public class PGPPBEEncryptedData extends PGPSymmetricKeyEncryptedData
A password based encryption object.

PBE encrypted data objects can be decrypted using a PBEDataDecryptorFactory.

  • Method Details

    • getVersion

      public int getVersion()
      Description copied from class: PGPEncryptedData
      Return the version number of the Encrypted Session Key Packet.
      Overrides:
      getVersion in class PGPEncryptedData
      Returns:
      version

    • getAlgorithm

      public int getAlgorithm()
      Symmetric-key algorithm used by this object to protect the session key (getSymmetricAlgorithm(PBEDataDecryptorFactory) with.
      Overrides:
      getAlgorithm in class PGPEncryptedData
      Returns:
      password-based encryption algorithm identifier (SymmetricKeyAlgorithmTags)

    • getSymmetricAlgorithm

      public int getSymmetricAlgorithm(PBEDataDecryptorFactory dataDecryptorFactory) throws PGPException
      Return the symmetric key algorithm required to decrypt the data protected by this object.
      Parameters:
      dataDecryptorFactory - decryptor factory to use to recover the session data.
      Returns:
      session key algorithm identifier (SymmetricKeyAlgorithmTags)
      Throws:
      PGPException - if the session data cannot be recovered.

    • getSessionKey

      public PGPSessionKey getSessionKey(PBEDataDecryptorFactory dataDecryptorFactory) throws PGPException
      Return the symmetric session key required to decrypt the data protected by this object.
      Parameters:
      dataDecryptorFactory - decryptor factory used to recover the session data.
      Returns:
      session key
      Throws:
      PGPException - if the session data cannot be recovered

    • getDataStream

      public InputStream getDataStream(PBEDataDecryptorFactory dataDecryptorFactory) throws PGPException
      Open an input stream which will provide the decrypted data protected by this object.
      Parameters:
      dataDecryptorFactory - decryptor factory to use to recover the session data and provide the stream.
      Returns:
      the resulting decrypted input stream, probably containing a sequence of PGP data objects.
      Throws:
      PGPException - if the session data cannot be recovered or the stream cannot be created.

    • getDataStream

      public InputStream getDataStream(SessionKeyDataDecryptorFactory dataDecryptorFactory) throws PGPException
      Deprecated.
      will be removed in 1.74, use PGPEncryptedDataList.extractSessionKeyEncryptedData() and then apply the dataDecryptorFactory.
      Throws:
      PGPException
