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.
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.
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.
