV6PKESKPacket(int keyVersion,
