    • recoverSessionData

      public byte[] recoverSessionData(int keyAlgorithm, byte[] key, byte[] secKeyData) throws PGPException
      Description copied from class: PBEDataDecryptorFactory
      Decrypts session data from an encrypted data packet.
      Specified by:
      recoverSessionData in class PBEDataDecryptorFactory
      Parameters:
      keyAlgorithm - the encryption algorithm used to encrypt the session data.
      key - the key bytes for the encryption algorithm.
      secKeyData - the encrypted session data to decrypt.
      Returns:
      the decrypted session data.
      Throws:
      PGPException - if an error occurs decrypting the session data.
    • createDataDecryptor

      public PGPDataDecryptor createDataDecryptor(boolean withIntegrityPacket, int encAlgorithm, byte[] key) throws PGPException
      Description copied from interface: PGPDataDecryptorFactory
      Constructs a data decryptor.
      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.
