Method Details

getSessionKey

public PGPSessionKey getSessionKey()

Specified by:

getSessionKey in interface SessionKeyDataDecryptorFactory

createDataDecryptor

public PGPDataDecryptor createDataDecryptor(boolean withIntegrityPacket,
 int encAlgorithm,
 byte[] key)
                                     throws PGPException

Description copied from interface: PGPDataDecryptorFactory

Constructs a data decryptor for SED or v1 SEIPD packets.

Specified by:

createDataDecryptor in interface PGPDataDecryptorFactory

Parameters:

withIntegrityPacket - true if the packet to be decrypted has integrity checking enabled.

encAlgorithm - the identifier of the encryption algorithm to decrypt with.

key - the bytes of the key for the cipher.

Returns:

a data decryptor that can decrypt (and verify) streams of encrypted data.

Throws:

PGPException - if an error occurs initialising the decryption and integrity checking functions.

createDataDecryptor

public PGPDataDecryptor createDataDecryptor(AEADEncDataPacket aeadEncDataPacket,
 PGPSessionKey sessionKey)
                                     throws PGPException

Description copied from interface: PGPDataDecryptorFactory

Constructs a data decryptor for AEAD Encrypted Data packets. This method is used with OpenPGP v5 AEAD.

Specified by:

createDataDecryptor in interface PGPDataDecryptorFactory

Parameters:

aeadEncDataPacket - AEAD encrypted data packet

sessionKey - decrypted session key

Returns:

a data decryptor that can decrypt (and verify) streams of encrypted data.

Throws:

PGPException - if an error occurs initialising the decryption and integrity checking functions.

createDataDecryptor

public PGPDataDecryptor createDataDecryptor(SymmetricEncIntegrityPacket seipd,
 PGPSessionKey sessionKey)
                                     throws PGPException

Description copied from interface: PGPDataDecryptorFactory

Constructs a data decryptor for v2 SEIPD packets. This method is used with OpenPGP v6 AEAD.

Specified by:

createDataDecryptor in interface PGPDataDecryptorFactory

Parameters:

seipd - version 2 symmetrically encrypted integrity-protected data packet using AEAD.

sessionKey - decrypted session key

Returns:

a data decryptor that can decrypt (and verify) streams of encrypted data.

Throws:

PGPException - if an error occurs initialising the decryption and integrity checking functions.
