Method Detail

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.

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(int aeadAlgorithm,
                                            byte[] iv,
                                            int chunkSize,
                                            int encAlgorithm,
                                            byte[] key)
                                     throws PGPException

Description copied from interface: PGPDataDecryptorFactory

Constructs an AEAD data decryptor.

Specified by:

createDataDecryptor in interface PGPDataDecryptorFactory

Parameters:

aeadAlgorithm - the identifier of the encryption algorithm to use.

iv - the initialization vector to build the AEAD nonces from.

chunkSize - the chunksize value for the AEAD encrypted chunks.

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.
