Classes in javax.crypto used by javax.crypto

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.
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.
KEM	This class provides the functionality of a Key Encapsulation Mechanism (KEM).
KEM.Decapsulator	A decapsulator, generated by KEM.newDecapsulator(java.security.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(java.security.PublicKey) on the KEM sender side.
KEMSpi.DecapsulatorSpi	The KEM decapsulator implementation, generated by KEMSpi.engineNewDecapsulator(java.security.PrivateKey, java.security.spec.AlgorithmParameterSpec) on the KEM receiver side.
KEMSpi.EncapsulatorSpi	The KEM encapsulator implementation, generated by KEMSpi.engineNewEncapsulator(java.security.PublicKey, java.security.spec.AlgorithmParameterSpec, java.security.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.
