EncapsulatedSecretExtractor
EncapsulatedSecretGenerator
EncodableService	Encodable services allow you to download an encoded copy of their internal state.
ExtendedDigest
KeyEncapsulation	Deprecated. use EncapsulatedSecretGenerator and EncapsulatedSecretExtractor
KeyEncoder
KeyParser
Mac	The base interface for implementations of message authentication codes (MACs).
MacDerivationFunction	base interface for general purpose Mac based byte derivation functions.
MultiBlockCipher	Base interface for a cipher engine capable of processing multiple blocks at a time.
RawAgreement
SavableDigest	Extended digest which provides the ability to store state and provide an encoding.
SecretWithEncapsulation	Interface describing secret with encapsulation details.
SecureRandomProvider	Source provider for SecureRandom implementations.
Signer	Generic signer interface for hash based and message recovery signers.
SignerWithRecovery	Signer with message recovery.

SkippingStreamCipher	General interface for a stream cipher that supports skipping.
StagedAgreement
StreamCipher	the interface stream ciphers conform to.
Wrapper
Xof	With FIPS PUB 202 a new kind of message digest was announced which supported extendable output, or variable digest sizes.

Class Summary

AsymmetricCipherKeyPair	a holding class for public/private parameter pairs.
BufferedAsymmetricBlockCipher	a buffer wrapper for an asymmetric block cipher, allowing input to be accumulated in a piecemeal fashion until final processing.
BufferedBlockCipher	A wrapper class that allows block ciphers to be used to process data in a piecemeal fashion.
CipherKeyGenerator	The base class for symmetric, or secret, cipher key generators.
Commitment	General holding class for a commitment.
CryptoServicePurpose
CryptoServicesPermission	Permissions that need to be configured if a SecurityManager is used.
CryptoServicesRegistrar	Basic registrar class for providing defaults for cryptography services in this module.
CryptoServicesRegistrar.Property	Available properties that can be set.
DefaultBufferedBlockCipher	A wrapper class that allows block ciphers to be used to process data in a piecemeal fashion.
DefaultMultiBlockCipher
EphemeralKeyPair
KeyGenerationParameters	The base class for parameters to key generators.
PasswordConverter	Standard char[] to byte[] converters for password based derivation algorithms.
PBEParametersGenerator	super class for all Password Based Encryption (PBE) parameter generator classes.
StreamBlockCipher	A parent class for block cipher modes that do not require block aligned data to be processed, but can function in a streaming mode.

Exception Summary

CryptoException	the foundation class for the hard exceptions thrown by the crypto packages.
CryptoServiceConstraintsException
DataLengthException	this exception is thrown if a buffer that is meant to have output copied into it turns out to be too short, or if we've been given insufficient input.
InvalidCipherTextException	this exception is thrown whenever we find something we don't expect in a message.
MaxBytesExceededException	this exception is thrown whenever a cipher requires a change of key, iv or similar after x amount of bytes enciphered
OutputLengthException
RuntimeCryptoException	the foundation class for the exceptions thrown by the crypto packages.
