Package org.bouncycastle.crypto

Interface Summary

Interface	Description
AsymmetricBlockCipher	base interface that a public/private key block cipher needs to conform to.
AsymmetricCipherKeyPairGenerator	interface that a public/private key pair generator should conform to.
BasicAgreement	The basic interface that basic Diffie-Hellman implementations conforms to.
BlockCipher	Block cipher engines are expected to conform to this interface.
CipherParameters	all parameter classes implement this.
DerivationFunction	base interface for general purpose byte derivation functions.
DerivationParameters	Parameters for key/byte stream derivation classes
Digest	interface that a message digest conforms to.
DSA	interface for classes implementing algorithms modeled similar to the Digital Signature Alorithm.
ExtendedDigest
Mac	The base interface for implementations of message authentication codes (MACs).
Signer	Generic signer interface for hash based and message recovery signers.
SignerWithRecovery	Signer with message recovery.
SkippingCipher	Ciphers producing a key stream which can be reset to particular points in the stream implement this.
SkippingStreamCipher	General interface for a stream cipher that supports skipping.
StreamCipher	the interface stream ciphers conform to.
Wrapper

Class Summary

Class	Description
AsymmetricCipherKeyPair	a holding class for public/private parameter pairs.
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.
KeyGenerationParameters	The base class for parameters to key generators.
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

Exception	Description
CryptoException	the foundation class for the hard exceptions thrown by the crypto packages.
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.
OutputLengthException
RuntimeCryptoException	the foundation class for the exceptions thrown by the crypto packages.
