Interface Summary

Interface	Description
SecretKey	A secret key for symmetric cryptography.

Class Summary

Class	Description
Cipher	This class implements a cryptographic cipher for transforming data.
CipherInputStream	This is an InputStream that filters its data through a Cipher before returning it.
CipherOutputStream	A filtered output stream that transforms data written to it with a Cipher before sending it to the underlying output stream.
CipherSpi	This class represents the Service Provider Interface (SPI) for cryptographic ciphers.
EncryptedPrivateKeyInfo	An implementation of the EncryptedPrivateKeyInfo ASN.1 type as specified in PKCS #8 - Private-Key Information Syntax Standard.
ExemptionMechanism	An exemption mechanism, which will conditionally allow cryptography where it is not normally allowed, implements things such as key recovery, key weakening, or key escrow.
ExemptionMechanismSpi	The Service Provider Interface (SPI) for the ExemptionMechanism class.
KeyAgreement	Key agreement is a method in which two or more parties may agree on a secret key for symmetric cryptography or message authentication without transmitting any secrets in the clear.
KeyAgreementSpi	This is the Service Provider Interface (SPI) for the KeyAgreement class.
KeyGenerator	A generic producer of keys for symmetric cryptography.
KeyGeneratorSpi	The Service Provider Interface (SPI) for the KeyGenerator class.
Mac	This class implements a "message authentication code" (MAC), a method to ensure the integrity of data transmitted between two parties who share a common secret key.
MacSpi	This is the Service Provider Interface (SPI) for the Mac class.
NullCipher	Trivial subclass of Cipher that implements the identity transformation, where the input is always copied to the output unchanged.
SealedObject	This class allows any Serializable object to be stored in an encrypted form.
SecretKeyFactory	A secret key factory translates SecretKey objects to and from KeySpec objects, and can translate between different vendors' representations of SecretKey objects (for security or semantics; whichever applies).
SecretKeyFactorySpi	The Service Provider Interface (SPI) for the SecretKeyFactory class.

Exception Summary

Exception	Description
BadPaddingException	This exception is thrown during decryption when the decrypted input does not have the proper padding bytes that are expected by the padding mechanism.
ExemptionMechanismException	Signals a general exception in an ExemptionMechanism.
IllegalBlockSizeException	This exception is thrown when finishing encryption without padding or decryption and the input is not a multiple of the cipher's block size.
NoSuchPaddingException	This exception is thrown when a particular padding scheme is requested but is not available.
ShortBufferException	This exception is thrown on an attempt to transform bytes into a buffer that is too short to contain the data.
