createDataDecryptor

public static PGPDataDecryptor createDataDecryptor(boolean withIntegrityPacket,
                                                   org.bouncycastle.crypto.BlockCipher engine,
                                                   byte[] key)

Create a new OpenPGP v4 data decryptor. This decryptor can handle Symmetrically Encrypted Data (SED) and v1 Symmetrically Encrypted Integrity-Protected Data (SEIPD) packets. For AEAD packets, see BcAEADUtil.createOpenPgpV5DataDecryptor(AEADEncDataPacket, PGPSessionKey) and BcAEADUtil.createOpenPgpV6DataDecryptor(SymmetricEncIntegrityPacket, PGPSessionKey).

Parameters:

withIntegrityPacket - if true, the data is contained in a SEIPD v1 packet, if false it is contained in a SED packet.

engine - decryption engine

key - decryption key

Returns:

decryptor
