  Class
  Description
  BadPaddingException
  This exception is thrown when a particular padding mechanism is expected for the input data but the data is not padded properly.
  Cipher
  This class provides the functionality of a cryptographic cipher for encryption and decryption.
  CipherSpi
  This class defines the Service Provider Interface (SPI) for the `Cipher` class.
  DecapsulateException
  An exception that is thrown by the `KEM.Decapsulator.decapsulate(byte[])` method to denote an error during decapsulation.
  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.
  ExemptionMechanismException
  This is the generic ExemptionMechanism exception.
  ExemptionMechanismSpi
  This class defines the Service Provider Interface (SPI) for the `ExemptionMechanism` class.
  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.
  KDF
  This class provides the functionality of a Key Derivation Function (KDF), which is a cryptographic algorithm for deriving additional keys from input keying material (IKM) and (optionally) other data.
  KDFParameters
  A specification of Key Derivation Function (`KDF`) parameters.
  KEM
  This class provides the functionality of a Key Encapsulation Mechanism (KEM).
  KEM.Decapsulator
  A decapsulator, generated by `KEM.newDecapsulator(PrivateKey)` on the KEM receiver side.
  KEM.Encapsulated
  This class specifies the return value of the encapsulate method of a Key Encapsulation Mechanism (KEM), which includes the shared secret (as a `SecretKey`), the key encapsulation message, and optional parameters.
  KEM.Encapsulator
  An encapsulator, generated by `KEM.newEncapsulator(PublicKey)` on the KEM sender side.
  KEMSpi.DecapsulatorSpi
  The KEM decapsulator implementation, generated by `KEMSpi.engineNewDecapsulator(PrivateKey, AlgorithmParameterSpec)` on the KEM receiver side.
  KEMSpi.EncapsulatorSpi
  The KEM encapsulator implementation, generated by `KEMSpi.engineNewEncapsulator(PublicKey, AlgorithmParameterSpec, SecureRandom)` on the KEM sender side.
  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.
  NoSuchPaddingException
  This exception is thrown when a particular padding mechanism is requested but is not available in the environment.
  SealedObject
  This class enables a programmer to create an object and protect its confidentiality with a cryptographic algorithm.
  SecretKey
  A secret (symmetric) key.
  SecretKeyFactory
  This class represents a factory for secret keys.
  SecretKeyFactorySpi
  This class defines the Service Provider Interface (SPI) for the `SecretKeyFactory` class.
  ShortBufferException
  This exception is thrown when an output buffer provided by the user is too short to hold the operation result.
