  Interface	Description
  SecretKey	A secret (symmetric) key.

    

• Class Summary 

  Class	Description
  Cipher	This class provides the functionality of a cryptographic cipher for encryption and decryption.
  CipherInputStream	A CipherInputStream is composed of an InputStream and a Cipher so that read() methods return data that are read in from the underlying InputStream but have been additionally processed by the Cipher.
  CipherOutputStream	A CipherOutputStream is composed of an OutputStream and a Cipher so that write() methods first process the data before writing them out to the underlying OutputStream.
  CipherSpi	This class defines the Service Provider Interface (SPI) for the Cipher class.
  EncryptedPrivateKeyInfo	This class implements the EncryptedPrivateKeyInfo type as defined in PKCS #8.
  ExemptionMechanism	This class provides the functionality of an exemption mechanism, examples of which are key recovery, key weakening, and key escrow.
  ExemptionMechanismSpi	This class defines the Service Provider Interface (SPI) for the ExemptionMechanism class.
  KeyAgreement	This class provides the functionality of a key agreement (or key exchange) protocol.
  KeyAgreementSpi	This class defines the Service Provider Interface (SPI) for the KeyAgreement class.
  KeyGenerator	This class provides the functionality of a secret (symmetric) key generator.
  KeyGeneratorSpi	This class defines the Service Provider Interface (SPI) for the KeyGenerator class.
  Mac	This class provides the functionality of a "Message Authentication Code" (MAC) algorithm.
  MacSpi	This class defines the Service Provider Interface (SPI) for the Mac class.
  NullCipher	The NullCipher class is a class that provides an "identity cipher" -- one that does not tranform the plaintext.
  SealedObject	This class enables a programmer to create an object and protect its confidentiality with a cryptographic algorithm.
  SecretKeyFactory	This class represents a factory for secret keys.
  SecretKeyFactorySpi	This class defines the Service Provider Interface (SPI) for the SecretKeyFactory class.

    

• Exception Summary 

  Exception	Description
  AEADBadTagException	This exception is thrown when a Cipher operating in an AEAD mode (such as GCM/CCM) is unable to verify the supplied authentication tag.
  BadPaddingException	This exception is thrown when a particular padding mechanism is expected for the input data but the data is not padded properly.
  ExemptionMechanismException	This is the generic ExemptionMechanism exception.
  IllegalBlockSizeException	This exception is thrown when the length of data provided to a block cipher is incorrect, i.e., does not match the block size of the cipher.
  NoSuchPaddingException	This exception is thrown when a particular padding mechanism is requested but is not available in the environment.
  ShortBufferException	This exception is thrown when an output buffer provided by the user is too short to hold the operation result.
